My '09 has leaked off and on from the same since I bought it with 6K miles on it a few years back.

Sealed it, and it stopped leaking.

Now leaking again - and I had changed the oil not long before the leak started.

I put a quart of Polydyne TX7 in it in place of a quart of Rotell-T Synthetic (blue jug, 5W-40).

I'm thinking that may have something to do with it. Once I get to that next oil change I'll change it w/out the Polydyne and see what happens. Just a suspicion - the additive may be having an affect on the seal.
