    Head Bolts for XH 4.0 sohc

    Do NOT use second hand head bolts in a 4.0L They are Torque to Yield, when you tighten them they are literally tightened until they are at stretching point. Rule of thumb is any head bolt that is tightened to a degree setting instead of nM/ft lb should be replaced. Most gasket manufacturers recommend new head bolts when replacing a head gasket regardless as well.
  2. The metal pipes are not easily obtained from auto parts stores. Normally they end up being genuine or online. The header tanks/coolant bottle are pretty regular on the shelf items.

    Which 4.0 into Ratty XF Ute?

    Far from it. Xflow top hose goes to driver's side, lower hose to passenger. 4.0 OHC are opposite way around. Plus there's the extra hose on an XG radiator for the expansion tank inlet

    why rebuild a crossflow?

    Originality of the car, simplicity, personal preference, ease of parts, are a few that spring to mind. I love my Barra swapped LandCruiser but I'd never put one in my XF wagon.

    I do recall a customer not long ago with a Barra turbo XE and they used a VL or similar radiator now that it's mentioned.

    Soluble Oil instead of Coolant.

    I've been asked for soluble oil before and had no luck finding a supplier. But most Repcos keep this on the shelf. I personally run Penrite corrosion inhibitor in my XFs with no issues.

    Well there you go, good to know. Weird how they changed things from model to model. Change the hell out of how the radiator sits on the bottom, but use the same crank bearings for 50 years

    I think EF/EL fans on a XG radiator is the way to go? Or just aftermarket fans. Xflow radiator will have the hose inlet/outlet on the wrong sides. XG radiators are rare I believe but might bolt straight into XF (I'm pretty sure) and have the hoses in the right spots, and the outlet for the overflow bottle.

    Do you have power steering and/or AC?

    Definitely, get the pedal and the plug with as much wiring as you can

    Pretty much all the engine wiring except the alternator and starter connects to the ECU with two big plugs. Once undone all the wiring comes with the engine. The ECU is riveted to the shock tower and is a giant pain to drill out. Then you'll want to cut the wires from the ECU as far back near the firewall as possible.

    They annoyingly changed oil filters for BF onwards, Z516 instead of Z9. Guess they thought they should finally use a metric threaded filter.

    Just ran in. BF is probably the pick of them for swapping into an earlier Falcon. FG onwards get a bit complicated with the rear sump & dipstick etc. I'd pull the sump and timing cover, clean them and reseal them. They basically leap from new around there, so 250,000kms wouldn't help that. Gives you a good chance to see the inside of the engine too. Good time to paint the rusty block too [emoji23] If you've got a spare rear main seal from a late xflow it'll fit the Barra. Same goes for the crank bearings.

    Oh absolutely. The Barra transformed my Cruiser, and that still weighs 2.5t. But the other big advantage to the Barra, is you can tune the stock ECU. Pretty sure to do pretty much anything to EEC-IV or V, you need to chip them at minimum.
