Well this sucks
I purchased this in December 2014 and have had 10-14 oil changes since then.
i did not use a torque wrench on this oil change. the head sheared off.
see pictures. The LN magnetic plug head is sheared off.







fun question:
the oil is Rotella T6 5W-40

its dripping about 2 drops per minute with engine warm and off. rough calculation based on video is 1440 drops per 12 hours or 2 drops per minute

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 ?

So you overtightened your LN plug cause you didn't use a torque wrench, then stripped it to bits. What is the question here?

Say a drop is 3x3x3 mm, which is 0.027 mL. 1440 drops = 38 mL per 12 hours. One liter after 308 hours.

Ouch!

You should be able to get the rest of the plug out with a torx socket. As already stated, too much torque. If I remember correctly, from one of the other threads, the torque value for the plug is only 19 ft-lbs.

IIRC, the plug uses a hex (8mm) fitting tightened to 19 ft lbs not a torx head. Even using a torque wrench, a torx head will eventually round out the plug fitting.

19 ft/lb according to the LN site.

I'd be thankful that the head sheered off vs. stripping the threads in your oil pan. Replacing the drain plug is a lot easier, and cheaper than the entire pan.

You have one of the earlier versions of the plug, as do I. The new ones are made differently and are stronger. If you're quick, you can probably change the plug without losing too much oil.

Dimple magnetic plug.

Expensive but a great product. I use one on my 996. Also don't have to worry about hex or torx - I think it uses a 17mm open end wrench or socket.

I suggested using a torx, because the hole is somewhat damaged. Since you don't care about further damage at this point, that is what I'd use if the 8mm hex doesn't fit easily in the hole. You don't want to force it in.

Maybe give Charles a call, he has great customer service.

great info from the Porsche Clan thank you user 63031 for the math.

I accept full responsibility for it, ive done it so many times i know the feel and it was not forced off it was ...done.. and I just barely tightened it.
yes thank you Splitting Atoms, the hex tool to extract is a good idea.
i am usually very careful and log every repair parts with pics etc.

thanks !!

Mine busted like that. Earlier model. Since been updated. Contact LN Engineering and they will send you one of the newer plugs....for free.

That's the reason we chose against a steel plug. The aluminum threads won't strip the pan out.

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.
