    I found a company by the name of LDR Engines. Bad rep on Hello Peter, good rep on Google reviews. Their engines are sourced in the UK and (supposedly) all have less than 100K on. Took the plunge and bought one.

    Complete (15P) motor with Aircon, Alternator, Power steering Pump, Fan, Starter, Flywheel, clutch-plate, pressure-plate, the WORKS, literally plug and play. Cost me R29K with a 3 month guarantee (installed it myself. If they install it at a cost of 5.5K you get a 1 year guarantee).

    Have done just under 10 000 k's with it now and am VERY happy!
    That sounds like a seriously good value, isn't R29k pretty much the price you'd pay for just a new head and fitment?

    Plus you can still sell your old engine for parts with the extra ancillaries and recoup a good few thousand Rand.

    Agreed.. this was before I owned her so I will be watching this repair closely

    Correct. A new ("naked") head would have been about R20K. Add valves, springs, valve stem seals, cotter pins, seating and grinding of valves, etc - plus you only get 12P and up - the 10P had its fuel return running inside the head (That was one of its weak points and also why they were prone to cracking) and 12P's return runs outside, so it would have entailed some modification as well.
    ENJOY!!!

    I bought an AMC 10P head when I did my replacement, and, I had the choice of with or without valves, too. Granted, it is a few years, now.

    Feedback from engineers: Head has no cracks and holding pressure. Exhaust valves on their way out so replacing those and adding a bit more engineering.

    Was wondering if there was anything else worth doing while the head is off?

    Did they check if the fuel rail is holding pressure or just the water jacket?

    good question, considering a lot of heads fail between the fuel rail channels and the valve galleries I think

    If you did not send injectors with they did not test the fuel rail, unless they have their own set of injectors to test with..

    If they don't have the injectors then I'd like to know how the tested the fuel rail..

    Are you sure you're not being given a BS story?

    The repair is being done at a well known Indy and the head removed from the vehicle and stripped and sent away by them. Appreciate the heads up but I have received great service thus far.

    I presume they would have sent the injectors with but will ask to make sure

    The Disco now has a surging problem that they can seem to troubleshoot.

    Need some advice dealing with the mental anguish of almost but not quite there.

    Fuel regulator was leaking and replaced. Not sure if that was the cause of the surging but she is a different vehicle. Smooth as silk! Happy days. Time to put on some miles. Thanks for all the input.

    Now to test some of Markus' venues in KZN and beyond...
