3. You absolutely sure it's the tappets? Check that it's not the exhaust manifold gasket blowing, as that can make a similar noise!!
i didn't know you could change the cam with the head still on i didn't think it would be enough room. i would just pull the head of but last time i took the head off i snapped 3 or 4 head bolts so i feel a bit dodgy about doing it with this engine. its not the exhaust manifold there is a new gasket on it and it was like it in the rs i took it out of.
thanks for the advise much appreciated
