aftermarket valve cover question...
on the drivers side there is this connection:

and on the pass. side:

And I do believe that on my 2002 LS1 Corvette that the pass. side is more than just external fittings, there is a black "device" on the underside of the factory valve cover connected to each of those two ports.
And then there's the oil filler neck.
how do you "massage" these aftermarket valve covers to integrate fully with all these connections ?
