Ok, here's a puzzler.
We have a Chrysler 318, I believe a 1961, 3 bolt valve covers. A few years back it started getting water in the oil. we pulled the heads, had them checked, replaced all the gaskets and reassembled the engine, same result. then I pulled the engine, found a bad gasked on the timing chain cover we thought could be responsable, reassembled and - same result. Then we found some cracks in the exhaust elbows, thinking that water could be draining backward into the cylinders when the engine is shut off we replaced the elbows. This time we thought for a second that we had it fixed. However when I took the boat out and started to wind it up it suddenly started pumping out tremendous volumes of blue smoke and lost power. I'm at the end of my rope. Compression numbers are good, gaskets have all been replaced. What could this be?
Any help greatly apreciated!

Joe it sounds like you could have a blockage in your crankcase vent, If not venting correctly it would pump oil into the cylinders causing the smoke and power loss. I hope it is as simple as this, good luck, I may have some marine 318 parts around the shop as I junked one out several years ago. (block & heads were bad)

Joe, water in the oil may be a result of a cracked block.Chrysler engines retain water even when drained, there are frost plugs at the rear of the block, behind the flywheel to protect the block from freezing damage.If you live in a seasonal ( read cold ) climate, the engine may have frozen and cracked. The block can also crack from heat, stress, or weak casting. You may want to pull the engine, and have it tested. Hope this helps, regards, Ron

What temp range is your thermostat...if the engine isnt getting hot enough, water could collect in the crankcase.
