    300 tdi freshen up for cross country nullabor trip

    Plan for the disco is to freshen up motor.
    As with all my landies i like to replace mains and big ends as motor is at 300k. Im thinking replaceing the cylinder head as well for a complete turner kit as when doing a recent head gasket change (may of been a negative diagnosis) i had the cylinder head cleaned up and resulted there was a crack next to a valve. Shop after cleaning up cylinder head knowing there was a crack skimmed the head.. ! I would of scrapped the head but cylinder held pressure. I dindnt get a chance to pressure test it to 130 psi as i normally do on questionable heads. Anyways i reinstalled the head as it was going to be a local tracks 4x4.
    Now plans are to go across nullabor.! Lol hence the new head idea.
    Hence plans are to remove motor and freshen up with
    new big ends
    mains
    Core plugs
    New fan hub bearing
    Rear main oil seal, im worried about doing those t seals. Any alternatives? LOCKTITE?

    Because the block would be free from vehicle i would of thougt it would make sence checking bores and replaceing rings? Is it worth checking bores with micrometer?
    How do you check function of oil squirters? Is it possible to upgrade oil squirters to keep pistons cooler?

    T seals

    I use locktite 5910 for the t seals and sump.
    The hs 2.8 manual says to use silicone, so 5910 should be ok.

    Rear main seal, get the hs2.8 from turners and use a gasket not silicone.

    Dont forget the one behind the waterpump housing and do the p gasket.

    If your going that far it might be worth doing the quicky reseal on the ip getting the input seal and head seal

    Where abouts are you located ?


    The oil squirters have a small check valve, easy enough to check operation


    Boring and decking the block might be worth considering, new pistons and rings are not that expensive.

    Re freshen up

    Located south east melbourne.
    Ive done the core plug behind water pump so all good. Will be doing rest of them especially the rear one!
    I didnt think of the injector pump so ill get the front seal and tip seal and bush replaced by ag diesel on westal rd.
    Ill prob install v8 radiator 3 core radiator seeing going across nullabor with air con on 40 degrees towing a trailer seems abit serious.
    Im thinking also to get rid of the engine oil cooler from the radiator and having its own oil cooler. Or should i t the oil extra oil cooler?.
    Also ill be upgrading the zfhp22 oil cooler to something bigger and doing the saudi grill mod if i only can find some mesh. Any ideas?

    If you're towing .. for sure do the trans oil cooler.

    What type of mesh are you after?
    Dunno any mesh sellers down your way, but there's a mesh selling specialist out Truganinna way.

    What time of year are you going across? .. soon? .. mid year?
