Lets play...guess the gasket!

4 is also for oil filter bolt. Don't forget this one or oil filter adopter will leak.

Are you sure???

I've never used a gasket for the oil filter adapter 'bolt'... There is no need to seal that bolt/thread - if it leaks, it leaks into the filter which is no problem... The gasket on the oil filter is what seals it from leaking if the adapter plate is installed correctly...

I would say that it is the drain plug gasket....
