    D3 Engine swap

    Can anyone advise what's involved (cost, time, options, workshop etc) in swapping a failed TDV6 from a 2005 Discovery? I'm lead to believe that it's a body off job and a Ford Territory is often used as a donor vehicle.

    Also, what are the most common reasons for TDV6 motor failure?

    The two common failures are

    1. The timing belt coming off due to the idler pulley housing at the top of the oil pump breaking off - kills the oil pump but the engine dies because the valves crash into pistons. (hence older oil pumps need to be upgraded to the later reinforced version).

    2. The crankshaft breaks - lots of views of what causes it but it seems one of the big end bearing shells move block oil to that journal where it seizes and the crankshaft breaks at that point.

    Later 2.7s - like fitted in early D4s and the Territory seem less prone to breaking cranks and do not have the oil pump issue as they have the later pump.

    Or the timing belt itself failed if not changed on a 2005. It would be past it’s second change date now in any case just in years. How many kms?

    Or the plastic coolant junction on top of engine split and you cooked the motor. It gets changed at 7 years with timing belt.

    Or someone reinstalled the oil filter without properly locating the nipple.

    Lots of unnecessary no fault of the motor ways to kill any engine as they age without good R&M.

    Not sure how many kms yet, but I believe under 200,000.

    I've had a read of A Comprehensive Guide which is really interesting. However, given this is about EU4 and onwards, I'm still a bit confused about options for a EU3 motor transplant.

    7 years *or* 160,000km for the belt.

    There is a comprehensive Territory engine swap guide here on Aulro somewhere.

    The EU3 engine needs the high pressure fuel pump and injectors swapped over, plus everything else that normally applies to the EU4 motor

    So, simply put in the EU4 Territory motor and use the fuel pump and injectors from the original D3 EU3 motor? On the flip-side, How much extra work is involved in swapping over to a complete EU4 motor?

    Any idea on cost to repair either of those scenarios? And is it worthwhile, or better just to do an engine swap?

    I havent heard of anyone converting from a EU3 to EU4 engine completely. I would say at the very least it would involve and ECU swap, but there would probably be more to it than that

    There is more to it than that - basically strip the two engines down to long engines and swap all ancillaries over from your old engine to the new. Sumps included.

    In a convoluted way it is all covered in the thread about putting in a Territory engine into a Disco.
