Title: Oil drain plug question
Post by: blown motor on June 15, 2020, 01:26:04 PM
I dropped the oil in the Charger and this is the drain plug. I assume the white material is to form a seal. What is it? Is there a better solution?

It looks like somebody bit onto it with a vice grips at some point.

It's just a nylon washer.(drain plug gasket)  You can get a replacement at your local parts store.

That's about what I figured but that one looks rather mashed.

Or replace it with a fumoto valve. I have them on my Cummins and BRZ. Not on the Challenger yet though.
Makes oil changes very clean and easy

I have Fumoto's on every car now.
Makes it so much easier, no mess, no hot oil burning your hand as you try to quickly pull it away, and best of all, no chance of cross threading or stripping out.

Cool idea but as this video mentions, with this valve in place it allows about 1/2" of oil in the bottom of the pan. That's where all the really nasty stuff will go and you would want to remove the most?

I didn't watch video, but not true, the valve is below the opening in the oil pan, so how can oil be left above that?

Yes, valve is below the pan. Issue I see is the threaded bung. When pulling plug there is no rise. Just an open hole.
The way I see it is the bung threads are long and protrude into the pan. This protrusion is what will contain the oil and crud below it.
As anything above pan threads are irrelevant. Machining the bung threads shorter will alleviate this issue.

I always jack the car up so the oil pan is never level, and drains to the lowest spot.
The couple of tablespoons that may be left in the pan are worth it to me.
I'll never have a car without it.
