As some of you know, we went on a trip recently across the OWW for Ft Myers to Stuart and back. Three boats left and only two returned. Here is why.......OUCH!

This first group is of the heads after I removed the intake and cleaned up some of the goop.

This second group is of the intake-gone-bad....

If you look closely at the second to last photo, you can see the 1/4 inch hole that sucked in the St Lucie Waterway. As a result of the water ingestion, several other boats went aground due to a lower water level.:doh::shocking:
I saved all the water and brought is home with me.:garfield:

Any guesses on whether I can salvage the heads?

Obviously, there is no salvaging the intake manifold.

Mercury in their infinite wisdom coated the water passage with copper, anyone that know even a little about electrolysis knows they created a problem for any boat running raw cooling in salt water. The problem even pops up in some fresh water locations, the manifold last I checked was on the + side of $500.00. Why the coated it is a mystery, a plain aluminum intake lasts quite a bit longer. Go Figure!!!

Is the intake cast iron, or aluminum? Either way, I don't see it buiding up enough pressure to shoot out the oil as you decribe. I'd go ahead and pull the heads anyway. The intake is harder. Just 16 more bolts to pull, per side.

How badly are the heads burned/corroded, I have seen them patched with fillers. I know of one set that they tried to weld and cracked them. If you go the patch route you need to pull the heads and blast the bad area fill it and mill it back down for a good fit.

------I dont know, Phil. A decent pair of correct #s automotive, used heads make it almost a no brainer to use his current heads as anchors. Even new iron heads made in the aftermarket probably flow much better (CFM wise) and are pretty darn cheap. It may be just me but I would never use the heads I have seen in his pics.

I took a closer look at the manifold and heads. It appears that no water flows normally through the rear ports just the front ones. All the corrosion is on the rear ones. The fronts look fine, on the intake.

I took the gaskets off the heads and started to clean them up. They appear to be ok other than the rear ports being clogged with oxidixed aluminum junk that come out like paste.

Here are some more photos. The first two are the heads after the gaskets were removed.

The others show the holes in the rear of the intake, amazing how the gunk filled the hole and didn't allow water through the intake into the the engine compartment.

The last two are repeats of the two front intake ports, the ones that allow water flow, they aren't all that bad compared to the rears.

Jim, Bill, others

Seeing the new pictures and the condition of the heads, would you still say replace them?? They look pretty good.
Am I not looking for more problems if I replace the heads with new tight ones, without now doing the rings, etc? At some point, if I keep going, I have to stop and consider the $$$, and think about a repower.

Looking over the photos again it is a little hard to see what is really going with the heads, it would be nice to see the back water passage areas cleaned up, get all the aluminum mess cleaned off & out then shot a pic and post it. Ted could very well be right the heads may not need to be trashed, the ones I have seen the back passages were not destroyed, the fronts were eaten away.

I had my Weiand Stealth intake anodized for salt water usage. The original GM alum intake that was on the old 454HO had corroded so in one passage that it had cracked a wall in the port. I'm also using Salt-a-Way each time I flush. If you pull the heads, you might consider a valve job. Valve springs that have been getting damp will get weak and will break.

Agreed. Take a close look at the heads while you have them off. They look ok.

The manifold on the other hand! ouch.

I don't know how long I had standard Merlin intakes on the Formula. They were on there when I bought it, and I had it over five years. Just a couple months before I sold it, I pulled the thermostadt housing off, to check for corrosion. I didn't see a sign of it. I usually put some Dawn in the hose, and flushed with it. I knew when it quit bubbling, it was totally flushed. And I'd flush it some more.

Tidbart

I am in the process of cleaning out all the leftover goop. I just pulled one valve cover and that steel pan from below the manifold. I have remove all the goop I could, 99.9%, and then sprayed them down with WD-40, same for under the pan. Other valve cover tomorrow.

Here are the photos I took after the cover removal.

I will be back at it tomorrow afternoon.

Hopefully, that corroded intake was your problem. I'd be willing to bet, you'll be okay after replacing it. Our local mechanics down here in "saltwaterville," are accustomed to this. They say those intakes on the MPI motors are usually only good for a handful of years. Seems that anything "7ish" years old is on borrowed time. (in saltwater)

I can't believe these guys who never flush their engines in boats that stay in the water. Supposedly if "air" isn't introduced into the raw water passages they won't corrode...Oh contrare... (spelling?)

The only motors we typically see with over a thousand hours are freshwater cooled. One exception was an 82 Carver 30 with 1400 hours on raw water cooled Ford 302's. She was owned by a former U.S. Marine who RELIGIOUSLY flushed her after every use. ...go figure

I hate to tear down my good running 99 7.4 MAG MPI, but if I make it through this season, I'll probably take her out inspect and TWEAK. Like some of you, I also use Saltaway for every flush. Hopefully it helps...

Best of luck Bob, if you need help with anything, just holler.

By the way, your boat is SAWEEEEET!

Thanks Nate. Looks so far to be the problem. I will keep this post going as I move along.

Interesting that the manifold corroded away where the water is blocked off. Buizilla and I spoke about a possible solution for the next one. Will keep you posted.

Nate, an indicator of the same type of problem as I have. Look at the rear manifold bolts, down back of the engine, hard to get to see. Look for signs of gray paste forming in the area. That is what mine did prior to this event.

You do have a point though. I am constantly amazed what used manifolds and headers bring on e-bay even with salt water usage.

I see lots of exhaust stuff going at 80%+ cost of new. That is crazy. I have jumped in before thinking that 40% of new might be a risk worth taking, get out at 55% and see them go at 80%. Heck, you could pay 20% more to know it is good and have a warranty.

Bob - I'm a little late in the game here, and I have no input on how Good the heads are, but I do know welding and IF the heads are cast and IF they need build-up repair, that will be VERY hard to get right.

Technically, it can be done (they taught us that in School), but it is extremely hard and not very reliable in most cases...Generally, the weld will crack even before the welder is finished with it...Be careful.

-----Bob,,,I might revise my opinion on the heads once you send them out to find out about them. There is probably a case to be made for checking deck straightness here. Also wonder about the deck being parallel to crank, and head warpage. Sorry to throw any curves at you but do you think the bearings may be compromised??? Thats a lot of milk to have passed over your bearings to suffer absolutely no damage. Im assuming you already have had a looky at the cylinder walls.........Bill S

For now I am going on the assumption that the heads are good. The intake I know is bad as I can see where the water came into the engine. So intake first, then I;ll see if there are head problems, which I doubt.

if it were my boat i would put the x-tra hours in it and pull the heads,most likely the head gaskets are most likely in the same condition..i would probably have them inspected for perosity and throw a valve jod in whyle it was apart..

Not to fuel the fire, but we've seen this same problem many times. "Usually," if the engine's pickled in time, it's okay to just replace the intake. Sure, it's never a bad idea to pull the heads and possibly the lower end, but in this case, we'd bet he's okay with a new intake.

Let's just hope so....

Maybe the heads are fine. If any of that water from the intake, made it to the backside of the valves, I don't doubt there will be a compression problem further down the road, as rust develops around the seat. I know that from experience. :( Btw, to rebuild a set of SBC heads, and have them checked at a machine shop, only cost me $150, the head gaskets were damn near that much. Not much work, or expense, for the peace of mind, not to mention, having to pull the intake again, if the compression goes low.

Remember, that watery oil went down the valve guides, and rust never sleeps. It doesn't take much rust around the valve seats to lose compression. You'll see it get worse, and worse, as the rust develops.

Heres some pics of one i did at the end of last season that came up from florida with a bad intake..i ended up going through the whole engine due to the excess rust build up from the salt water.. see all the rust in the lifter valley wait til you see how much is getting thrown around in the lower end..your crank and rode probably look the same:wink:

Yes, I see it and it is well noted. My main concern since this weekend has been to preserve the engine as best I could. Removal of the heads is still part of the equation. Of course my original thinking/hoping was not to have to do more work than I had to under the 'if it ain't broke......' rule.

Here is what I have done the last day or two. Thoroughly clean any and all goop from every place I could see and get to. Coat everything with WD-40 numerous times. Today, with the heads still on, I got an oil pump tool for the distributor. Put 5 quarts of diesel in the block and ran the pump. Stopping occasionally to rotate the motor. Repeated this for about 20 minutes. Then drain the pan and replace the oil filter.
Then I repeated the process again. The second time around most of the white stuff is gone.
Tomorrow I will run one more flush with diesel, replace the filter again, fluid should be totally clear by then. Then I will do a final with motor oil and coat every thoroughly.

Then I can think about the next steps. Heads, intake etc.

Part of my reluctancy has probably been the fact that I have been doing this all alone. I will definitely have to get help with the manifolds and heads if and when they come off.

That's my update for today.

By the way, I really appreciate everyone's help. It is comforting to know that I can count on all you guys, some I don't even know, for advice in a time of need.:yes::):bighug: Thank you! It means alot to me.

Try pulliing a lifter or two and looking into the crankcase beyond the the canshaft to see if your lower end whipped a greecy mess,, when the engine rotates with all the water thats in the oil it turns into a greecy looking mess and somtimes you have to run the engine and warm it up to get rid of it.

If it ain't broke don't fix it! In the 30+ years that I was on the wrenches all in salt I never tore one apart that had been pickled properly or pulled up and started right away. I feel Bob has done a decent job in fact more then most marinas do to save a motor, can't believe some insist on tearing into the engine more then he has.

Question for you, as I really haven't gotten this deep into an engine for a very long time and when I did it was with someone who new what they were doing. Excuse the lack of proper terminology. Below the big pan, which I removed, at the bottom of the rods are the lifters, correct? There is a small steel pan on the bottom of the valley with 3 or bolt in it, not sure of its function. If I remove that pan, the cam is just below it. What does the small pan do and if I remove it and expose the cam, can I see into the lower engine for a visual?

If it ain't broke don't fix it! In the 30+ years that I was on the wrenches all in salt I never tore one apart that had been pickled properly or pulled up and started right away. I feel Bob has done a decent job in fact more then most marinas do to save a motor, can't believe some insist on tearing into the engine more then he has.

Thanks for the positive feedback Phil. Tomorrow, I will get some update photos of what I am seeing and post them.

Yes remove the lifter valley tray then remove the steel roller lifter guide plate hold down and simply remove the lifters but dont mix them up,make sure they go back in the same holes..

Yes some of the suggestions others on here may be correct but its vary costly if it just so happens to fail..
Take into consideration how many hours are on the engine and how hard do you run the boat and how long water from
the intake manifold has been leaking into the oil..we all just dont know if it has caused other damage to the engine,correct me if im wrong but isnt salt water slightly gritty like a vary fine sand after it looses all its moisture.

Just to clarify the events of this occurrence. I ran about 120 miles across fresh water, went through a lock into brackish, ran about 1/2 mile mostly at idle. Engine started to run slightly rough. Alarm went off, I opened hatch, saw spew, shut down. My guess is that some water is fresh and some brackish.
Also, after getting it home and trying to get the foam out, I refilled the crank with oil and diesel mix and ran it for a couple minutes, twice actually, to loosen/ dilute the crap and drained it.

2 days before trip, I ran it in salt for a couple hours in Naples. Prior to that I ran it in fresh water for a few hours. I did check the oil before heading to Naples and Fort Myers and it was clean and clear.

If it started ingesting water prior to that OWW run, I wouldn't think I would have made it 130 miles in 5 hours of continous running.

This is a salt water boat, at least for the past 5 years. I just got it in October. Knowing the previous owner kept the boat in Fl and lived in MI and had a storage place take care of it, I would expect to see trace amounts of surface rust in places due to it not being fogged when stored for months at a time.

Bob I do think it was ingesting small amounts of water but not much until the big hole. When corrosion starts it never sleeps. This is the main reason I use a closed cooling system. You see unless you flush with an open T-stat for a half hour there is still salt in the engine. This is also the reason the 496 has a closed system! I know I am opening myself to a long discussion but I would use a closed system with at least 50/50 antifreeze and water. I won't discuss this point because it is in the archives so anyone who wants more information on why look it up, my hands get tired re typing it all!

By the way, Ranya says hello.
I don't know if you should put CC on after that much salt usage. The block itself, will absorb salt, and if you put CC on it, it willl leach out the salt, making you coolant into brine. I know for a fact that the salt gets in the block itself. Once, I pulled a set of heads off a raw water cooler saltwater engine. I had the heads off for about a month, and where the coolant runs through the block, there were small pyramids of pure salt, that must have leached out due to the moisture in the air. This is not second hand iformation, I had pictures of it one time, that I have since lost. It was amazing really. Like I said, the engines in my Formula were 22 years old, and 99% of that was salt usage. Just have to flush, then flush some more.

MOP
05-06-2008, 06:11 AM
Bob go with a cooler, it is far easier having a cooler boiled out when you see the temp creeping up then going through this again. I have put coolers on several all salt motors with good results, Run a mix of salt away for a week or so then flush and put 30% antifreeze that will stop any further corrosion in the block. You do not want to go through this again in a few years.

I respectfully disagree. I don't think he'd ever get all the salt out of the block, and I think it would just compound his problem. I'm telling you, it looked like someone took a pound of salt, and made those pyramids I saw on that engine, and that was only the salt I could see. I have no doubt there was more.

BigGrizzly
05-06-2008, 08:36 AM
Actually with what Mop said is correct. Trick is the salt away it is good stuff. remember the intake is trash which is the main salt keeper, the iron block is scaled and Salt away or salt terminator will take care of that. However I run 50% antifreeze in anything aluminum. Learned this at Honda, anything less and cylinder heads(aluminum in Hondas) have a problem, mainly because og heat. Anyway I use that blend in my engines, no over heating and no other problems after 6 years. To clarify what Cuda says in the older pre mid 70's blocks had a different iron Bock mixture that was more porous and had the salt retention problem especially in the 1960's and earlier.

Found some info on the newer manifold. It was used on the last series on 502s OL085433.......+. The diff is in the fuel system. They changed the injectors to a GM? type from the Keihin type. What that means is that I can't use my fuel system with that intake.:garfield: As to why it so significantly cheaper, I haven't the slightest.

One hurdle down, intake is being shipped in next day or two, should be here next week sometime.

Next step, retest the leakdown with a second tester, just to verify the good readings. If they are still OK, then I am going to leave the heads on and replace the valve springs and shields. Tired springs are the possible cause of lower than expected rpms.

Don't see anything scary just a lot of senseless work, from the pics it looks as I suspected it would. The low pressure leak down readings were very good, high pressure leak down should be done with the engine warmed up just like a compression. A cold block will rarely give proper readings. My money still stands on should have just gotten it running, you would have never known it had gotten wet. It is not like I have not done way to many of these and I am talking all salt full submersions some down for several days that the engine came out fine, they lost the wiring & electronics etc but ran fine for many years afterwards. Even outboards usually come through a sinking if caught soon enough, only the real early John/Rudes that had the magnesium crank case filler blocks had to come apart.

There was more to the story than I had time to post. The second time I did the leakdown, with a better tester, the results were a lot different. They were more in the 30-40% range. Also, rust was also everywhere around the block and had eaten away at a few of the head bolt and brackets, etc. It was my decision based on these items, as well as a few more, like painting the bilge, that led me to do it now. I agree, from what I am seeing first hand, that there would have been no problem getting the engine up and running without problems.

My decision is based on my gut and the future I want to have with the boat. Taking it apart now is solves a few issues for me, 1: now I know the condition of my motor, removes the guessing 2: I am learning a lot of new things here 3: I'll be equipped for the next ten years, if I waited a few more years maybe I wouldn't be so lucky when the next item fails. 4: I get to buy more tools!:wink:

Also, the only thing I have spent so far has been my time, which I apparently have a lot of....:doh:.

The rings would not cause water in the oil, and as MOP said, it's hard to do a leakdown, on a cold engine. My gut feeling is the rings, and cylinders are fine. Maybe a valve job, I'd say.

Let me correct myself on the last post. You have already asertained the water/oil problem was from the intake. I was thinking about compression, and the fact it was blowing the water/oil out. That still sounds like a headgasket to me, if not a cracked, or warped head/block, which I really doubt.

Found a machine shop in downtown Orlando with some very knowledgable and experienced BBC guys. Just dropped it off this morning. First words out of his mouth was, "Seen worse". That is encouraging.:doh::wink: Next step is to finish tearing it down and inspect and test. Will know more next week.

Bob

I wish you luck with it:) and everything works out for you..

Here are some updated photos. Pulled the engine, tore it down. Still have one head to go. Rusted bolts suck.

First photo, jack didn't go high enough.:doh::hangum: Had to rig something to the trusses. Rest are of the motor. Spooge was all gone, some left in the bottom of the pan.

Got the new-to-me intake today. Looks great. Thanks once again to Rob (obsessed1). Bob,
Glad I could help. Good luck in your next steps. Rob

That's not far from where I lived for 33 years, and my parents still live in the Park. With the Nelson name, they must be related to the Nelson Bros, who have a stellar reputation.

Here are some updated photos of the engine. I don't remember if I posted that I found a good shop right here in Orlando, very knowledgeable chevy guys. Anyways, they have been working on the block and heads and I attached a couple of photos. The heads are done and the block is started.

Turns out the heads and block are in great shape. Nothing was damaged in the incident. All that flushing and hard work paid off.:):beer::yippie: The machinist said it the best looking motor, internally, from a boat that took on water that he has ever seen. Turns out, most people bring the motors in weeks after flooding and have never done a thing to them, not even drained them. So most are ruined by the time he gets them.

All the wearable parts are being replaced, seals, bearings, rings, springs, gaskets, timing chain, ARP bolts, cleaned painted, reassembled, etc.

In the meantime, I am cleaning and painting the bilge.:garfield:

I am glad I made the decision to pull the motor. It turns out MOP was correct in that I could have put it back together and run it without all this work, but there were other factors involved that I won't boar you with in making the decision, the main one being knowledge.

I think you did the right things from the start. The machinist is correct!! People usually get POed and wait too long and salt water is a real killer Fresh isn't too bad-all depending on how long it is run with it in it. Every time I was going to make a suggestion you were already on top of it, so there was no need. The bright side is that you now really know what you have under the hood and YOU control the maintenance. Great luck.

I did inquire about the balancing, what is checking the line bore on the crank and zero decking the block?

In case anyone hasen't noticed, I am not real experienced with engine rebuilds. :wink: My philosophy has always been to keep up with the maintenance so I didn't have to rebuild anything. It has worked up until now.:doh: Although, I couldn't have notice this one coming.:shocking:

line bore is when they machine the main caps down and line hone where the crankshaft main bearings rest,this trues the crankshaft with the cylinders,i would just havr then check it.. it may not need tobe done..

zero deck is when they machine the serface of where the cylinder heads sit,most pistons are abour .020 in the cylinder below the deck height,machineing it to zero will bump up the compression a little and will give you a better fuel burn whit the end results more power..

That makes sense.:doh:

You guys kill me. You just can't help but want to beef up the ponies. LOL
My intention is get a great running dependable motor out of the deal. I am not really interested in the 80 mph club. You also have to keep in mind that this is a MPI setup. I just can beef up everything and not have it impact something else. Not as easily beefed as a carbed engine. I spent a couple of days researching the removal of the water circulating pump. Something that simple got a little crazy with the dollars and in the long run wasn't worth the headache as I have 2 sensors in the thermostat housing that need to be there or it will drive the ECM nuts.

Anyways, for me to get a good running dependable engine is priceless. I am not saying that I couldn't have the same after upgrades and all the input and suggestions have been great and are appreciated.

What I am getting out of all of this is a great education, though. Can't put a price on that. :cool:

Bob from some body who does a lot of this, I feel you are making the right decision. An EFI is much more difficult to work with, there are always trade offs. I did what I did because it was easier and cheaper for me, mine is a carb.

I agree. I can help anybody out that has a carbed engine, but go to EFI, and they're on their own. :garfield:

At that point, why not be a member of the 80 mph club! The parts basically cost the same amount.

Well, maybe not but for a few more pennys you are there.

Yes, EFI is a pain to set up. But once you do...well ask Dr. Dan and others that have nice power EFI's. Clean and reliable.

I am running out of pennies. :eek: I did put a lot of effort into replacing and cleaning every rusty bolt, nut, bracket, you name it. For now this is the best place for the dough. Someday....... who knows.
