one other question if one is stuck open can it be fixed, i am asking to see if i can reuse the bodies with new 100hp nozzles?

Yea it can be fixed they will stick because either the poppet valve has to much wear or a piece of debris got lodge in it. it only take .009'' size piece of debris to make it stick. But if you swap the tips to 100hp you need to send it off to get the correct pop pressure.

yeh i was going to take them to an injector shop and have them put on and cleaned but i might just save and get full injectors.

Ok I've got an update, I put the dye in and changed the injectors and found the dye in my coolant and oil. It sounds like my head gasket is bad, or worse the head cracked!:dang: hoping its just the gasket!

Proably just a head gasket unless you run your truck realy hot, if you pull it off make sure its not warped. But what did you put the die in?

I don't drive it real hot my quadzilla is set to defuel at 1300 degrees, and I put the dye in my fuel system, and I saw the die in my oil and antifreeze.

well you can get a compression test done to see which cylinder it is but guess its the head gasket

so a compression test would be able to tell if my gasket is leaking?

You can have a coolant pressure test done to see if you have a bad head gasket( or the oil cooler but then their would be oil in your coolant) the compression test can Issolate which cylinder is leaking.. I should have wrote more yesterday, got lazy on ya..

Thank you very much for all the help, Im going to try and work on it next weekend and find out for sure
