I've tried and tried to get my steel pan to seal. I've tried both rubber and cork with and without sealer. I also recenly replaced the front and rear seals, seal around the shift selector, o-ring on the dipstick tube, speedo gear housing gasket, and the tail shaft housing gasket. In the process I also checked the pan with a straight edge and dimpled the holes....then torqued to 12 ft lbs. I'll be damned if it's not leaking around the pan AGAIN! At this point I could've already put an aluminum pan on it and been done with it! Yes, I have verified the fluid is not comming from anywhere else....it's definitely pan gasket related. Time to put on a new pan.....gives me a reason to get the car off the ground and redo the exhaust, too.
