Injector sleeves or cups
 

I was just wondering how important it was to pull and reseal the sleeves when the injectors are getting replaced. I have read pros and cons. Thanks in advance

well i will leave a post when im done with mine im not re sealing mine as they are not coming out when i replace my nozzels ill let you know how it turns out if that helps

Thanks
I am going to be doing mine next week and I am worried about leaks since this will be the 2nd time they have been changed. The first time was by a dealer and I don't think he resealed them. I am not even sure he replaced them all like he said since three more are bad less than 40 thousand miles latter.

wow thats rough well if you find any thing thats useful id be glad to hear from you im a day or two from getting mine done and keepin my fingers crossed i hope it works riht this is the first set ive done kinda goin in blind

I did mine in Jan. every one of my cups came out and i'm glad they did because i know they were seated back properly. Everything i read b4 i did it said if they don't come up with the injector then don't worry about them. I don't like doing thing half way and wonder if it's right so if i did it again i would pull any that didn't come out. reseating them really isn't bad I used red locktite sealant like everyone says you should get the cups in straight and with a drift or even an extension for your ratchet will do. drive it in gently till the drift bounces back with each smack you'll know it's seated. don't forget to clean the seat areas spotless b4 you reseat them

thanks for the reply veggimaxny. I agree that it would be better to reseal all the cups. My problem is what if some of the cups do not come out with the injectors? Is there some other way to get them out with out the tool that no body seems to have. Plus it is pretty expensive. Anyway I was going to buy one but the manufacturer is not even going to have any till late april or march. Too late for me.

thanks for the posts they are helpful im about to go pull the drivers side injectors and change the nozzels out:jump:boy the driver side is the tuffest to do outa the two specialy seein that ive got this dang M>S cant jump around like a monkey anymore lol

I don't know if this is possible becuase i didn't have to try, but i thought of trying boat plug.You know the Black rubber kind you stick in the hole and tighten. I wondered if you cranked it down good if it would hold on enough to pull the cup out. When i did mine it didn't take much to pull the injector up and the cup was stuck on each one. i bet it would work. Give it a try and let us know if it works. i think those things have a small nut on the bottom side so just be careful you don't loosen it to much cause the nut will fall into the cylinder you could always stick a peice of rag in there to plug the hole.

Hey thanks. Thats a great idea and I bet it would work. Anyway tomorrow is T day for tear it down so I will let you know. And thanks to all the great posts and information. It made me start to think I could do this and save a bunch of money over the stealerships.

yeah, if they dont come out i wouldnt mess with them, but if they do use a brass punch to drive them in with some red high temp loktite

:jump:ok gotten mine in on both side hower #7the cup came out with the injector and upon futher inspection it had been pulled before there was nicks and dentswere some one had driven it back in the seat i cleaned it up and i also found a tool that may be helpful to you guys its a plumers flute to seat the little rubber gaskets in a faucet i used the tool to clean the seat in the bottom of the the injector seat it got all the old loctie out of the bore were it seats to the head :rocking:it was awsome i have to get the wire harness and all the rest hooked up to get the old girl fired up hopfully tonight ill let you know if it works and works well

how did it go?

Well it took me about 8 hours to get all 8 injectors out. I had the most trouble with the drivers side valve covers. When the stealership replaced the injectors 40 thousand miles ago I guess their tech stripped most of the impossible to reach 5mm allen bolts. It was quite an adventure but I got them out. thankfully all the injectors just came out easily. I gave them a couple of twists back and forth as much as possible and they all just pulled out by hand except number 2. that one I had to use a little pry bar. All the cups stayed in place and looked real good. Just waiting on my injectors from Lincoln diesel, should be here tomorrow.

drivers side can be a pain :ouch:

injectors can be a PITA. Various 5mm allen tools are a must. When i did the set on the farsm 03 the tech who did the set before me kinda forgto to tighten a lot of bolts or just forgot them all together, the wiring harnesses under the valvecovere were all loose.

I always tell people dont fix what isnt broken. If the sleeve doesnt come out dont worry about it. Now if you are bored and own the 180 dollar tool, and want to buy 16 o rings, go ahead. But other wise its not that big of a deal.

The tool is pricey, i know it sucks, but if you do this a number of times you will want it. I couldnt live without it. Very quick process.

yes the tools are very helpful to have i made my 5 mm tools out of some old allen wrench sets i ground a ball in the tip and then cut it off to put it in a 5mm socket to get the rear 5mm bolt outa the valve covers with it i allso replaced the bolts with regular headed bolts after i got it apart i threw them damd 5mm bolt away :jump:
