No bawls when hot. Poor tolerancing on internals when rebuilt? Too much expansion and friction when warm? Just a thought to throw out there.

to motors in a row, one a 6 year old GM reman, and the other fresshly rebuilt, both with IDENTICAL problems....i think we can eliminate that thery,

it has to be one on the things that hasnt been replaced yet

IAT plugged in? Try unplugging the EGR and see what happens. All your CTS'* plugged in?

CTS'*?

EDIT, never mind i figured it out..yes three all in

FWIW, and it'* probably just the video quality, but it sounds like you also have some bad idler pullies. My engine sounded the same.

Peter...

Any difference unplugging the MAF?

worked late yesterday, and didnt have time to drive around and test. i only started the car for that vid then shut it down... i also wont be able to get to my car till late saturday of sunday some time


As for the vid Pete, the comp im on (work) has no speakers, so i cant listen to it to compare.


on a side note(most likely un related) my car seams to be running down the battery over night
