I think the root of my troubles lay in most of the injectors having to many miles on them and just plain warn out(211K). What are my options if I decide to just change all eight out? Price?? Can these be sent in somewhere for rebuild?? This truck is hard starting when cold and after running only hits on a few until warmed up. Runs good after warm.

Thanks

If you want check your injectors you can measure the armature plate clearance with a feeler gauge while still in engine. This will tell you if the wear is down to under accepted spec. Simple to check once the valve covers are off. Post back if you want more details.

You may just have glow plug issues also.

Yea, I guess I should check them before spending all that green. I've been through the glow plug circuit from one end to the other, new glow plugs, checked circuit out with clamp on DC meter and that part is working perfectly.

This truck is growing on me so I'll keep it for a few years I just want to avoid head aches along the way. I assume Armature clearance will be the distance between what moves and what doesn't move, is the check point right there on the very top of the injector?

Thanks a million!

Hey Smokedaddy, Go to Beans diesel performance or Swamps diesel performance. (Just do a google search for either of them) They both seem to do great work and you can have your injectors rebuilt and upgraded at the same time for under a thousand.

to check aramature plate clearance you need to pull off 4 screws on top of injector and pull off the solenoid. Then pull off spacer. Now you see a square plate which is the armature plate. A feeler gauge is used to slide under neath the plate. A new injector spec is .004 in
A minimum of .0015 in is needed. If you have a .002 in feeler guage and it will not slide in that injector is just worn out.
I had 5 bad ones that would not pass the spec and I replaced all 8 injectors. My cold start problem was then gone. This was only done after doing all harness and glow plugs and relay.

Whats needs to be replaced in the injector to get them back to spec?

They need to be remachined. Read this post that Dave from SWAMPS DIESEL posted. This can cause a cold or hot problem.
Swamps Diesel educated me on this problem and I purchased Baby Swamps injectors when mine had the problem. Thanks Dave /ubbthreads/images/graemlins/cool.gif

Great info here, thanks! I may look into a rebuild assuming it's less expensive then buying rebuilts on core. I have other things to drive so I may park this beast, pull the VC's and get busy, after vacation that is...
