Where do YOU buy a crush-washer of the type you're describing?

Subaru still uses them. In fact, IIRC, that's the first time I heard the term 'crush washer' so naturally that's what I think of when I hear it.

I always thought they used brass washers on banjo bolts and the like. Maybe it was copper, or a copper alloy that had a brass color.

....My point was only that LN lists a torque spec in their instructions.

The torque spec is there for a reason. The reason being that if you OVER torque their magnetic drain plug, the magnetic insert will “spin” inside the plug body and you will develop an oil leak.

That is why you SHOULD use a torque wrench EVERY time on the LN magnetic drain plug. The other issue is that their drain plug has a LOWER torque spec than the OEM drain plug.

So, you have a tool that can tell you exactly what the torque is. It just seems logical that you would want to ensure your car doesn’t develop an oil leak.

As far as the crush washer, well....yeah, you should use a new one every time. The idea is that they CRUSH upon use. So logically, you want one that has not been crushed when you replace it.

Crush washers are less than a dollar each. When you order an oil filter, order a dozen crush washers and you are set for years.

It’s really simple.

My point was that if you invested in a Porsche, invest a few bucks on crush washers and a torque wrench and keep her happy.

That was all.

The cost of ownership includes service.

It’s like guys who buy Mustangs and complain that the rear tires cost $200.

Buying a “cheap” old Boxster gets real expensive if you don’t properly maintain her.

That is what my “washers are cheap and engines are expensive” comment was all about.

Cheers, everyone.

Enjoy the drive.

As this thread has demonstrated, we don't fully agree here—I have had/used the LN magnetic plug since Aug, 2009, and have never once used a torque wrench on it. And I do think I've kept my machine "happy," notwithstanding having recycled a few crush rings.

That said, I do understand, and respect, what you're saying.

Cheers as well. I will enjoy the drive, have been for 14 years...what's not to enjoy??

Watch out for the cops.

And that's not necessarily a bad thing. Can you imagine how boring that would be?

I respect everyone's input here, whether I agree with it or not. And I can take (and throw) friendly jabs here and there. But I have no personal animus towards anyone.

Right back atcha: Cheers all!

.....we DO get along.

No animosity here.

Every once in a while somebody loses their mind. But that is really not very often.

I have learned soooooo much from this forum. I just try to pay it forward when I see a post that I have personal knowledge about.

Cheers!
