Message Anyone ever had this issue? This guys Z has leaking valve seals fyi. I cleaned the rear of the head so there's not a single oil spot on the pass and most of the driver head/block. I just did valve covers + vtc + moon seals. For a second I was thinking the VTC was leaking, but I epoxy'd the pass side up and they're good. The pass exhaust is burning the oil into smoke. I also noticed a layer/puddle of oil onto of the transmission where it's flat and has a 1/2" trail of oil going diagonally down the transmission. After cleaning it all I drove and notice the puddle came back and the bottom of the egr valve is oily. I'm guessing the valve seals are leaking under hard decel of 5k+ rpm and the egr valve is activated, but is leaking...

The pass head is oil-less now so I want to say any of that is eliminated.
