ok so i stripped my oil pan while doing an oil change...i tighten the drain plug to spec...but it still dripped a little...so i bought an oversized plug 3/4 M12x1.5...it worked in fine but still drips....the gasket that came with it was metal and rubber but it didnt hold the leak....best route with out spending much money because I am currently in the slow process of obtaining a new M52 motor....so i need a quick fix until then...so prolly 2 or 3 more oil changes before a new motor may be in.....I do not mind using the top side oil changer until the new motor comes in....
Please advise....I have read almost all responses and thread about this on alot of the bimmer forums....
1 JB weld with the oversized plug..
2 tap it out to 14 and use a Mercedes Benz drain plug
3 New drain plug washer
4 Loctite with oversized plug
5 new oil pan but I really do not see the point since there will be a new motor soon.....
HELPPP PLEASE __________________

Is your oil pan cracked? You can crack the oil pan if you cross threaded the bolt back in. __________________ 98 Avus Blue 318 ti Active

no the oil pan is not cracked....i am definitely using a top side oil changer...i already used it during this ordeal....as for the quick dry epoxy...any ideas on the company who makes it...or a specific one i should use. I plan on doing this on wednesday....the car is sitting in the driveway on jack stands and drained of its oil....first i used a rubber gasket but it melted and did not hold...
thanks for the info...more would be good but im up for whatever... __________________

lilflip, just yesterday I bought some waterproof, flexible two-part marine epoxy at Home Depot. It's made by the Super Glue Company. That might work for you.
I have messed up drain threads, but thankfully they weren't completely destroyed. There was just enough the get a new crush washer in there and torque the plug to spec. I haven't touched it in years, and thankfully it doesn't leak. I've been using a topside changer even since. | | | | | 01-24-2007, 01:07 AM | #7 | | TRETEN IRGENDEINES ESELS Join Date: Aug 2004 Location: Rhode Island Posts: 3,687 |

Woke up the next morning with oil all down my driveway and heading towards the sewer. We tapped the whole out put a double plug in and used an expoxy covered the crack and sealed the bolt. It's been like that for 5yrs and the expoxy is working wonders. __________________ 98 Avus Blue 318 ti Active

I imagine regular RTV(?) gasket sealer would also work as long as you can let is set up for a day.
JB Weld would be permenant and is VERY good stuff. I have fixed holes all over older cars with that (moslty gas tanks). You could even retap the JB Weld to accept the original drain plug. Have done that too (on a Ford). | | | | | 01-25-2007, 12:23 AM | #12 | | TRETEN IRGENDEINES ESELS Join Date: Aug 2004 Location: Rhode Island Posts: 3,687 |

There is 2 expoxies and you mix them together then you better put it on something before it cures. Heat makes it stronger so the first time i warmed the car up after that it was golden. I'll try and find out for you tonight.. __________________ 98 Avus Blue 318 ti Active

I'll try and find out for you tonight.. | The name is "JB WELD." I've tried to attach a picture (I've never done it before). | | | | | 01-25-2007, 02:39 PM | #14 | | Junior Member Join Date: Oct 2006 Location: No.VA Posts: 14 |
ok..so i went to fix it up...the outer lip of the threads were gone on the bottom of the hole...that was one of the problems...and above the hole it was CRACKED about probably from putting the oversized plug in there(3mm crack...good looks Tyler)...i managed to patch that up and also recover the lip with JB Weld...stuff is great.....but it still leaks a little from the crack and not from the drain plug...I also used a little permatex thread sealant...tonight im going to patch it up somemore to make sure that crack doesnt cause more leakage....other than that it worked great....with the heat it hardened much better...but while i was doing it last night...it was like 35 degrees....so it took a little longer to cure....thanks to all who helped it is much appreciated...im sure i will be on the forums more once...the beginning stages of the motor swap... __________________
