The little plug next to the oil filter.....what's it called & how do I change it?

[SoCal Life]

Yeah, what the title says?

Mine is driping so I need to change it. I'm sure if someone just tells me what it's called I can search for a write up on it and do it.

Any help.......???

The only plug near the oil filter that I remember on an M20B25 would be the coolant block drain plug. It is sealed via a crush washer. Replacing the washer, or the plug, is simple and obvious.

But you might be referring to the oil pressure switch that is also near the oil filter.

I was thinking the same thing.

Oil thermostat plug? Held in with a cir-clip?

You get the kit from BMW (o-ring, clip and plate) remove the old one and replace it all.

It is spring loaded in there so it takes 2 1/2 hands to put it in and snap the new clip.

Yeah, that's the one. I have cir-clip pliers so it should be a snap. Thanks guys!
