Posted in another help thread about a 2002 7.3 in a truck I bought. It has multiple issues so I am trying to sort them one at a time.
When I unloaded it off the transport, it started instantly. Drove it into the shop. Checked the oil and it had about a gallon too much and smelled like heavy diesel. Was pumping fuel/oil out the exhaust, missing badly, and smoking to beat hell.
First thing I suspected was turbo seals. Pulled off the intake hose from the filter, and the pipe from turbo to the intercooler, was going to take a look. Started it and let it run for about ten seconds. before I could get out of the truck to look, it absolutely hosed the engine compartment with oil!!
OK... I still am not sure where it's coming from, but its not going to get started again.
Next thing was why it had so much diesel in the oil. If I understand correctly, the hpop should [I]easily[I] overcome fuel pressure, and I should have oil in the fuel, not the other way around.
Pulled the fuel filter cover and fuel looks clean and fresh. So if an injector seal let go I would think it would let oil into the fuel.
Cracked head?? No oil or fuel in the coolant. I drained the radiator and the coolant also looks clean. Used but clean.
Decided that before I put a lot of time and money into the top of this thing I would check the compression, and see if I had a good foundation to work from.
Glow plugs came out with very little resistance. These thing were in no sense of the word "tight". My concern is, two of them (#1 and #3) came out with about a quarter inch of the tip missing!! Is this common??
I turned the engine over about ten revolutions with a socket and breaker on the crank, in case the ends were still in the cylinder. I did not want to screw anything up doing the compression test with the starter.
Did not encounter any real resistance with all the glow plugs out. Do I need to pull the injectors on those two cylinders and insert a small vacuum tube in the hole and suck them out?? I am worried the missing tips may have fallen onto the piston dish, and turning it over with the starter might be fast enough to toss them.
I will have to get the proper fitting for my compression gauge before I can test. I realize this might be boring and tedious to a lot of you guys, but I am trying to make this engine run without pulling it, or putting in a replacement.
Any advice would be appreciated!! Here are a couple pics, the glow plugs in question, and the pool of oil left in the intercooler pipe.[IMG]
Hope that worked.
