Mine did the same thing, I ruffed up the washer and oil pan with 600 sand paper and really tighten it down, so far so good.

 

I use a fiber/card board ?? type of washer (from Auto zone) works fine. Just get a new one every other oil change

 

Leak

1. It may not be the plug. I have seen them where the weld around the bung was at fault. make sure the pan is not cracked right around the bung. Could be a miniscule little crack. If it is leaking that much, you should be able to warm the oil up, wipe it dry and then watch it for 10-15 minutes to see where the leak is.

2. I always had the best luck with the copper sealing gaskets since they don't squeeze out but conform to the shape.

3. Get a kit that glows when you put a black light on it to see where it is leaking.

Make sure it is the drain plug and not the oil level sender area if it is a stock pan. It will run down the side of the pan and off the drain plug when sitting still.

Smashing the drain plug into a speed bump has made mine leak.

 

Contact surfaces

Before you go and do some time consuming and expensive things, I would very carefully check the contact surfaces on the pan/plug. The slightest imperfection can cause the minor leak you describe.

Remedy is to very carefully use a file to remove any burrs, etc., and make sure that the surfaces are completely flat. It may only take a few passes with a file.

 

Thanks for the suggestions, guys. I'll dress up the sealing surfaces and us a copper washer first and see if that works.
Thanks,

 

The best seal I ever used were the old sparkplug copper gaskets. Of coure they are hard to find now.

I had similar problem with magnetic plug, the threads were just too short, changed back to std plug with washer and no problems...

 

I used a THIN coat of RTV.....no problems since.

 

Can you use teflon tape? As long as you just keep it on the bolt head end, you wouldn't get any into the pan, and it might make a better seal.

 

I used a thread sealer on the drain plug of the Canton pan on our car along with the original copper washer and it worked. The copper easher alone had a slow drip to it.
