Big sticker on the plug that says 19ft lbs.

Well, where I am now is that it's stuck in place. So assuming it was over torqued, it didn't break then, but now the allen head stripped and I can't get it out. I'll have my indy weld a bolt to the drain plug. Hopefully that will allow him to get it out.
But MAN, it's in there tight! I recall using a torque wrench during the last oil change to install the drain plug (first time in my life, ironically enough!) but I assume I must have used 37ft/lbs not 19.

I have found over the years that I really need to be careful with loosening and tightening the drain plug. It is aluminum(plus) and I found if the wrench end is not fully seated and a straight pull I was buggering it up a little each time. The hex socket used is only for the drain plug so it is in good shape. I bought a new plug and am more careful now...still... I have read several reports of how people have had luck getting broken ones out so maybe do a search.

My biggest concern is the dealership - I have to explicitly tell them 19 ft-lb every year it goes in for its OPC service.
The 6 monthly service I do myself
+996 on being careful I can see the potential for deforming it if you're not...

Old thread but similar problem with my 8mm magnetic drain plug. I went to change my oil and stripped the hex head hole trying to REMOVE the plug. I can only imagine that I over torqued it when installing. I recall using a torque wrench to do it by the book, but now that I see there is a different spec for the LN plug vs stock, I don't recall which one I used. Based on the stuck drain plug, I guess I used factory specs. Now i'll have to have my Indy get it out. Maybe he can just weld a bolt to the drain plug and get it out without having to drop the pan and drill it out, or worse, replace the pan!
Do torque specs come with the drain plug? I don't recall.
Charles, any chance of sending a replacement plug? I'll contact the shop Monday.

As another poster stated, the biggest issue we see are people using SAE size hex, worn out 8mm hex, or torx to install and remove the drain plugs.
The easiest way to remove it is to take a torx bit, whatever one is just a bit too large to fit, and hammer it into the plug. Otherwise, an ez-out can be purchased from various places that will bite into the hex and allow you to remove the plug without any issue.

I put in one of these several years and many oil changes ago & wouldn't have anything else: https://www.ebay.com/itm/Porsche-911...ss!25064!US!-1

There are so many alternatives to our plug in multiple colors, most all made in China, or something that just happens to fit this application. We make the drain plug right here in Momence, IL. After it was knocked off by one aftermarket parts company, like several of our products, now there are many people duplicating it, however it's not the genuine article and there is a difference.

We started putting the torque spec on the plug with a laser last year to try to address this issue.

I also had one strip out on me last week (3rd oil change since I got it). I had bought a fresh 8mm socket to use and it still stripped when using a torque wrench. Maybe I need a new torque wrench

I'd much prefer a traditional bolt head. Who not?

If your torque wrench is a click type, and goes above about 75Ft lbs its too big of a wrench to use on the drain plug,
standard 150 lb torque wrenches can easily be off by 20% at that low of a range..
I invested in a Snap on INch lb and low range ft lb torque wrench for bikes and the porsche..

Also, make sure your socket is seated all the way down/up or it will twist and break as Billy noted above...

Yup, I have a small quarter inch drive torque wrench and a big half inch drive. Both always stored at 0.
