Default Suggestions for sealing oil leak

Hey everyone i have a dilemma. I went to change my oil yesterday after aprox 3k miles and everything seemed normal, no leaks from drain plug, the pan was dry, the the oil level prior to the change was on spot. Btw i was running shell rotella 15w40. So i let the oil drain for about 20 min on a level ground. Then when i go to put the drain bolt on, i didnt want to tighten up all the way. It was tight but not to spec.

up all the

^^ if i tightened it just a tad more it would loosen all the way. I filled with fresh batch of oil hoping the washer and bolt would stop the leak and it been leaking all day yesterday. In the night i went out and purchased a new drain bolt (m20x1.5) and the same thing happened. Now what should i do?? Go ahead & buy more oil is a must.. Should i buy a new oil pan? The threads on the drain bolt seem fine..

Did you check the threads on the oil pan?
Sounds like you stripped your oil pan, haha don't worry same thing happened to me.

You'll have three choices if it is stripped,
1. Buy a new oil pan (Pita to install and most expensive)
2. Buy an oversized plug/bolt and it will re-thread it self.
3. If you have a drill and have a re-threader, just be careful about getting pieces in your oil pan.

Check it out first and see if they are stripped before you make any choices, but the same thing happened to me.
I bought a New sti oil pan, greddy oil drain plug, Sti pickup tube and killer bee baffle plate, it is still sitting in the box and i have yet to get a weekend to do the job. (Bought it 2months ago).

Good luck!!

I think they sell slightly oversized drain plugs that are self taping at the autoparts store.

call napa and see if they carry slightly larger self tapping drain plug. I'm 100% sure that there are more places in your local area, since you are in the largest city in the US.

i wouldnt go with teflon tape, any strands can get sucked up by the oil pickup.

you can also buy a tap for the threads and see if running it through the hole will fix up the threads enough to tighten the plug down.

Just keep in mind that there are ALWAYS shavings when you cut threads. In this case, you don't see any shavings coming out when you are threading the new plug in, so guess where they are going?

Its a pain in the ass, but I'd HIGHLY not recommend cutting threads on an oil pan while its still installed. Maybe others have had luck with it, but I'd personally never risk an engine on that chance.

No one said anything about the washer. Did you use a fresh crush washer and did it crush evenly? If they don't they leak. I had that problem.

I would try the oversized plug first. IIRC the company that makes them is Goodman and they are available at your local Advance Auto.

Do NOT try and tap a larger thread. The OEM pan is just stamped and formed metal. There is JUST enough material to hold the original threads and not much more.
