The head was swapped due to leaking cups and coolant getting in to the fuel. I was informed that it was more fiscally prudent to just get a new reman head than to repair the old one.

THE OLD isx HEAD SHOULD never BE REUSED, repaired, re-worked.. etc.! - A BRAND NEW ONE ONLY (not a reman) is recommended.. and of not, then only a certified reman from cummins if that is all that someone can get a hold of as a last stitch thing.


sounds to me like you have a lot more testing to do. Perform the things that I mentioned. Start there and confirm all of them!. making half-arsse assumptions is exactly why people chase their tails and waste money and time.
