Engine oil plug not tight: Dealer
I changed my oil yesterday mid way through the BMW service intervals as usual. When I tried to loosen the drain plug I was mortified to find that it wasn't even tight which caused me to look closely at the plug. The BMW dealer tech didn't even add the new copper crush washer. Beware of the dealer.

Fortunately it didn't leak. I think it was probably a little bit tighter after the oil change. I believe since the crush washer was ommitted it loosened up over the last 10 months. Of course that's just a guess.

Drain plug torque specs is like 25 nm (18 ft/ pound of torque)
So it's not supposed to be super tight And this torque do not crush the washer, i changed mine of course but old one didn't look used… |

If you do not change the crush washers they can leak (because they can't compress down any more to form around the drain pan and bolt head to plug up any gaps), and this causes owners to tend to tighten down the drain bolt a bit more to try and stop the leak. This over tightening of the drain bolt is what normally causes stripped oil pan threads. So never ever reuse old crush washers...

That is actually not a problem. Maybe tech was just but more careful! That is encouraging.
Now go to Jiffy Lube and let us know how you feel when you try to unscrew their "work." |

On the plus side, this ought to mean they actually change more of the oil, and there's less chance of overfilling. But yes... Last edited by M Fifty; 06-12-2022 at 03:19 AM.. |
