Geting ready to R&R the head gasket on my 1993 300E 3.2 (oil in coolent) I have already bought Elring headgasket set, Hepo waterpump, belt tensioner and adj bolt. I have read all information on the forms and will be pulling with exhaust and intake attached. Should I replace the 14 head bolts. And does anyone have a PDF/link to cam timing? Waitng on tech manual to cover head bolt torque. Cover me I'm going in.
