I've been looking at a 756 that's gonna go on auction. Went and drove it today. Everything looked pretty good besides looked like unburnt fuel coming out the bottom of the muffler and fuel or maybe oil weeping just a bit out of the exhaust manifold. Any info on this is a great help. Thanks
 
I have a 666 that dose the same thing if let idle to much but put it to work and clears up and a lot of power. We put in a different thermostat that warmed it up faster and run it about 1000 rpms when not working . International said it was the nature of the engine , this one has over 7000 hours and no issues .
 
My Massey Perkins diesel did just that, til I got around to actually reading the owner'[s manual. It says do NOT warm it up just loping along, but get her going and then warm it up at 1200 RPM for 3 minutes. Then operate it at 1700 RPM. I do that now, religiously, and it stopped the diesel out the exhaust, and runs much better.
 
im rebuilding one for FFA shop class and yesterday we had it running and it was smoking when it was warm and when you get into it it burns to beat hell, our conclusion is it needs seals and new oil rings, anybody have any imput?
 
?Has anyone had trouble with the starter not working good on a 756 D310? rebuilding one in shop class FFA i have to tap the starter button and use a screwdriver to make the conection kind of. its rednecky
