    Question Purchase a D4 with replaced engine

    Hi folks,

    So once upon a time, i sold a discovery, I learnt a head lesson - LC200s are horrible. Not only was it terrible to drive (day to day), it was expensive on fuel, used oil, lacked many creature comforts that made it a nice place to be, and generally proved to be no cheaper to service than a D4.

    Fastforward a year, and I am hanging out to get back into a Discovery (4). Looking at 2014-2016 models only, and have a few extras I am looking to be on the car. I have found one, but it has recently had the engine replaced (crankshaft failure victim). And I wonder if any one has any experience of owning one after the engine has ben replaced?

    This car had a reconditioned engine put in, and I understand that they use a Gen2 Crankshaft amongst a lot of other new parts. so the theory is that you have a "better than new" engine. But I wonder what (if any) other issues are caused by doing open heart surgery as it is. Has any one experienced it? Have any advice?

    Many many thanks in advance

    I suppose it depends if you have confidence in a vehicle that has been pulled apart,and a rebuilt engine.

    For me I would move on and look for one that has not had those types of issues.

    Good luck with your search.

    I agree, i would prefer an original unmolested vehicle but i also see the temptation in a new motor IF it was a new crate motor and not a rebuild.

    It would be worth finding out who did the heart transplant. Then go and visit their workshop and talk to them. If it was an LR dealer I would think it would be covered under their warranty. If an Independent specialist then again assess them and talk to them about their warranty.
    There is no reason for there to be any other problems if the job is done correctly.

    If you can find out who did the engine rebuild and have a talk with them. If you are satisfied the job was done best practice, then I'd have no hesitation in purchasing it. If you go ahead and buy, just remember to change oil/filter every 8-10,000klms and use correct oil spec. I'm using Penrite HPR5 which is 5W40.

    Thanks folks, It's interesting hey. Part of my likes the idea of the engine being "better than new"? The crew that did the job was Hank at Automotive Skills (www.automotiveskills.net.au)
    They do a full rebuild (not a crated engine) and apparently use a crankshaft that was redesigned in about 2018. Luckily they are very close to where i live, so i will 100% be popping up there tomorrow to have a chat. Online reviews are 10/10 FWIW.

    This was his email to the original owner - im sure there was a lot more detail and many other emails exchanged, but this is the crux of it

    This service includes a Reconditioned long bare engine. To give you an idea of the work that goes into these engines are as follows:
    • Engine is stripped down and the block, crank and cylinder heads are processed through our reconditioning machine shop.
    • Cylinder heads are reconditioned.
    • A reconditioned OEM crankshaft is used.
    • Block is inspected and honed or bored as required.
    • Engine is then re-assembled using new parts, such as crankshaft thrust/main bearings, big end bearings, pistons & piston rings, oil pump, new gasket set including sump gaskets, rear main seal, oil seals etc.
    • Brand new water pump is fitted.
    • Brand new timing chain, chain tension & guide both Left & Right is fitted.
    • Brand new timing belt kit is fitted.
    • Brand new cylinder head water connector is fitted
    • (I have also attached some images for you to see)
    • To this engine we fit a pair of overhauled turbochargers. This is on a service exchange. So we will keep your old turbos.
    • Tested passed diesel injectors. This is on a service exchange. So we will keep your old injectors.
    • There was a Land Rover rectification in regards to the turbo return pipe. If this has not been already done then it will be part of the service.
    • This service comes with a 12 months parts & Labour warranty.
    • Please note: Sold on a change over basis this means we will keep your old engine.
    • Please note: Anything that is not mentioned in this quote will be the vehicles original components. We can not guarantee the life of your original components.
    • Some info for you:
    • In the past we dealt with 2nd hand engines however stopped due to the poor quality and warranty that is offered.
    • This is why we have created this special service.
    • We have completed engine jobs for vehicles that have travelled as little as 40,000 Kms to 150,000 Kms
    • You will find most 2nd hand engines have travelled well over 100,000 kms.
    • A vehicle will travel at average 20,000kms per year so if it the engine is out of a vehicle that is 5 years old chances are it has done 100,000kms
    • Overall 2nd hand can be very risky and might result being in the same situation in the near future.
    • If you have any further questions please feel free to give me a call.
    • We have a very reliable well priced transport car carrier network so if transport is required please advise for a very reasonable quote.
    • Alternatively we do purchase these vehicles with failed engines. Please give me a call for a valuation.

    I mainly hear about them giving up the ghost from anything between 50k-130k. But after that it seems stories are less? I dont really want to get caught up with trying to guess, and to be honest, i know owning a Disco is as much about the heart, as it is the head. But yeah, i do wonder as there are a lot of nice models available with 130-150kms

    I’m confused. It went from a redesigned crankshaft to a reconditioned OEM crankshaft. I can’t believe a redesigned crankshaft needs to be reconditioned. It should still be happily circling around in a happy engine.

    I'd like some evidence that the later crank is better.

    In the UK many claim that the "landmark" 3.0 D4 had a revised crank.

    If it does, and it's better, and the one you are looking at also has that, I'd go rebuilt for sure, it should be better than factory if they know what they are doing... and care.


    Edit: I missed the reconditioned crank vs new bit, that's not right..

    Sorry lads, mushing a few conversations with the owner together with the email. I will clarify tomorrow 100% and comer back to everyone
    He made a point of telling me that its a "V2" crankshaft (whatever that means) and it was basically LR silently admitting that the old design was faulty. It's pretty much the first question I have for them, and i will go from there.

    He mentioned that they hone a lot of things out as part of the reconditioning process, using a stone, but to be honest its all pretty over my head mechanically.

    I hear that there are a few other parts that were improved upon after the D4 was discontinued, can you think of any other questions for him besides what was in his email?

    i.e I assume they check the block with a fine tooth comb, but not knowing how back the engine heated up (lets imagine they didnt kill it immediately and cooked the engine also) woudl there be anything else further from the engine that might also suffer damage?
