I'm about to bite the bullet and replace the head gasket on my E320. What I want to know is this; exactly what gaskets will I need to have ready to do the job. I know I need the timing cover gasket(s) head gasket (obviously) and the green U-shaped one but what else do I need (and do you know the part numbers?). The method recommended by MB has you leave the exhaust and inlet manifolds attached to the head when you remove it so the gaskets associated with those won't be needed (but are included in the kit from MB). I don't want to buy the whole gasket set just to throw most of the parts in a drawer if all I will use from it is the head-gasket.
