Hi folks, I've searched the forums for answer to my problem, but thought I'd throw it out as I'm still a little unsure.
My 1986 Mercruiser 3.0 liter started getting a little water in the 2 & 3 cylinders after the engine was cooled. If I remove the spark plugs, blow out the cylinders it starts and runs smooth as a sewing machine, as always. While it is hot you can shut it down and re-start no problem, let it cool and there's water again.
I've owned it since almost new, it's always been well cared for with no mechanical problems at all for 25 years. Engines never been cracked open. It doesn't have that many hours on it, mostly a one day a weekend boat for 10 trips a year. It does run very well when running even now.
I'm thinking head gasket, although it's never been overheated, maybe underheated as I run it in the ocean (in Maine) and it never develops a lot of heat,
or
cracked head, I see that a lot on here and seemingly a result of running an engine with a blown head gasket, so both
or
a cracked blocked, which usually means the engine won't run for long or water will be squirting out everywhere or filling the crankcase. I hope this isn't the case.
I am going to do a compression test tomorrow, but don't want to tear the engine all to pieces to find out the block is cracked and it's none repairable in the event of an uneven result which I'm sure will be the result of the compression test.
Thank you all for your help
