Milk shake oil and.....

[Ed39]

Just picked up a 97 gtx rebuilt the carbs and replaced the fuel lines the ski runs mint. But I found a milkshake oil in the lower unit hose.. I flushed it out ran some new oil flushed it, drained out the oil tank and ran it. It's now milkshake again and I see some oily milkshake coming out of the back of the ski on top. 2 small holes side by side on the top of the drive is now leaking out some milkshake oil. I've done the search and can't find an answer what's going on with this thing?

When the oil looks like that it's been contaminated with water. I'm not sure what you mean by the lower unit hose. Are you talking about the oil injector lines? A picture would help.

They are the two siphon hoses that are from the inside the hull to help bail water. Was there oil in the bottom of your hull? That would explain the milky oil coming from those two holes on the top of your jet pump.

Yes I did notice some oil in my hull I think my oil jug spilt out.. I will recheck the lines to make sure I dot have a leak. The bottom of the engine the big oil line. That's the one that keeps getting milk shaked. I know that's Wat oil and water look like mixed my question is how is this happening? Could it be a head gasket issue? The ski runs mint and I've flushed it once? Or could it take multiple flushes to clear the water if someone before me submerged it?

 

[Tsef]

Maybe an exhaust gasket. Some where paper gaskets that can leak water back into engine and fill it with water.

 

[Ed39]

Where would that gasket be? And if I could get a link on how the exhaust system works, isn't it water cooled or something to that effect. Sorry I'm a noob with this stuff

Click on "PARTS" at top of page, then search for your ski and look for cooling, click on it to see the schematic.

Yea I have looked at that part it looks pretty simple some hoses leading to the block and exhaust. From what I see it would have to be a head gasket? Leaking water back down into the crank shaft?

 

[Ed39]

Well I detrimined the lower base gasket failed I pulled the top end for inspection and it's confirmed. Looks like it failed and was pulling water in on that side the piston is severely scored and the jug has some scoring on it. I'm going to be doing a top end rebuild with some wiseco pistons and probably gonna be boring it out .30. Anyone have any input on this and what power I may gain with this setup?

If you are talking about the oil lines that go from the oil tank to the block are getting water in them there are only two places they can take in water from a blown head gasket or base gasket and that is the rotary valve shaft seal or middle crank shaft seals. If either of those are leaking rebuilding the top end will stop the water entering but not fix the true problem of leaking seals. Are you sure no water is in the oil tank? Oil tank check valve working correctly?

I'm not sure of anything I'm only going off Wat the service guy I talked to said to me. Asked if there was water in the hull if not the only other way would be the base cyilnder gAsket and this is turning into a massive Job the power valve is broken my machine shop said he has no idea how it ran. I test drove it and the thing did 45 it was mint!
