I'll point out the factory drain plug has the same mode of failure if you use it long enough or over-torque it repeatedly. Porsche intended the drain plug to be replaced every time you change the oil, like the original housing for the filter. That said, these failures are far and few between and we'll replace the drain plug for free, even though it's been in service for many, many years, as a courtesy.
This, and the fact that Charles is active and willing to help (he has answered my PMs on multiple occasions), is why I buy LN products. Not to mention the R&D to back up solid engineering.
Kudos

Class move, Charles! To all the other Rennlist vendors, this is how you treat a customer.

I would ask that you send an email to support@LNengineering.com with all your contact information and a brief description and photos. My staff will take care of this for you ASAP.

Great customer service!

I have replaced the magnetic drain plug with every oil change since my purchase of car 5 years ago.
It was suggested by a Porsche Dealer/Service center that I trust.

Is that a safety wire hole I see?

Not on the M96/M97 plug (M18x1.5x12) - maybe on their other plugs.

It looked like one in the pictures had one, which would be cool.
But where would you tie it off?
I don't think there is any place close by.

I bought my LN mag plug in 2017. So it should be a newer model. I do 19 lbs with fresh crush washer. Seems like a small amount of force, but this thread explains why it is probably good. In addition, my drain plug has never leaked after at least 6 oil changes.

The plug I bought 2 weeks ago had a sticker on the plug: 19 ft. lbs.

Bought mine back in 2017 as well, hasn't leaked but I've had to clean it and there has been residue.

Going to check it again to see if anything has changed.

how much oil in in a drop ? which will answer how much oil will it leak in 12 hours ?
at what rate will it leak slower when the engine is cool ?
If a drop is 0.05ml, and an oil change is 9.3 gallons, there are 704,080 drops. It would take 244.47 days. Of course, you can save time by changing the oil filter housing contents while you wait.

My plug stripped the very first time I used it. It had been torqued properly too. I did get a credit return from Pelican, and hopefully they sent it back to LN for failure analysis. I had one a few years back in my Boxster, and was quite happy with it. One for 2 I guess. The LN products are generally very good. I use the spin on filter adapter, and the bearing upgrade is going in this fall (did both on my Boxster). Back to the plug - it is very soft.

Not saying this is the case with you, but we do random destructive testing on our plugs and it takes 70+ ft/lb to round them out, however if an SAE hex (or in one case someone used a torx), it will round out on the 1st or 2nd try, or if the metric allen is rounded or damaged in some way.

Let me just add that this thread is not an open invitation for people to email asking for new drain plugs for free because they want the new version. If you have a legit problem that isn't normal wear and tear, I'm happy to replace drain plugs, but no drain plug is a forever item. Just want to make that perfectly clear as several people have emailing thinking they are entitled to free stuff just because.
