The manifold was on the car when I bought it. How do I tell if it's the original version or the V+ and is there a way to replace the gasket or is it just RTV'd under there? I've got a leak sucking air.

 

The company itself will replace the gasket for a fee if you mail it to them.
You can make your own cork gasket.
You can use permatex 1 minute gasket

You can stick it in the oven at 300 degrees. If it warps it's the old one, lol

 

Use a different gasket, cork sucks. You talking about the metal one?
