strotter Posted February 17, 2002 Share Posted February 17, 2002 I've assembled a few motors over the years, but with V8's I've always had a problem with oil weeping/leaking and ultimately making a big old mess. Do any of the old hands around here have any suggestions for sealing, especially the pan and valve cover gaskets? I'm hoping to be able to actually proudly open the hood once in a while, when this thing is finally rolling. Quote Link to comment Share on other sites More sharing options...
Tim240z Posted February 17, 2002 Share Posted February 17, 2002 I am yet to use them, but I've HEARD that the new one piece silicon gaskets work very well, and they have crush proof inserts in the bolt holes. Maybe someone who has used them will chime in...Grumpy??!! Tim Quote Link to comment Share on other sites More sharing options...
Guest greimann Posted February 17, 2002 Share Posted February 17, 2002 Coincidentally I asked about this same question in the beginning of the month. Search for "sealant recommendation" for the thread. To give you the short answer, GM makes a seriously toxic silicone sealer that they use in the factory for engine assembly. Get it from a GM parts counter under #12346192. I have used it, but haven't fired the engine yet to test it out. Quote Link to comment Share on other sites More sharing options...
strotter Posted February 19, 2002 Author Share Posted February 19, 2002 TimZ, where can I find these one-piece gaskets? Chevy dealer, or can I just hop down to the local Kragen? Who makes 'em? Quote Link to comment Share on other sites More sharing options...
383 240z Posted February 21, 2002 Share Posted February 21, 2002 For the one peice gaskets try summit racing if you want to use the four peice just hammer the bolt holes flat ( rap them with a small hammer on the gasket flange side to remove any distortion caused by over tightening) then install your gasket using the before mentioned sealer and tighen the bolt to 120" lbs making sure to hit each bolt 3 times you will have no leaks!!!

pparaska Posted February 21, 2002 Share Posted February 21, 2002 Felpro has these 1-piece oil pan gaskets for even the old SBC's. They have them in left and right hand dipstick, thick and thin front seal, etc. I put one on my 327. Very nice piece. No telling yet how it seals.
