Hi folks.
So last year I picked up an mep-802a at auction, had 6 hours on it. All of the dates say 2010, and it has the fuse mod already on it. Looking inside, it's clean, very clean. So I believe the hours, it hasn't been rebuilt.
When I first started it last year, I noticed a lot of blowby. It would pop the dipstick out. I figured it was stuck rings, and would work itself out.
So I put new Amsoil oil in it of the correct grade, all new filters. Checked the overflow and the coolant looked correct.
Then I ran it hooked to a mobile home I was remodelling. Ran and provided power for maybe 15 minutes, then stalled. Hmmm. Went back outside, fired it up, ran for about 5 mintes, blew white smoke, then died. I was puzzled. Checked again, everything looked great. Let it cool down for about an hour and popped the radiator cap. ****. Empty. I smoked the brand new engine.
So I bought another to get through the job, and am now in the process of working on this unit. I pulled the engine and have it on a stand. After the smoking, it would turn over and blow diesel smoke, but not catch. I got it to catch one or twice with ether, but would only run for about 20 seconds. It never came up to rpm, and ran rough.
So I pulled the head, and a small, maybe milimeter sized part of the edge of one of the pistons was stuck to the valve face. everything else looked ok. I cleaned off the head and it looks very good.
The cylinders still have the cross hatch, but do have some vertical streaks. I plan on pulling the pistons tomorrow, inspecting the bearings, and maybe using some dye to check for cracks.
Other than honing and installing new pistons and rings, is there anything else I should check while I am in there?
I feel like amsoil may have saved this engine.
Thanks
