Im resealing most of the upper engine, all intake gaskets, valve covers and all new injector o rings. I bought all new o rings for the injectors and one new plastic cap piece that was busted. After i cleaned out all the holes really nice and put the injectors back in, all the plastic end caps cracked a little. Is it goona matter that they are all cracked besides the one? I just dont wana spend 5 bucks a piece on new ones if i dont have too.

Heres the one that was busted..

 

Personally I would spend the money and replace the tips, It is a rather cheap price to know that they wont chip off and caause possible damage to the engine.

Just mu $.02

Thats a great link.I believe with out the caps it affects spray patterns.

 

nstueve's Injector cleaning thread, or the RJM injector service page?

(definitely, or they wouldn't bother to include them)

 

Great link. Has anyone tried their EGR delete?

 

Wow that kit is awesome, ordering one now. I ordered 8 kits at autozone without the filters and it was 35 bucks! Ill return them as soon as i get em. Thanks for sharing!
