888 1977 model milkshake in oil

[vstroker]

My port engine recently got the milkshake in the oil syndrome! Engine was running well, although had a little spark-knock/pinging at speed under load.<br /><br />Engine is fresh water cooled, run in salt water.<br /><br />Question: Where should I look first for the problem, ie trouble shooting process?

I just finished re-assembling my 888. I would chek the risers first then the manifold gaskets.

Jasonnb,<br /><br />I assume you are talking about the manifold to head gasket. Would this let water into the cylinders? I just did a top engine job on the starboard engine because of a blown head gasket caused by a poor instillation of the lower unit,(mecanic was a butcher) which caused the salt water p/up to fail. The engine ran hot and warped the head on one side. Needless to say I had to re-repair myself. Engine shop sold me a set of virgin (never been used in water before,set them up for marine and they worked great!)

Sorry, had a brain cramp. I don't think a leaky head-manifold gasket would cause your problem but I may be wrong. That would leave the Riser/manifold joint and Head gaskets as prime suspects. Also, I would check the Intake gasket. May be getting time to pull the heads and just re-seal everything from there up. Then you could be sure you gotthe problem.

as far as I know, the only way to get water into the crankcase other the pouring it into the filler pipe, is a cracked casting or a blown head gasket.........good luck

Dont we mechanics love those saltwater engines!!<br /><br />Time to pressure check the manafolds and risers. If these are more than five years old and live in saltwater...REPLACE THEM NOW!! Very common!!
