I have a 1984 Ford E-350 Diesel. It was running good untill it warmed up and I started to pull a grade and all of a sudden, it started knocking and blowin'black smoke. So I would stop and let it cool (it wasn't overheating) down and it would start an run good untill I would pull the next grade and it would start knockin' and blowin'black smoke as I reached the top. So after two times I checked the oil and it showed about 1 quart down so I figured it was in the engine. I was at my driveway so I pulled it home after it cooled down. I waited a few days and was going to start it, so I checked the oil and the dip-stick showed it was full to the to top of the block with diesel. My question is where would this diesel come from? Thank You Dirty Bert Confused

How many miles are on your truck?As for when your truck would smoke when your pulling a grade, I am suspecting your injectors are worn and their spraying more fuel into your cylinders than what your cylinders can burn properly. Are your injectors the origanals since the truck was new? I'll get back to you on the fuel in your engine.Hope this gives you an idea of what to start looking for.

wow, this sounds like kind of a dangerous deal, i don't know alot about diesels but common sense would tell me that that is really bad. now i am by no means any kind of certified mechanic and i may be wrong, (guys help me out) but i would think that you are gonna need to have your whole oil system flushed, and if your injectors are leaking into your cylinders and it is making it down into the crankcase, then you are probably in for a crapload of work for her... probably a whole engine rebuild... but don't take my word for it...

As for your fuel in your engine,i am know thinking that your rings are worn out.Thats probably how your crankcase got full of fuel,The fuel that wasn't burned leaked past your rings into your oilpan. Your engine is most likely going to need to be flushed out,including your crankcase. I hate to tell you this, but you might be better off doing a full engine rebuild.

If I am not mistaken ford used a gear driven fuel pump and I was thinking of any place fuel could come into contact with engine oil it would be through the drive gear seal if you were getting fuel in past the rings the engine would probably not run if an injector was putting that much fuel into you engine. your running engine would push it out the exhaust so if you were to pull your exhaust you should see a lot of fuel otherwise you just need to think of where fuel comes in contact (or sepperated by gasket or seal) as fuel will be a much higher pressure and will go to the oil side. hope this helps.
