2002 envoy slt, enging is toast, trans and all accessories including ac are good. (well the blend door actuator for the drivers side is bad) I had the engine replaced in my sons truck 4 years ago with a 100k 4.2 I found at a salvage yard, was able to get the engine installed for $500 (cheap right) altho the guys that quoted me that said after this one they would never do another! In any case the wp went out and my son was stuck in traffic(work zone) with no exit on the hw so he drove it to an exit. Of course the head is toast at a min. Wife wants me to find another engine and I am ready to give up... what would you do?
