Which side of cam oil line connecting screw (#48), goes into the engine case?

[H.G.P.]

Engine case diagram (early 911 Pelican diagram), #48 screw connector, cam oil lines to case:

Which side of the screw connects into the case. The left part (in the pic below) which has the "lip"(that looks like a washer but is actually a part of the screw connector), or the right which doesn't have the "lip"?


Thanks

That's as clear as the old (cheap) digital can give at close up. But the "lip" that looks like a washer, is still quite visible in the photo.

The "lip" (washer looking part), is just to the left of the "nut" looking part of the screw. The entire thing is one solid unit.


Thanks

It only goes on one way ... the case threads are M12 x 1.00, and has a 'flat' surface that the sealing ring seats on ... the other end takes the compression nut and ferrule from the hose end.

Just a hint for the next time - take the pic from further away and then expand it in your imaging software. Grainy is easier to see than blurry.

OK, thanks Warren. I was looking at this from just the case standpoint, after bringing in one of the cam lines I see now clearly.

Thank you.
