DIY Injectors

I am trying to decide whether or not a DIY injector kit is the best route for me. I have no problem doing things myself. What I am trying to figure if my injectors might need machining to restore back to specs. My truck has 200000 miles and I was planning to throw in some knew glow plugs in and I figured that would be the best time to mess with the injectors. My truck runs fine, and I would figure at most my o-rings are getting weak, but right now I think my injectors are working fine. I want to avoid the wait and core charge crap involved with rebuilt injectors thus the appeal of DIY, but at the same I don't want to crack an injector open and find out I need new plungers and some machining. What do you guys think. People who have done DIY kit before I greatly appreciate your input or any input for that matter.

Also if I went to stage 1s would be best just purchase the modified intensifiers?

I did the DIY's on my truck and they are AWESOME! The truck had 146,000 miles on it when I did the job and it was a mint running truck before and it's mint now. The injector build is fairly easy as long as you do your homework and carefully look into the injector building process that way you know what your getting into. I took my time and went thru each injector slowly and the entire job took like 12 hrs total. I would definetly do it again, it was a totally positive experience, it went great. I didn't do any machining to my injectors, they were all within spec. If your confident you can do the job and your injectors are good now, then I say go for it! Your truck will be so mich more fin to drive with a set of stage 1's or 2's.

Did you go with a DIY kit from Rosewood Diesel? It looks like they have a pretty good setup.

Ask Jim if he has a set of cores. Ask him to build them and send them out to you and you send yours in.

You can give him the core $ or ask him to hold a card # until he gets the cores.

That way you can pull your injectors when his get there and install the same night and then ship yours out.

That sounds like the way to go, I decided to build my own, but this way sounds much easier and the little extra money is probably worth it.

My truck needed injectors... so I bought them and had only a 2 day down time since I parked the truck b/c of its tapping.

I ordered the pre-machined intensifier pistons and a spare parts kit with my stage 1 DIY kit. It took me about 12 hours to get the old injectors out, modified, and back in. I also had to swap the turbine housing back to stock, which took about 2 hours.

My truck had 175K on it at the time and the armature clearance was almost like new. New are .0040" and mine were all around .0035" or higher. If you run across a bad injector, you could just get a new one locally and then modify it.
