HI I'm Wayne
I will help you with this
do you have a air compressor on it
No air compressor on it>
Hi Thank you for that
Ok, no compressor, then I suggest to take the head
to a machine shop and get it magnifluxed for cracks, that you would not see
and tell him to pressure test the cups
I hope this helped you

NOT THE POOR/BAD SERVICE
here is a video on how to do it
Newer CAT engines that still used PC chambers went to a single piece chamber and you must remove it and replace the seal ring underneath it that seals it into the combustion chamber of the head at the same time you change the o-ring around the top of it that keeps the coolant in. Use copper anti sieze on the threads and clean the sealing surfaces with wire brush etc so you get a good seal top and bottom. Torque to 140-160 foot pounds. Injector hold down nut torque to 100 foot poundsRemoving PC chambers is not to be done lightly. You can take the threads out of the head if you're not lucky/living right! If it has to come out, then sometimes an impact wrench will get it out with less trouble than a breaker bar once it's broken loose. If it doesn't spin right out, then go back and forth, a few minutes spent loosening it up can save you a bundle purchasing the helicoil repair from CAT that is needed to fix them when you take the threads out with the chamber.
