Leaking LN Magnetic Drain Plug!

From what I've read on here, it seems that there's a very narrow window between not enough torque that the aluminum washer won't seal and too much torque that will strip the inside metal from the outer aluminum threads. That's just my observation.

I would not bet on that. We have installed a lot of these plugs, torqued them to LN’s specs, and never had a problem with them. That said, we have also seen quite a few that we did not install that had become “problems”. The common denominator between the two seemed to us to be how they were installed. After multiple oil changes (which we did), the plugs we installed looked brand new; the problem plugs brought to us for the most part looked like they had been through a war with Allan flats rounded off, parts of the plug head chewed up, and some in so tight that they must have been installed with a breaker bar.

Geeeeeez, I wish I’d never stumbled into this thread.

After 11 years of virtually trouble-free oil changing experiences with my magnetic plug (sans torque wrench!) I’m just sure it’s all gonna go to hell in a handbasket from here on out.

You and me both...

All this for a magnetic drain plug on an aluminum engine block. Most people on here when they get all concerned about metal shavings in their filters the metal shavings are bronze/brass in nature (guide failure??? IDK I've never been inside a flat 6 engine).

I mean you pull your drain plug out and its covered with iron shavings; you've already had problems. Like doing 5 laps WOT and then seeing your oil pressure is 0.

Does LN supply the Porsche crush washer with their plug? If not I have I have been a very lucky dude..

I have no idea whose crush washer they use, but I have used the factory crush washers as replacements on the LN plug for years without any issues.

+1. OEM crush washers from Amazon and proper torque, which I think is stamped on the LN plug.
