Can someone tell me why I cant stop an oil drip from the drain plug?

Volvo D13 engine. Yes it has a new drain plug washer, and yes it is torque down to 45lbs as it says on the oil pan. It still has a slow drip though, about 18-20 drops per minute. Ain't much but it's 18-20 drops per minute more than what I want. I know these oil pans are the "special" lightweight not as durable oil cooling pans that can crack with too much torque on the drain bolt. Wasn't leaking before changing the oil, now it is. Can't figure it out. What's going on?

In future you could use a Fumoto oil drain valve. I’ve got 2 on my Caterpillar engine, one on the Icepak sleeper A/C, one on my car and one on my Kawasaki bike. Had them for years, so convenient for oil changes and you’ll never have drama with threads again.

You need to drop the pan and replace an o-ring. The drain plug hole is modular, 4 bolts from inside holding it down. You need to remove it and replace the o-ring that seals it to the oil pan.
Im guessing it’s made that way incase someone strips the threads or cross threads, you don’t have to replace the whole pan. Will need a new oil pan gasket too.

Huh yeah that makes sense. Designing it to be able to replace the drain plug hole instead of the whole oil pan. That explains ring around the drain hole too, I was wondering about that. Damn I really dont wanna drop the oil pan... i might try to be a cheap bitch for the meantime and let the oil drain again over night and try to do a temporary seal with some permatex in that crack from the outside..

Unfortunately those temporary fixes wont do much at all due to temps and vibrations. That o-ring is cheap and quality oil pan gasket can be had for around $80 on ebay. Good luck

Oh and thanks for the responses and helping me out!

Kinda figured so. Those fixes never really hold up. I'll have to turn to my friend, YouTube on dropping the oil pan. Doesn't look too hard just from laying under it though

Bad gasket

either this or get a nice copper washer which will crunch down slightly and fill in whatever slight gap is allowing a drop. you can order pretty much anything on mcmaster

The one I got from the truck shop has the rubber on the inside of the washer. It's the same style that was on there when I first took the drain plug out. Wouldn't that do just as good to seal it off?
planetbuster@reddit
oh. yes it would, assuming its a rubber intended for that application. has to resist heat so it doesnt get hard and crappy, and that should seal it. so that means that flat surface (think of the outer couple edges of a dinner plate, all the way around) isnt mating together well. something bent/dented/etc? something breaking that profile so that those two flat surfaces arent flat or otherwise pressed together nicely?

Not that I could tell. It drained for a couple hours and I wiped it good and clean before putting the new washer on. I sprayed the bolt with brake cleaner and there was no debris on the washer.

Put automotive thread tape on the bolt before putting it in. It’s like pipe tape you put on hoses
