FWIW - I took my plenum apart last night b/c the top exterior portion had some small hairline cracks developed and small amounts of oil was seeping out...
the epoxy is holding up perfectly - looks like the cracks on the exterior are just due to thermal cycles and the difference from the paint/plenum/epoxy...not sure how the oil is getting through - I wonder if the expoy is porous enough to allow the oil to seep through??
didn't get a chance to take any pics last night...but here's a pic of what it looked like before:
here's it unfinished...you can see the epoxied areas.
finished version
installed

i think its about time to start shopping for some lower plenums, anyone have a revup lower that they are willing to part with

Have you notice any performance increase by doing this? How's butt dyno say?

got the manifold back and grinded down the welds. I did what i cold with just sanding cuz the guy that welded it tried to fill in the gap after he had welded a round piece of aluminum, but didnt do suck a good job on that part. nothing a lil J&b weld cant fix.
Inside is better. dont know if i want to j&b weld the lil holes or just leave them though.

I did the same thing but left one bolt in the center. I think this has been one of the best intake mods I have done on my SC'd Z. I don't seem to have the torque/horsepower drop off that many seem to experience on boosted Z's.
