mate, it needed be, it doesnt always point to the rockers ... if it is then they cost on average about £85 each for the latest spec ones .... and I'd know ... I've had 7 in the last 12 months ... its not terminal and easily treatable, just not cheap as the heads have to come off ...

my advice would be call Neil at Cornerspeed and have a chat with him ...

good luck mate ...
