    How did you drill and tap the clutch release arm pivot pin? I tried to centre punch a spare I've got, but it looks like it's hardened steel.
    The Formshield is holding up quite well except directly above the turbo, same as Ben. The foil has detached, so I cut the loose foil away and patched it with some metallic insulation tape......ok so far.

    I can't remember having any trouble drilling and tapping the pivot pin.

    Cheers, Murray

    Okay, thanks for that. Formshield really seems like the best you can get - can get easily, anyway. The specs show next to no flammability but I also try to set fire to these sorts of things just with a match and it was quite hard to burn. So once I've replaced the open-crankcase 2.25 petrol I've got, which sprays oil mist everywhere, I'll put Formshield in the engine bay.

    The pivot I've got might just need some hardness ground off, so thanks for letting me know about that too.
    At any given point in time, somewhere in the world someone is working on a Land-Rover.

    The Formshield also comes in self adhesive, so you just cut it to size, peel the backing off and stick it on.

    The turbo breather from the tappet cover vents to a catch can type arrangement and then to atmosphere (no idea how it drains). I have temporarily been running mine with no catch can - until I refit my Provent - and the top of the front diff is a bit oily as a result.

    The catch can is vented to atmosphere and has an oil drain to the sump - see pic below.

    Edit: Murray's pics of the 4BD1T breather doesn't show the catch can. It mounts on the bracket just in front of the Land Rover air filter, where the hose clip is in the pic.

    Cheers, that helped. Provent sounds like a good idea to

    In the top right of the previous pic, is the plate I made that bolts to the engine block in place of the oil filter housing. The plate is drilled and tapped for 2 fittings - one for oil delivery that goes to remote mounted full flow and bypass filters, the other for oil to return from the bypass filter and a Provent breather.
