Oil Pan Gasket

What are the best sealing oil pan gaskets (sides/front/rear) and what are tips/tricks to dropping, installing and sealing oil pan?

In searching 3 vendors to buy new gaskets I find 4 types being sold:
cork
paper
rubberized
rubberized cork & telfon packing

Which works best?

My ’30 A oil pan leaks excessively from right rear corner, tightening pan bolts slowed it but still 6 drops per minute with engine running….I can see it leaking from pan/gasket mating surface…running down inspection plate to cotter pin and then dripping.

Thanks, Clem
 
The cork on the rear of the oil pan fits in the groove in the engine. The seal is way too long. I cut it shorter but still with a overhang of 1/8" too allow for any possible shrinkage. I place a small glob of permatex on each side of the seal as well where if meets the flat oil pan gasket.

Call me old fashion but I use cork and a THIN coat of permatex #2.

I turn the wheels all the way to one side to get to the front and I use a threaded rod to line up the holes in the pan.

I stick the gasket to the engine and place the rear seal over the flat gasket.

I also use a cordless drill with an extension and a socket to put on the bolts then a 1/4 inch ratchet to tighted because I'm too lazy to use a ratchet for all of them to start.
 
If you put the cork rear gasket in a cup of water. Curved around the glass on the inside. then microwave it for 5 minutes it comes out nice and curved. Then it isnt such a ***** to glue up there.

I've used both cork and rubberized cork. Be sure to seal the rear cap and bolts, and don't forget the gasket between the block and flywheel cover. The side gaskets go on first, then the end gasket fits over the ends of the side gasket. As mentioned a short soak in hot water will soften cork so it can be curved into the rear main cap slot. I put a thin coat of gasket cement on the side gaskets to hold them in place, especially when working upside down on an installed engine. A light coat of grease on the pan lip will help it come off easily.

On the rope seal I tuck it into the slot and form it with a large socket the size of the pulley shaft, then squirt some oil on it and apply a good amount of grease to it. I usually have to cut some off the rope ends, but leave enough above the gasket so it will compress. I cut the ends before I oil and grease the rope.
 
HAs anyone used the new self sealing oil pan gaskets? It says dont use any additional sealer ? How do you install these?
 
Since you have been tightening the pan bolts to try to solve the leak, you may have distored the pan rail. Check it for flatness while it is down.
