Thanks for all the interest, now for the suck news, all Delphi suppliers I use are out till at least november. The end not the first, I have 2 sets left but this last order cost me more so I have to add that, they are going from 295 to 343.00 sucks but after this I cant get any more till the warehouse restocks. And I bet those marketing genius's are going to mark up these "obsolete hard to get parts".

I agree, though with my engine apart, I decided to check mine. They are Lucas CAV BB code injectors I bought new in '98 (IIRC). They have about 50K on them. Watched them being tested and other than a little bit of chatter with some, they were all popped at 1650 psi with a good pattern and no leakage. I'm going to reuse them. Wish it was as easy testing the pump, but it has the same 50K miles and the truck was running fine before I blew that head gasket.

I guess Russ would be the guy to ask, but I wonder how often new injectors need to be tweaked?

If Typefour wants to let me us know when he gets more in, I definitely will order a set. Until then I have a clutch fan to replace, not really looking forward to that. I certainly understand him having to pass the increase on to his customers, I have had to do the same with the rising cost of deisel in florida...still can not figure out why it went up 20cents in a week.

I have yet to try it either, I have done alot of reading and it appears to be pretty straight forward. The big thing I have read is to lube the O-rings prior to installation, some say to use motor oil and others say to use vaseline, not really sure which is better. The only thing I am not sure about is the IP timing, again some say you have to adjust it everytime you change injectors and others say not. The one thing everyone agrees on is to change the return lines everytime you change injectors.

One thing that kills me is alot of these shop I have talked to around here just want to replace the bad injector(s) and let it go, they are probably the same guys that only change the bad sparkplugs when they tune up a gas engine, or charge you for putting in new ones with out even taking the old ones out.

well they do this because modern diesel's fuel injectors are very costly.with the idi though,it just makes sense to change all 8,as it's still cheaper than just 1 injector for a powerstroke.

easier than changing sparkplugs on my 93 bronco, do not be scared of this project!!! any questions, let me or another that has done it know, it is easy. oh and just simple oil for the orings, but if you have a petroleum jelly lube, get your lube on hahaha.

If you've got any issues just ask like he just said...the injectors themselves are 1" deepweel socket, the injector lines onto the injectors are 5/8's. Don't be afraid to bend the lines out of the way of you getting the injector out GENTLY. I use WD40 to lube the O-rings but oil or vaseline or transmission fluid will all work for that need. The cheapest place I've found to buy the Return line kit is from Pensacola diesel. Been there done this twice and the second time I had an issue.....feel free to ask for help.

What about having to reset the timing of the IP, is that mandatory or can you just change out the injectors and return lines, start her up and drive? I definitely plan on getting the Viton orings for the return lines when I do this.

So, when the supplier does get some in I am going to do a large buy and pass the savings on, I will post all info when I get it.
I sell them with a return kit and the vitons are included at no charge.

It is not mandatory to set the timing but it is the best way to do it, also new ones could use a check after 10k or so, if reset then they stay set for a long tome, the springs take a set after a while.

1650 on a used set is great and they will stay at that pressure for a long time. The Lucas CAV injectors were a fine product.


I am working out of town all during the week so pardon me if I am slow to respond, I get one day and the wife gets the other of the weekends.
At least I have a job for a while.
