So I'm assuming rings and pulling the head now

With engine warm it's was 290 360 360 and wet test 350 380 380 cylinders 1 2 and 3 respectively

Good point, I'll post back tomorrow after I run the compression test, I really appreciate all of you taking the time to help me, I am an amateur mechanic and all pros In the manteo North Carolina area are booked solid

So thanks fellas!

Yes, that is how I determined that cylinder one is not firing, also then swapped injectors and cylinder one was still not firing, I got a harbor freight compression tester today and will do that tomorrow and go from there,

Amazed that my possible use of ether on a total of around ten starts  or overfill of  oil running for twenty minutes when most of the oil blew out of crank case could have caused a drastic mechanical failure

Ok so cylinder one, farthest from the flywheel, will not fire, swapped injectors and still nothing, any advice please? How should I proceed

Yes pumping water fine

Coolant level seems normal to when I just topped it off the other day, could have gone down some but that could just be from purging the air out

The oil dipstick seems to have risen as I changed the oil after the head replacement and it was just below full and now it's just above full

What do my symptoms sound like? Thanks

Yes, the exhaust, and some out of the crank case breather,

Here's a link to the exhaust photo http://forums.sailboatowners.com/index.php?attachments/image-jpg.127873/

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
