Ls1 Knocking So I'm not exactly sure if this is a common problem with the ls1 but when I go to start my 00' T/A when its cold I end up getting this knocking sound but then goes away after about 5 minutes. My dad who used to own an 04' GTO said he had the same problem.
When my car was on the lift getting a new muffler put on, the knocking was coming from near the oil pan and was extremely loud.
Has anyone experienced this, or could tell me if its something I should be concerned about? Thanks.

mine did it on my silverado ss with a lot of mods. almost sounds like a bad lifter but when it warms up it goes away. my ws6 does it as well. dont worry. if it continues and increases in noise after a while, it could be a bad lifter if it progresses.
