I don't mind if it take me all day just wanna get it right! Most people take about 4 hours and ill aim for 5 haha! Just fitted my version D vavle! Not sure how much difference that will be! Since I've had ther engine cover off there's a high pitched noise that PISSES me off!! Only seems to happen when I put my foot down a bit! I have no idea what it is!!! How's your car??
