Hello-

Just completed installing new oil cooler lines on my 300sd. I'm getting a leak at lower fitting on the oil filter cannister. Tell me if I'm doing it right:

1. Tightened the 24mm male/male union clockwise against the cannister.
2. Tightened the 1 1/16" (27mm) oil cooler line nut clockwise against the male/male union.

The oil leak seems to be coming from the connection between the male/male union and the cannister. I've tightened the nut hard against the cannister, can't seem to get it any tighter.

Am I missing a part or something? Is there supposed to be a crush washer between the union and the cannister?

Wiggling the oil cooler lines out is supposed to be the hard part of the replacement work...that was easy compared to this...what a PITA.

Thanks-
Rob
