Mr.INSANE Posted June 24, 2006 Share Posted June 24, 2006 Maybe the oil pan or block is warped? Quote Link to comment Share on other sites More sharing options...
jnjdragracing Posted June 24, 2006 Share Posted June 24, 2006 Does the trans pan still have the groves / raised areas in it? If not buy a new pan. If it does then I would buy two gaskets and silicone them together, than place on pan with silicone. Let dry, then tighten to trans but use a 1/4 drive and do not tighten too much, contiune to use the cross pattern in tighten. Quote Link to comment Share on other sites More sharing options...
strotter Posted June 24, 2006 Share Posted June 24, 2006 I, too, have struggled with leaking small-block pans. The last time I did a bottom end, I used the FelPro one-piece. It's available for all the SBC variants, has worked fine for me so far. Quote Link to comment Share on other sites More sharing options...

WickedWild Posted June 25, 2006 Share Posted June 25, 2006 Are you useing a two peice timeing chain? If so it might be the timeing chain cover I went through that one. Quote Link to comment Share on other sites More sharing options...
MONGO510 Posted June 25, 2006 Share Posted June 25, 2006 It may not be the trany pan that is leaking! Check the shift shaft seal and servo covers for seepage. Front pump gasket or seal may also cause what you describe. Quote Link to comment Share on other sites More sharing options...
dr_hunt Posted June 25, 2006 Share Posted June 25, 2006 Are you useing a two peice timeing chain? If so it might be the timeing chain cover I went through that one. I think he's talking transmission not oil pan on the motor. dipstick tube, servo, there are pressure port fittings as well, a host of things. I had one like that once I fixed one leak I found that I had yet another. Quote Link to comment Share on other sites More sharing options...
LS1 240Z Posted June 25, 2006 Share Posted June 25, 2006 thats what i dislike about SBCs, they all seem to leak around the oil pans no matter what you do.. Quote Link to comment Share on other sites More sharing options...
JimR Posted June 25, 2006 Author Share Posted June 25, 2006 ok I M TRYING THE DOUBLE GASKET IDEA let you know Quote Link to comment Share on other sites More sharing options...
dr_hunt Posted June 25, 2006 Share Posted June 25, 2006 thats what i dislike about SBCs, they all seem to leak around the oil pans no matter what you do.. If you re-use the old pan you have to take a ball peen hammer and beat the bolt hole area back down, look at the pan and you'll see what I mean. The area around the bolt hole pulls and keeps the rest of the pan from contacting the gasket. Also, silicone the gaset to the block, lightly, and the pan lightly, the end gaskets and the rail gasket are leak points as well, lightly silicone both sides and joints, should be fine.

deMideon Posted June 26, 2006 Share Posted June 26, 2006 Also.. oil and silly cone do not mix!!! I have found that cleaning both surfaces with some rubbing alcohol first makes a huge difference in getting the silly cone to actually adhere to the surfaces Quote Link to comment Share on other sites More sharing options...

JimR Posted June 28, 2006 Author Share Posted June 28, 2006 Ok I used two rubber gaskets and Its been two days no leaks. Whats nice about this Is you can tighten the bolts as tight as you want and the gaskets dont move . thanks for the idea Jim Quote Link to comment Share on other sites More sharing options...
