Hey guys, had my 08 fg xr6t getting the head replaced with a brand new one since the original was cracked and my mechanic noticed my cam shafts where worn in 3 different spots (exhaust side), inlet side was fine. The car has done 109000 kms, don't know the history of the car with regards to which oil was used, just bought the car 3-4 months ago, and coped this all in one go! fun times with my lemon
