I am adding headers and a corsa sport to my silverado ss. Going to run a vent line from valve covers to headers.
Question does the corsa muffler have any fiberglass packing in it or is it all just steel chambers?
I don't want oily buildup on fiberglass. Sounds like a recipe for disaster.

There is not any plumbing that needs to be installed between the valve covers and the headers.

Im running a crankcase line into the collector on the headers.

Why would you do that?

the Corsa that I saw cut apart was all metal on the inside.

You're better off running a catch can for a crank case vent vs burning/blowing it out of your exhaust

That use to be very common on old school setups to vent the crankcase in the exhaust. Only works well if you have a free flowing exhaust setup with very little backpressure.
