Vs l67 rattle high rpm

It rattled with the single row timing chain as well and when I installed the double row I installed two gaskets because of the clearance issues.

Thanks mate.

So does the rattle goes away with the blower disconnected?

Yeah doesn't rattle with supercharger belt disconnected

Probably coupling in the SC or something in the SC.

I would try revving it with the SC bypass valve manually opened and see if it still makes noise. That will still let the SC run but without load on it.

Could be the valve that is rattling, have seen pics of those well worn in the bore.

I tried another complete supercharger with a new coupler and the rattle is still there.
