Re: Rebuilding Yanmar 3GM30F; need advise $?
Sorry for butting in but...
I just started a 3 GM 30 F and it ran fine with good oil pressure. ( only ran it for perhaps 2 or 3 minutes )
I shut it down and set up water to the system as she is setting on the hard.
When I started her this time I had very low oil pressure. ( I checked before I started and oil looked good and was close to full )
Can anyone give me some advice on this.
I have rebuilt engines in the past so expect if I must that is how I will go.
Thanks to any who reply.
