Howdy. First time poster...
I've been having problems with a coolant leak in between the intake manifold and supercharger on my Series I L67 from a '95 SSEi. The intake manifold and supercharger came from the same engine (which was supposedly in good running condition). I picked up a gasket from Advance, which is pictured below. I tried the Advance gaskets twice, which leaked A LOT of coolant into the intake. When I removed the */C, there was a pool of coolant in the manifold. Tons of white smoke. It backfired once and there was coolant up in my cone air filter. There'* been a trickle of coolant between the two, under the throttle body.
I was thinking that Advance was giving me the wrong Felpro gasket, so I tried one from a local GM dealer, but it'* designed exactly the same. To me, it looks like coolant in the cavity in the supercharger (and a tiny one in the manifold) is leaking into the boost valve area. I've tried it both with RTV and dry. Surfaces are smooth. I've checked for cracks and warping. I prepared them to be near sterile.
Tonight I made my own gasket, but I can't get the car to run for over a few seconds and still getting tons of white smoke. I haven't checked to be sure if its leaked with "my" gasket but I have a good feeling it is. It has NOT leaked from the rubber O rings (which are also new, came with the Advance gasket).
What do you guys suppose is wrong? Thank you.
