Looks like I'm going to need a Ford bit too, but mine looks different to the others I've seen on here - no diaphram - is there a different part number for obd1 engines? Also does anyone know the name/part number of the plastic box (4 x 3 x 1 inch ish) at the very top of the breather pipes as mine is cracked, (not shown in pic), and could its failure result in oil dripping onto the exhaust manifold? (Yes that is fuel pipe being used instead of breather as I had some left over from replacing the fuel pipes8-))
