Figured out why my Canton pan was leaking out of the drain plug.

Whoever welded it melted the bung surface into the weld, so there is barely any metal for the gasket to seal on. Emailed Canton, we'll see what they say.

Anyways, I guess just give your pan a good once-over before you pop it in there, I didn't see the weld damage until I had the plug off.

why not plug it and then hit it with a flat sanding surface to square it up and give more sealing surface? you could do it by hand with something hard and flat as a backer or with a small belt sander.

could try a drain pet **** and Loctite it in there. Or adaptor bushing that screw in there with pipe plug.

I agree they should remedy that. When you're in the business of fabricating oil pans, this is clearly a defect you don't want getting to your customers. Hopefully getting the pan off isn't too hard and they ship you a replacement in a timely manner.

They want me to ship it back for repair. Luckily this is a second race car, but I'd be miffed if I relied on this car more.

Got a longer bolt at the parts store, teflon taped the very end of the threads (by the bolt head), and used a composite gasket. Hasn't leaked yet and I've been driving it all week.

Glad you have a working solution.

I still don't get why you don't plug it to avoid metal contamination inside the engine, sand 1/16" off of it to a flat surface. If that fails, you can ship it back.

Good luck!

I agree, just grind it flat and use a copper washer. Should seal up fine. They should still provide some sort of credit.
