Hello all, thank you very much for any advice I am stumped and cruising and trying to get this engine all sorted. I bought it in January from a trustworthy fellow who said he had rebuilt it all including new rings and pistons and used it flawlessly for a season and now I'm having trouble with it.
When I first dropped it in the boat it ran fine except leaked a bit of oil out of the head so torqued all head bolts to spec and decided I needed to put on a new head gasket but that it could wait till I got to the outer banks. As I was traveling I motored one long day where the engine did fine then the next morning the low oil pressure light came on and I assumed it had leaked oil and misjudged how much and accidentally put in about 1.5 quarts too much which it blew out the breather.
After this she will start and run fine in neutral (little hard to get started) then when you put her into gear she will want to die at idle but if you throttle up you can get her to run for about 20 minutes @ about 1500 rpm full throttle then the low oil pressure light will start to come on gradually at first and the engine will die, also there is a lot of smoke and a bit of oil coming out of breather
I then changed the head gasket and the symptoms are still the same with the exception that oil is no longer leaking from the rear of the head,
Any advice is greatly appreciated as this past week has just been constant stress about the engine as were planning on leaving in a week for the islands
Thanks! And I'll attach a pic of the smoke
