Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I have a leak coming from the oil gallery plug located on the oil cooler mount casting above the cooler. Is anyone aware if there is a hack to re-seat or seal this plug without major disassembly? There is a constant weeping of oil from the plug perimeter, so any epoxy related fix is not possible. Also, there is no way to get a straight shot with a hammer & punch to knock it back in because the oil pan is in the way. Please help! Thanks! View is from under car, under the tip sump, driver's side, looking aft.

Well, here is my solution in case anyone needs it.... First cleaned and dried the plug with brake cleaner and compressed air. Then, I heated up the cast aluminum boss surrounding the plug with a heat gun to expand it a little bit. I then used a small pry bar between the oil pan and the top of the plug to seat (force) the plug deeper in the bore and slow down the leak. Then cleaned and dried the plug with brake cleaner and compressed air again. Next I had JB Weld Tank Weld putty mixed and ready to go. This seemed like the best choice since it gas and oil resistant. Next, I pushed the previously mixed putty into place quickly over the plug before oil would start to seep again. It sets in 5 minutes and cures in 1 hour so it goes quickly. After 1 hour, I filed it flat. The dark spots are low points my flat file couldn't reach. Finally, after the putty had cured, I mixed up a batch of Locktite 9340. 9340 has a 90 minute working time, so I let it sit for about an hour to allow it to thicken up a bit before applying it over the putty patch. It has a 3 day cure time to max strength.... and this stuff is strong. So far, so good. Will update after a few hundred miles of driving.

Looks fine to me. U was gonna suggest some ultra grey rtv but what u have done seems better.

Seems to be holding so far. This is after 50 miles. Trying to get some driving in before the next storm.

**UPDATE** Just finished a 100 mile hard run. Still dry as a bone, so I'm ready to claim this fix is a success!
