Supercharging (this time, it's real) in Buick Reatta Posted April 3, 2006 Philip: Did you get two new "o-rings" for those two coolant ports with the last gasket kit? If not, make sure you get them with the next kit. If the kit does not come with them, get them seperately (GM sells them). I have had instances where the coolant was able to "seep" thru the paper gasket over time. Also, in the pictures you provided I see what appears to be some contaminiation of the sealing surfaces around the coolant ports on both the lower intake and SC. If you can't clean these up, it would be acceptible to smear a very light coating of ultra-black RTV on these surfaces before assembly.
