The T-shaped breather and grey valve looked crusty when I bought the car. Changed them out. no problems there. All the hose work looks fine. No collapsing / hissing.

i might bite the bullet and buy a ford coil pack. Seems silly wasting money on another shite one that'll only last 10k.

no fault codes stored. I need to get a live reader really and go for a drive. Mine is pretty basic and I hear some codes are immediately deleted on engine switch off on fords. Unless the eml light comes on.
