SL750 with oil filled crankcase
Good day to all!......Need some help please. 93 SL750 that I aquired from a friend. It had tried to digest a piece of metal through #3 cyl. I removed the cylinder and the piston and noticed the crankcase is full of oil. It has been setting for at least 2 years. Does anyone have any ideas how the oil got here and how to drain it. The engine is still in the boat. I will also like to find a cylinder and a head gasket for this motor without buying a complete set as I will be replacing just the one piston and cylinder. Thanks for your help.

Welcome to the Hulk. How much oil are we talking? If someone was smart, they fogged the engine to prevent steel parts from rusting. And for your cylinder parts, one word, Ebay! If not, there are a few members you can get parts from in here, like John Zigler, or Surfjetlouie.

nu Welcome to the hulk
There are three drain bolts on the exhaust side down low. If no one here has any piston and cylinders you can check with our resident (Sanford And Son)

The crankcase has oil up to the top of the case.........I am looking at a used piston,rod bearing, and cylinder on ebay. I am not sure of the volume of the crankcase but it looks like there is at least a quart in it.

The oil probley sifon down from the oil tank and just slowely leaked oil into it over the two years that it sat. I know mine gets some in there from just sitting between uses, and when I first start it, it will kill all the masquitos for miles around. LOL

Thanks Rodneyae, I was hoping there was a simple explanation. While I am reviving this old hulk should I go ahead and block off the oil pump?

I would just for an extra piece of mind. I have blocked off one of my skis and plan on doing the other after this season. Just a little insurance, or replace the pump with a new one, but that is a lot more expensive.
