new parts new noise
Hey guys I just got done putting in a new sa gear timing set, Delphi opti, gmb water pump, and all new seals in the timing cover. I started it up and it's making a noise. The only thing I can compare The noise to is it sounds like a gear drive timing set. Is this something to be worried about? Could it just be the gears breaking in? Thanks.

I read a post somewhere of the same noise you have, that person also tried a new non GM timing set. He switched to a GM set and the noise went away. The noise is from the staight cut gears of the cam gear to WP drive gear, the gears are meshing too tight...no backlash. Gears run in this condition will overheat and wear out. The camshaft drive gears on older Harleys are the same way. Too tight is bad. Check out page 20 of the Andrews Products motorcycle catalog available online.

Fml. No change with belt removed. Guppymech I found the thread you're referring to. Sounds like the same problem I'm having. Sound is coming from right behind the water pump. I'm glad I used rtv on everything. On the plus side car runs better. Hopefully when searching people will come across this thread and make sure to avoid s.a. gear timing gears and timing sets for their lt1. I did get a set of headers and y pipe at the junkyard the other day so I guess I'll put those on and get rid of egr and air since everything has to come back off and I'll be waiting at least a week for parts.
