Oil Pan Drain Plug Leak

[IZRSSS]

I have a very small oil leak coming from the oil pan drain plug. How can this be fixed? Does the hole have to be re-tapped, or is there something sold on the market a guy can use to correct the problem?

If it does have to be re-tapped can you tell me the best method/explain this procedure. I do not want to change the dimension of the plug (bolt).

Thanx

Marty I would try a new gasket on the drain plug. That's probably all that's wrong. Maybe even spring for a new plug.

If the threads are stripped, you can get an oversize plug for it at just about any auto parts store. HERE'S an example on ebay.

Daniel, or anyone - any suppliers/vendors out there who sell NOS plugs?

Ed - if Daniel's idea doesn't work this would be an excellent alternative. Appriciate the link!

Thanks gentlemen!

Marty go to a dealership. These things are/were used in every engine. Nothing special about'em.

Here's were I'm confussed...here is a pic of the plug I have in it now & the link shows a "NCRS" plug. I'm guessing if this NCRS plug is correct I can find one from a vette vendor? Or

I've seen several versions of the plug (yours included), so they may have been furnished by multiple vendors. John can probably comment on this.

Thanks again Ed.

BTW - This is the first time I've taken a pic of the oil pan. Never realized it was so pitted. I think I'll add this to my many winter projects already planned. Pull it, remove the paint and inspect. While we're on this topic, I might need a source for a correct pan replacement. Any recommendation  .

Marty...what type material is your gasket made from....It looks rather flimsy.  Mine is made out of white plastic of white nylon.

Almost any jobber can provide a new pan drain plug gasket that will fix your problem, from their stock (a new plug almost assuredly is not necessary if the old one still threads in smoothly)..
Milton from memory is one manufacturer that comes to mind - but I can't recall the exact 600 series part number they used for their gasket..
Almost guaranteed to fix the problem.

Dang...can't slide anything past you guys.   100% rawhide.

Thanx for the info Randy.

Usually it's the gasket, not the plug or the threads in the pan. Photo below shows the stock white nylon gasket on the left, and two aftermarket gaskets on the right; the top one is a ribbed molded plastic item, and the bottom one is a crimped steel outer with a molded silicone ring inner. The latter item works quite well.

Hi Marty,
We use these on all our cars. They are foolproof.

That's what we used years ago on all our aluminum deep sump oil pans and never had any problems. I had forgot about'em.

Marty I bought a drain plug gasket from Heartbeat city and it worked great. Mine also had a slight seeping from the drain plug, installed a new gasket and problem solved.
