Stripped oil pan nut

[busmania]

The far rear but on my oil pan seems to be stripped. Back by the starter. Can I make this oversize with the pan on? What is the next size up? Photo below.

Use a thread repair insert.

Repair it the easy way. Different sizes are available.

are you sure that the front and rear two aren't larger than the others.

Not sure. I wondered this too. But all of the other ones torqued just fine. I could t even get this one snug.

I think that I would remove the oil pan, weld up the hole.
Drill and tap new threads. Be sure to get the location correct.
I just looked at a spare, to hard to put a nut inside.
And I hesitate to go oversize.

Possibly take out the starter and use longer bolt and a nut

Ok so I ran a tap through it (original size) and then I was able to torque it. Not sure it will hold but we’ll see. Normally I’d take the pan off and tap it correctly, but I already took the pan off once for another screw up and dont want to do it again unless I absolutely have to…which I’m sure at some point I’ll need to do at that point I’ll repair correctly next time it’s off. The first time I torqued the pan down it torqued down fine so this is somewhat strange. I tried two different bolts that wouldn’t torque until I ran the tap through.
