stripped oil drain plug

[Loperamide]

Any ideas on how to take out a stripped oil drain plug (stripped inside allen hex and outer socket hex)

[andrewwynn]

I usually start with hammer in a torx bit that is big enough to cut its own groves. Then use impact tool. I have nearly 100% success with this method. CW a couple taps to help break the seal.

If that doesn't work drill out and use bolt extractor. Use right angle adapter when drilling or you'll get a drill full of oil.

Draining the pan will remove any drilling debris.

Thanks for reply. Would you happen to know the part number for a new bolt?

Use real oem and your VIN to determine. Get an oem bolt from fcpeuro etc

Because BMW

Looks like 11137568309 is the new new one.

If you look at the differences between the vehicles listed for the two, 8309 includes the LCI models.


As per realoem:

Supersedes:
11131742994(05/22/1995 — ), Exchangeable retrospectively

11131704397(04/18/1994 — 05/22/1995)

I should add that the important part is the M12X1,5 which hasn't changed.

Only one came out to a product on fcpeuro so I'd go with that one.

Use Impact. I've very rarely had any problem. The stripped bolt in this case is hex not torx. Pounding a torx that is a tight fit will turn the rounded hex into a working torx.
