Misfire on cylinder 5

Agreed, changing the coil packs in place was not easy. That said, if you don't have secondary air and have small hands, unclip the wiring loom from the bulkhead, remove the right-hand (passenger-side) spark plug wire bracket and it's quite feasible (you just have to turn the coil pack in place to unscrew each coil from the bracket, then pass them out the right-hand side [[your left]]).

Thanks for the PCV tip. This Disco is replacing a Volvo 850 which are also notorious for PCV clogs, so I'm all too familiar. I think AB's valve cover seal video shows replacing the oil separator for that very reason. Any other PCV components to pay special attention to?

All the hose connections, seems that Rover isn't to fussed about using hose clamps on these connections and they start to fit loosely and leak inward and outward as they please.
