Risers/Elbows. Pull all the spark plugs and look for a puddle of water around the white porcelain electrode. Start on the port side...most likely sign will be found on the aft port side plug. When you unscrew the plug..be gentile..you don't want to loose any of the evidence.
If you find puddles on a couple of the plugs..you need a new riser on that side. A pretty easy fix. DJ
