Yes, they do.

 

[FJL40]

Yes, they do.

I know this seems like an obvious question, but I don’t see one on the drain bolt. Factory forgot it? No oil leaking.

on some vehicles the washer gets stuck to the bottom of the bolt making it look like just a bolt with a thick base. Maybe its this?

on my 3.6 no, and it's 1/2 in not 13 mm. factory drain plug has some sort of gasket material on it.
I'm currently running aftermarket magnetic drain plug with copper washer.

No they do not

No, no crush washer. Here is a pic of the drain bolt. That round metal, thick washer affair at the base of the bolt is not a washer but part of the bolt itself. Now, this thick metal washer may have some type of press fit insert of sorts (hard to tell by looking at it) that is not removable..

Also.... the oil pan drain bolt is not magnetized.

Awesome! Thank you! I got worried for a minute, but good to know it’s intended to be this way. Would it hurt to put a non-metal crush washer in between for insurance, or does this bolts seal remain good for a long time?

If it ain't broke don't fix it .. Another words NO, do not add a crush washer. As designed ... per FCA, no crush washer.

Most of the modern vehicles have a rubber O-ring in the face of the flange on the bolt. I don't recall if that's the case with the Jeep. It's been a while since I changed the oil.

Crush washers are easy to source (auto parts store, eBay, etc). They serve an important function and are inexpensive when purchased even in small quantities. Better to use the right part for the job.

The seal at the drain bolt is rarely a problem. I would recommend that you get your bolt tight enough that it won't vibrate itself back out, I've seen that happen although in that situation there was some suspicion of vandalism. My father owned a garage for over 60 years and I've seen a lot of drain plugs.

I bought a drain plug from the dealership and it had a rubber like material bonded to it. Yes, they have a seal to prevent the oil from leaking.

Yes, they do.

Yeah, my forgetfulness. The first thing I do with every vehicle is toss the factory plug and install a Gold Plug which does have a crush washer. I use copper ones.

I forgot I changed it...lol
