    That’s good so any trapped air must come out of the breather hole at back of pump?
    The bungs fit the holes where oil cooler pipes would be you can see one of them on the filter housing in pic above
    I’m tempted to get it going on a pallet as a test

    Trapped air will go to atmosphere via the injectors, spill pipes.
    Do not run the engine with the ports blocked on the oil filter, iirc that will stop oil flow round the engine and you'll have to rebuild it again. Not 100% on that but pretty sure.

    No breather hole on the FIP.
    You're seeing the rubber vent just below the 'flying saucer' ?
    No fuel gets in there.

    It's to allow air in/out as the rubber diaphragm moves up/down.
    That pipe from the turbo running round the front of the head controls it.

    There is a pipe ive not really looked at, dare I say it mine will be a 200di , just looked at turbo the other night and there seems to be a lot of play in the fan
    So without a turbo fitted what should I do with that pipe

    Disconnect at the pump end and replace the banjo bolt with some more washers incase the bolt is too long?

    Don't throw the pipe though incase you decide to turbo it again.
    Some person might need it on here because theirs is holed, it happens.
    I think I read somewhere that they are a stupid price new?

    The 200 in my s2 has the ports blanked and they have been like it for years, I took the original unions out, stuck a cut off bolt in the hole and welded them up and stuck them back in, dont think I removed the oil stat? not saying its right but oil light goes out sharpish and shes had some hard over the last 7/8 years, getting tired now and breathing a bit, but she wasnt that healthy when I fitted the lump.

    Let us know port orientation.
    Oil stat may not work in hot water as water might not get hot enough?
