New valve covers...hole size problem
I am dropping a new zz4 into my 'IROC TPI 'vert.
I just had my polished aluminum valve covers delivered from Chevy.
On the right side valve cover, the hole at the rear is a larger diameter than the one in the original cover.
Is there an adapter available to connect the stock breather line to the throttle body?

In the "Help" section at most auto parts stores they have all different sizes. You will just have to go and match it up. I actually had to go do that tonight.

Ya, when I got my aftermarket valve covers, the hole was too big, so I used a stepped grommet.
