Injector help please...

[Ba2894]

Ok so ive got a 95 7.3 and recently developed a skip. Used my infrared thermometer on the exhaust manifold and found cylinders 5 and 7 were not coming up to temps. Pulled the passenger side valve cover expecting to find a problem with the uvch for those 2 cylinders. Didnt find any noticible problems. While in there I replaced all four sets of injector orings and glow plugs along with uvch and gasket.

Finally got it fired back up but seems as though the skip is still there. I was observing the oil spill spouts while running and valve cover still off and noticed oil spurting from around #1 injectors hold down...not going through spill spout. I actually noticed it when my gp relay got oil soaked.

Anyway, what could my problem be with still having the skip? I dont have a scanner, just a code reader. Oh and no codes that I can read. Also why would oil be coming out above the hold down and not going through the spill spout? Really hoping Im not looking at new injectors but thats what im leaning towards.

Thanks for any and all help

Usually if it coming out around the base of the injectors, its due to the top injector o-ring, but since you just replaced them... (unless you happened to damage some on install). You might want to check the cylinders that don't come up to temp (may have moved if the injectors didn't go back in the same holes) to make sure that the poppet valve screws are tight. You have to remove the solenoids to check them (they are under the solenoids right in the middle). Cheers!

Ok i will check that tomorrow. Got dark on me tonight. Do I need to remover the injectors again to check the poppet valve screws? What should they be torqued to? Any other things I should look for?

Thanks for all the help

No need to remove injectors (just the solenoids ... which are 4 torx screws). The poppet screws should be tight (you will know if they are loose!). They have a funky linehead type head on them and they need a special tool to tighten them. They are small and probably don't require a bunch of torque. You can sometimes get by with a 4mm socket that's been ground down on the outside. You used to be able to get replacement socket-head cap screws from Mylex that made it easier to snug them down. Cheers!
