on a 90 300CE DOHC, 160K mi. took it to an indy shop and local Benz dealer. Both say it's just external head gasket leak w/ no oil into cooling system. Both quoted $1300+. Think I might just tackle this damn thing myself. Figured if I can pull/drop rotary engines, a dinky Benz head gasket shouldn't be that hard.

So the question is: Valve job, everyone seems to say yes (in the archives at least). How much should I pay? I don't want 3-angle or anything, just a 'refreshment'.

Water pump, it's right there, should I do it? Timing chain, also right there, do it as well? TIA!
