They are in the front row and the left and right bends in the oil pan, should I tap or heli coil? I know they are stripped because when I get both bolts in and rotate till they seat against the pan and block they just keep rotating the bolts are fine pulled them out to make sure.

Hank there is usually a couple of studs sticking out of the oilpump instead of bolts.

The pan itself is not threaded. Its just a hole.

Stripped holes are circled in yellow, the holes in the block are what I meant.

If it were me and the bolts around it tightened up nicely, I would snatch the bolts out silicone up the holes. There are enough bolts around it to seal it.

What about the "right" way? Ill try that first when I get everything put back together completely. But what if it starts leaking?

If you siliconed around the pan, its not going to leak anyway. Using silicone you do not tighen the pan up real tight anyway or you will ooze your silicone out. You just want to snug them up. If I were going to fix it, I would drill it out and tap it to another size. Or locate a couple of self tapping bolts slightly larger and run them up.

Have you double checked all your bolts to make sure those two holes did not have a slightly larger bolt in them and maybe you stuck them in another hole? Where two others hard to screw in in two other holes in another location?

I do not think so, though I will not rule out that possibility completley, I cant remember any of the others having a hard time going on they all seemed pretty much the same.

6mm x 1.0 heli-coils, Hank. You can install them with the oil pan installed. Just make sure to get them threaded in far enough to get beyond the recessed area on the flange. Good luck.

Checked in with oreillys today they do not carry helicoils here anymore, I dont know if they where called Kragen in your neck of the woods but ours went by that name, the guy told me when they took over they got rid of a lot of "specialty" stuff. Lucky for me one place in town has them for $39 Im gonna pick up the kit tomorrow.

Huge cost just for a couple of oil pan bolts. Tap is a lot cheaper.
