After failing emissions here in Phoenix with an opacity value of 42 %(limit 40),I opted to replace all 8 fuel injectors with stock ones offered by JK at Kennedy Diesel.
Install time was as follows:
Turbo side: 3 hours 15 minutes
Drivers side: 1 hour 10 minutes
My 30 MM axle socket was sufficient to access ALL injectors and exhaust manifold (turbo side) removal was not required.JK's clipless return line kit is a MUST for this job.As per JK's advice, I attempted to fire the engine with no bleeding of the lines.The first 10 second crank attempt yielded no life from the engine.The engine fired on the second start attempt, ran roughly, then smoothed out within 20 seconds.No leaks from the engine noted. Took the truck to Lou Grubb Chevrolet to have injection pump re-timed. After picking up the truck, I drove immediately to the same emissions station I tested at before and obtained a free retest. With $455 in reciepts, the retest was free.
($355 for injectors and return line kit and $100 in timing reset)The truck passed, with an opacity value of 6 %, a reduction of 36 % from before. It starts, idles and generally runs better than before. I never really thought it ran that bad to begin with. Now I can get my plates.Whoo Hoo!!Wanted to let all those who read "Emissions Woes" as to what the outcome was.Thanks to all who offered advice in the earlier thread.
