LS1 Piston Slap..... |
Subject: LS1 Piston Slap..... by Ultraman on 2011/7/28 15:40:51 My C5 is making noises in the engine bay when I first start it up. I have deduced that it is piston slap. It goes away when the engine warms up. I did some research on it but never did come to any conclusions. I am not worried about it only curious what causes it. What info does the Guru have? |
