S54 large sump plug, no not the oil drain plug.

I have a very slight oil leak at this plug on the sump.

Is the torque value for the plug known?

Has anyone else found oil leaked from here?

Never heard of a leak from there, but looks easy enough to put some thread sealant (such as Gasoila) and retorque it the next time you do an oil change.

Torque specs are hard for those kinds of threads. Take note of how many threads are showing. Don't overtorque or you risk cracking the pan.

Thanks, it doesn't appear as a part on RealOEM.

It must be at least a 20mm Allen key.

It’s a 22mm allen. I take them out on my rebuilds, from factory they have some kind of green thread sealant on the threads and they can be very stuck.

I mark both the big plug and the oil pan with a center punch, and then count the amount of rotations until it falls out, then when it is time to put it back together I apply new thread sealant and tighten until my punch marks line up again.

Top stuff. Thanks very much.

I wonder if it is for dry sumping purposes.
