I'd drop the pan for that one and use a regular tap. You don't have a lot of room for error and I wouldn't trust a self tapping bolt. Install a stud if you can, that's what it should be and it will prevent it from being stripped again.

K now im grasping at straws but what about a 3/8 self taping bolt? I only ask because to get a tap in that hole is a lot of work to be wedged between oil pan and fly wheel any other ideas r welcome

Finally got a chance to adress stripped bolt hole and found other rear seal bolt measures 5/8 from washer to end it looks newer but it fits tight is it hitting internal parts or long enough to grab a few more threads? The other bolts measure 1/2" from washer to end and they dont bite just spin . What do you think , is 5/8 to long or can it get another to fix " stripped bolt hole" i had to begin?

You might try a LEFT hand drill bit (1/8-5/16) avaliable from many hardware stores. Use a reversable drill in the counter-clockwise direction. If the drill catches on the remainning bolt piece it will often simply un-screw the piece. Then you can put a new bolt in with sealer. If not, then you might try an easy-out in the hole and remove the bolt piece.

Sometimes you can rethread a coarse threaded hole to fine in the same size. Or replace try a slightly larger metric. Chuck

the 2 centre ones at the back of the pan screw into the rear main seal retainer, as john said they are both open holes into the crankcase, if one is missing it will leak out of the bolt hole, i use permatex gasket cement to seal the bolts, it does'nt dry hard so getting the bolts out again is no problem & ive never had a leak out of them.

Bolt is very rear near the center by trans how do i tell if oil is leaking from hole or passing by the gasket or does it even matter?

Also when i tap and put new bolt which sealant should i use
