A properly running ZR1 will easily pass the "Nickel Test".

It could be air getting by the 2' TB butterfly (which I suppose amounts comparably to a vac leak), but not entirely the same.

Cut a gasket withOUT cutting the 2' holes, to re-check idle quality. I did this, and idle was rock-steady. I'll put it back in, when I learn coding.

What would this prove? If it does prove anything how can it be fixed?

Re: Pulling the Plenum for the first time...

For starters, it can show that you have no vacuum leaks ELSEwhere, and that you have everything ELSE in perfect tune order.

Did in my case anyway.

Fix? None yet...

What are the PCV rubber pieces part numbers? Will Jerry's Gasket be the best place to get these kinds of pieces?

See if these are the PCV rubber parts you want to replace.

Looks like the parts list is growing. Who know Corvette parts were as expensive or more than Porsche parts...

My wife is rolling her eyes now for encouraging me to pick up this beast. I have a torn apart motorcycle in my garage and now the ZR1 has taken over my "project focus".

What is the best place for vacuum lines and rubber fittings?

Do Vitton gaskets really make a big difference over Buna gaskets? Can o-rings be sourced at the local auto parts store or are they specific to the ZR1?
