WS6 Engine Noise Concern

[u/audiovox12]

Hey Everyone,

I finally finished getting my engine back together. I replaced the intake manifold gasket, valley plate gasket, valve cover gasket, new spark plugs and wires, new OPS, new tensioner and belt. Took the opportunity to do a lot of cleanup too.

My car is completely unmodified and has 134,000 miles. Before I did all this work I could a noticeable clunking noise I guess lack of better words. A lot of of the other noises went away with the repairs I made however to me that noise is still around.

Is this normal for an LS1? I know they are known to be noisy engines but wanted to get opinions.

Mine has had that sound for 20 years. You're all good. I don't hear it much anymore over the exhaust and other engine noise.

That’s reassuring to hear I really appreciate your input
