My first rebuild
#91
I don't know if you could. Although I'm don't really think the retaining compound would hurt anything. I read a thread in the 99-03 forum about someone having to do a couple of cups multiple times and the problem was in the prep work. I'm glad my heads were on a bench for this

hey nick - great pictures and beautiful country, there.
I'm trying to get back in the game on my engine rebuild and truck refresh and had some questions on the injector cups for you (and all the other experienced rebuilders out there). I guess I'm really just refreshing my engine, and more rebuilding the truck... anyway, the engine at 200k miles and had no issues prior to me pulling it from the rusted, beat up truck it was in previously (which I owned for the last 20k miles of its life). I checked compression and all was fine, so I'm leaving the heads in place, doing e-fuel, bigger injectors, HPOP, turbo, etc.
my plan for now is to leave the injector cups as is and just deal with it later if they start to go. I figure, since I'm not pulling the heads, the only advantage of doing it now is not having to lean over the fender to do it - as you point out, I really wouldn't be able to clean any better than later.
so my question is - do you have a sense for how well seated/tight all the old cups were relative to each other? or was there any way to tell how much old retaining compound still remained on them? from the one picture it looked like it had been 'washed off' of one side more than the other, but that could just be camera artifacts.
also, forgive me for not searching back through your thread, but how many miles were on this engine prior to rebuild?
thanks!

I couldnt really say if there is a way to check the cups. I just pulled them out. It was one of those things I really didn't want to have to deal with in the truck and for the price of the cups and rental tool I figured it was a good time. Also I think the cups crack before the retaining compound breaks down. My truck has 440,000 kilometres. About 275,000 miles. It had one scored cylinder which I wonder if it's from the age cold air intake. (Truck came with it). I'm gonna put on a 6637 before I start the truck

I got to re assembling the bottom end last night. I started to lay everything out and noticed that I am 1 second ring short. S*#€. Aside from that I did still get some of it together. Everything has been within spec so far. I didn't really get any good pics last night but I will try tonight.

I couldn't find any individual rings nor single piston sets in western Canada. All I have found is complete sets which are way out of my budget. With rre on right now I can't see much hope of getting anything happening this week so hopefully I can get the ring by next weekend. I've got almost everything I need to run the truck and I am being held up by a single piston ring. Seems like every time I see a bit of light I get kicked in the beans and tossed to the curb. The worst part is that every part is at least 4 business days to ship
