155 Sluge from exhaust Why?

Kind of agree with winston above. You might want to check into that cylinder in question. Does it clear up after running a bit or does it keep spitting it out. ? Does the cylinder in question get as hot when running ? Should be able to put temperature gun on each individual cylinders to check OR you might be able feel the difference. Be extra careful doing it this old recheck way...normally they don't get as hot as gas motor would..

Depends on how hard you work them more than anything else. Hard working diesels can have exhaust temperatures approaching 1200 degrees (f).

I repainted the green Yanmar to an International paint code. Motor runs just fine but I am getting black sludge from the exhaust." New injectors and pump looks clean and fine."
That is oil in the exhaust. Broken oil Ring is my guess. Exhaust Manifold shows a problem that Diesel fuel won't cause!

People don't use the tractor hard enough, let it work with high load for a couple of hours, and hard means it pulls with all it has of engine power.
