Best replacement plenum??
Iam getting ready to replace the plenum and gasket on my 1996 Olds 88 LS. Had the system pressure tested...coolant is leaking at the plenum.
I am wondering if there is a replacement plenum that seems to be better than the others...or if there is one that has addressed GM's issues?? I have read that GM reinforced the newer ones but wasn't sure if there is a better one out there. Please note that I am not touching the lower intake at all. Not leaking there so I am leaving well enough alone. The car only has 46k original miles on it so I want to catch this leak before it gets much worse. Thanks in advance.

Re: Best replacement plenum??
The Dorman manifold with reinforced failure prone areas seems to be the most popular on the market, I have used quite a few in the shop. Make sure you retorque the lower manifold bolts, though.
