So here goes my first post to this forum...
I changed my oil this past weekend and noticed there was some coolant in it. The oil was milky (I had just run the engine up to temp) and there was a little that had separated at the bottom of the pan. It is a 2003 6.2L closed cooled inboard with about 350 hours, and has been running fine. I have not had any issues with overheating since I bought the boat.
I have already checked the coolant, and it was good for temps well below what it saw over the winter so I think the block is OK.
I also ran a compression check. All cylinders were between 160-180psi with no slow leak of pressure, so I think the head gaskets should be fine.
I'm not sure if it is related, but I did see a couple of drops of coolant below the front of the engine the last day of last season. I haven't been able to pinpoint where that was coming from.
I have read about coolant leaking into the block through a seal on the back of the water pump, but have heard that's not possible on the 6.2. Is that correct?
Anybody have any thoughts? My thinking right now is a bad intake manifold gasket.
Thanks in advance.
