Okay, had a chance to spend some time working on it tonight. Pulled the codes, the only codes in the computer were low input voltage to glow plugs on banks 1 and 2 which I know I have a glow plug problem because the thing has been pretty hard to start when I don't keep it plugged in. But that's not the current issue.
First thing I discovered when I took the air tube off the output side of the turbo going to the air cooler then the intake was that there was quite a bit of standing oil in the tube. Is it normal for there to be a small amount of oil passing through the turbo on the pressurized air side? My thought when I discovered that was that maybe that oil was passing through and getting into the cylinders, or favoring the left front cylinder for some reason and causing all the smoke and knocking. So I left that tube disconnected and ran the engine for a while, and it just continued with the heavy knocking and terrible smoke. After running it for a while though, I took the temperature off the manifold, and by the left front cylinder the manifold was 420 degrees, but the other three behind it were only around 250 degrees. So I decided to take the valve cover off, and take that injector out to see what was going on with it. Now, I am not real familiar with the powerstroke engine. I have rebuilt a detroit diesel engine, and have worked on other diesel engines, but I am not super familiar with the powerstroke enough to know if what I am seeing is normal or not. When I pulled the injector out of it's hole, a bunch of black oil gushed out of one of the holes around the injector, and pretty well filled the cylinder with oil. Pulled out the second injector back, and got the same thing. Is that oil supposed to be there? The poor running, and the heavy smoke, and the smell of the smoke and the very loud knocking in that left front cylinder only, seems to indicate to me that oil is getting into the cylinder. I know there are two sections on the injector with o ring between them. I know one of the sections has to be for the diesel fuel. And I am assuming that maybe the other section is supposed to have the oil which either acts as an injector cooler, or has some functional purpose for the operation of the injector. I am really unfamiliar with those kind of injectors.
The stupid thing about this whole thing is that I still do not even have a shop manual for this engine. I can't believe I still don't. Just haven't had to do any work to it yet. When I get me a shop manual on Monday it will help me out a lot.
What is a contribution test? And what is a Buzz test?
