Stripped the oil plug, Re-tap?

Hi,

I tried changing my own oil and while I was using a torque wrench to tighten everything back up, I stripped the oil plug hole under the engine. Now the bolt wont tighten and just continues to rotate without tightening when i screw it.

I ordered a new 12mm bolt from honda and the new one also won't tighten.
I tried placing two washers and it still won't tighten, just rotates.

I am about to re tap the plug to 14mm, but wanted to ask around here for ideas before I make such a permanent "repair."

Thanks for any suggestions.

300 or 500? If it's the 500 I'd replace the pan, but i think the 300 is integrated into the crankcase? (not sure about that though) I'f you re-tap it I'd be afraid of getting shavings in the crankcase/oil pan.

If you do go that route I'd run at least a quart of oil through after you put the new plug in and drain it immediately then reinstall and fill appropriately. Then I'd do a quick change again after running for a bit.

I never stripped a bolt or a stud until I bought my first torque wrench. In recent years I don't use a torque wrench unless I am assembling an engine or transmission. I tighten everything else Good N' Tight and go for a ride and come back and check all the fasteners the I installed and if they are Good N' Tight I put the tools away.

Good luck with your repair.

If you are retaping coat the tap with grease to catch most of the metal that comes off then flush sump with some engine oil
