I parked my car at work (Jeep XJ) for a long weekend, and when I came back I saw an email informing me that there was something leaking from it. I recently changed the Transmission fluid, but it seems I overtightened the plug, and broke the weld on the inside of the pan holding the threaded bung on, so the bolt can’t be tightened and just spins in place. I ordered a new pan+gasket (I don’t have the tools/skills to reweld the bung), and shoved a catch pan under it to catch any more leaks. Is there any type of epoxy/putty I can slap around the plug as a temporary fix for piece of mind while I am driving it home to replace the pan (Won’t be in for a few more days)?

Used it on my oil pan when I had a puncture. Stayed for about 3 weeks until I could get a new one.

How fast is the leak? This might be a “wash down and goop with Black RTV” deal.

Hard to say, but It has been there for 5 days and doesn’t seem to have lost anything over half a quart, probably less (AT dipstick is still reading well into the “good” range.

Is it real wet/dirty around the plug? If you go JB weld or Steelstix you should probably rough up the surrounding area with 60 grit sandpaper or so to give it some bite.

I used some white John Deere RTV stuff to plug up a striped oil drain plug. the car is just for blasting around offroad so replacing oil pan doesn’t seem worth it. It kinda works but if the car sits for awhile, as it often does, it’ll let the oil drain out.

That’s something I didn’t think about. My oil pan was dented to hell so the Steel Stik had a lot of room to grab.

As long as you are imminently replacing the pan, which you are, this RTV solution should work fine. Hose down with brake cleaner, rough around area with a little coarse sandpaper (give the RTV something to stick to maybe), and goop up with Ultra-Black. Skip the ‘universal’ RTVs and get the Permatex stuff. Not much more expensive and it works.

It’s all in the prep. If you can clean the surface and keep it clean long enough for the epoxy to adhere, it will hold. The fluid in the pan is not under pressure. But the adhesion won’t work if there is a film of oil in the way. It’s got to be clean.
