small oil leak sealant?
 

Long story short, I have some oil dripping ever so slightly from my oil-pan bolt, I believe the washer was not replaced and hence why.

I got some fresh oil in there and it would be a shame to flush the thing just because of this. The leak is very minor, so I would rather use something to just spray on it until my next oil change.

any suggestions?

If it's minor and not a big deal... why make it a big deal?

That said, you could clean the area, pop the drain bolt and catch the oil in a clean container for re-use. It's not like it spoils if you drain it.

For all my previous subaru products, I would always re-use the crush washer, but I would use a tad of some high temp RTV. Never had a leak. Ironically, I used new crush washer on the FR-S when I changed the oil and it appears that it didn't quite seal.

infomercial adevertisements, urgh

it's liquid rubber in a can:)

U can unscrew the bolt while the car is cold.. Hold ur finger over it.. Put on washer and screw on.. U won't lose much oil and can add a bit to bring it up to level.. I wouldn't attempt any sealants..

Flip your car, remove drain bolt, install crush washer, reinstall drain bolt, flip car back onto tires, profit!
