Not so fast nhdoc, these 606 are anomolous motors, this one being a " mid year" with oversize exhaust valves. MBZ was of NO HELP in finding the right part, so I authorized the shop to use a good 7mm teflon seal of the right config and height.

Plus, I aint pullign the head again. Its a royal PITA. If the exhaust seals arent shreddeed up, I cant see why they'd fail.

Pulling the oil past the rings, huh? New one on me, but I've come to realize the deisel is bass ackwards from gassers. I could see blowby increasing, but.... I DID NOT freshen the lower end as the cross hatch was intact and all looked well.
