I have decided to try to remedy the fumes coming into the car, seem to be worse when fan is turned on.I wish to dismantle the manifold and downpipe, I can hear a slight blow when the engine is cold. Question is, how do I go about this, from the underneath or from above?
underneath is better,take the wheel off for more workin room,
if the bolts r tight u mite hav to heat them up so u dont snap them
