Well today my mechanic got back from the WRC Jordan event, and he got round to checking my car. So turns out ( so far and fingers crossed ) nothing is wrong with my engine's head gasket, but turns out my radiator is completely clogged up and it had to come off and sent to a specialist. We also checked the spark plugs of each cylinder and all seem fine but running slightly lean. anyways tomorrow i get to take the car home and we can start proper fuel tuning and set up.
will keep u posted guys, and thanks for all the help and advise.
