2003 CTS "Ebony Maria" 2005 Cadillac STS "Grace"
well this ? is for the motor heads in this forum. as some of you know i am trying the unthinkable of putting a 3.6L in my 03, but i have done some work to the heads on the 3.2L engine that came out and since i am currently playing the GM waiting game on some certain parts to finish the complete swap, i am going to put the 3.2L back in for now. i was wondering has anybody that has blown a head, or even so cracked a head or anything of such nature and put it back together, have you used copper coating on the head gaskets? i have the complete DIY manual on basically how to take the car apart down to the smallest piece, but in the section where it talks about doing this paticular job, it doesnt say that you should or shouldnt do it. so i was wondering if any of you have or havent used it...
