Guys..For the past week i have been smelling petrol in the car when i first start it then its fine - i have changed oil to shell helix and put boch super plugs in to try and help - people have told me she overfueling - a week ago i reversed and cus my back box is massive i hit a kerb - i think that its broke something at the front end - now when i first start her she sound like a tractor and the noise is coming from the back of the engine - where the manofold is - when she warms up its no as bad - obvisley when metal heats up its expands - what u think guys.
