[MBZ] update on my 2.5 turbo

[Kaleb C. Striplin]

Messed with it today.  You all recall it smokes real bad(well bad but 
not REAL bad, I have seen worse).  Anyway, I found out for sure #1 is 
not firing at all all.  Pulled all the injectors, pop tested them, 
cleaned out the holes and pulled the prechamber rings.  Non were 
cracked.  INstalled new seals and put injectors back in.  No change. 
Swapped out #1 injector for a different one, still the same.  With the 
crossover pipe removed, there is a loud chugga chugga type sound, like a 
valve sticking, or something like that, either air blowing or air 
sucking.  Should not make that noise.  Also the oil pressure seems to be 
dropping again like there is fuel in the oil.  I would assume all the 
fuel from #1 is washing down into the oil since its not firing at all. 
Im thinking a valve problem or a cracked ring.  Dont think its a 
delivery valve.  While running loosened line #1 at the pump and noted 
amount of fuel that squirted out.  On #2 etc, same amount.  So that 
unscientific test seems to say thats OK.  I pulled the valve cover an 
cranked it over and the valves seemed to go up and down near as I can 
tell.  So what do you think is causing this chugga chugga?  Im thinking 
just pulling the motor and dropping in the other motor/trans I have and 
be done with it.  Just wanted to see what was up with this one first.
