I have the Volvo MD17C, the later 3-cylinder version.

On the picture you include, I notice what appears to be a stainless steel (?) exhaust manifold. That caught me off-guard as it is not an original equipment item.

If you have coolant in the oil, then the cooling system has breached. That happened to me, and it turned out to be the cylinder base O-rings on one of the cylinders. We had to pressure test all three barrels to find it, which meant having to take all three off.

Volvo want about $75 for the O-ring kit for a single liner.

Remember that you will also need a gasket set for the exhaust manifold. They are expensive.

Make sure you budget for all these items.

At the outside, you need to be thinking of about perhaps $200 for gaskets and you have to be sure you have found the leak.

If and when you take the cylinder heads off, look at the coolant levels you see there. If one (or both) of them is not at the top of the liner, then you have a cylinder base leak.

Personally, I would not touch it. I have been caught, and caught badly, by hearing (and trusting) that something "just" needs done.

The last lesson for that (not with an engine), cost me 72 days to fix.
Thanks - I AM being extra careful for the reasons you state. He hasn't fixed it because he isn't capable of doing it himself and he's too broke to pay someone.

I'm still "thinkin' about it" That's why I mentioned spending a few bucks to have the pro's look at it/fix it. I don't need to pay for a survey of the boat so spending some money on the engine instead might be worth it.

"proceed with caution" are my watch words in this case.

P.S. Even if it needed a new engine it wouldn't be a bad buy but I don't want to get in that deep anymore.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
