thank you...guess i should have mentioned that the pressure test was done, twice and showed no issues. from all the information ive been reading on the web it seems that there may have been some issues with 01's having cracked heads? i sure hope not.

if it were cracked it should have shown up on pressure test. Als check for water under truck with a/c not on as it may be heater core leak and going out a/c drain. unless the head is cracked in exaust seat area where it would go out tailpipe and you wouldn't see it.
