Hey guys, I just wanted to come back to this thread with a question.

I found a 2002 5.3 w/harness and sensors for $185. However, the guys selling says the oil pump went out and it has lost compression and needs rebuilding. He also said no crack heads or block. When an engine loses compression, is it because the rings are bad or what?

What do ya'll think?
