I've got a 1988 300TE 12 valve auto (UK model) and whenever the revs go over
4,000 (yes, I know - I drive it on Sport mode everywhere) I get a puff of smoke.
Also, oil's being used up and there's a creamy deposit in the coolant reservoir.
Could the head gasket be gone? If so, is it serious? What sort of cost is involved?
Thanks
David
