hey all.. need ur opinions cuz i really do consider them.... my friend 66 coupe with a 302seems he kept changing the gaskets over and over because of leaks.. i use to that have that problem as well....i told him to change from cork to the one peice rubber one .. the ones for lik 30-40 bucks. and put some silicone on it.. that way it wont leak anymore.... good advice?.. anyone else do that too?

One piece rubber is the only way to go.

but see we did that also.. but it always seems to leak on one corner ...like if his pan is crooked or soemething.. should we jus silicone it allll up?

Cork gaskets are good as long as they're properly installed. Personally, When I was doing heavy engine work, I preferred cork over rubber. Put a dab of silicone in the corners where the front/rear and side gaskets come together.

Everyone has there own way of doing gasket installation. My way: You should glue the gasket to the pan with all of the holes lined up and let it dry (3M weatherstrip adhesive (Gorilla snot) is a good glue to use). Then before you mount the pan to the block, a light coat of axle grease to the cork (some prefer silicone here too) and then to the front and rear seals and dab of silicone at the junctions. Install the pan and just barely snug the front and rear bolts, then tighten the rest of the bolts from the middle out in a circular pattern until you get to the outside edges (front & back) DO NOT OVERTIGHTEN the bolts. Go back thru again using a 1/4 drive socket and rachet ( this prevents you from laying too much torque into the bolts) make sure all are a little tighter than snug but not enough to deform the gasket. Good Luck

also check to see if the pan has streched where the screws go in... if the pan has a ~~~~~ lip on it, it will not seal properly

Exactly! You may need to flatten out the pan lip around some of the bolt holes.

Good catches.
To flatten the holes, take a small ballpeen hammer and using the round sideas an anvil to flatten hit it with a bigger hammer. or if you have a peice if round stock or large punch or bar about 1/2 to 11/16" to hammer on.

amen ,,,good tips on the "glueing stuff" and just like the valve cover ,,,if you over tighten/toruht? it you'll bend the lips and such and cause a leak and no amount of sealent wil stop it,,,as ya know or will know,, some stuff is pure art forum/feel and some stuff is straight up numbers
