JUNKYARD ENGINE BLUES! HOW TO DO A COMPRESSION TEST ON A GM 3.6 LITER V6 ENGINE OR ANY ENGINE!

In this video I discuss how to check for engine compression on a GM 3.6 liter v6 engine. Or any engine from a different make and model of vehicle. I further shed light on an engine that I purchased from a salvage yard to put into a vehicle that will be for sale soon. The engine that was being tested for compression is a GM 3.6 liter v6 engine that came from a 2005 Buick Rendezvous that had 82k miles on the odometer. But unfortunately it has zero compression on cylinder #5 and the remaining 5 cylinders had compression of 150-155 psi. I hope this video helps. Thanks for watching
