Disco 4 (LR4) engine rebuild? or bin.

steviebacon · Jul 13, 2020

Hiya all.
So drove into work this morning all good.
finished @ 9 started travelling back , sounded like something was catching pulled up to a mechanics , he listened said he had never heard anything like it.
managed to get home all good.
started the car to drive back to work this afternoon.
got 3 miles out of the 5 and the car died.
will not start.

no smoke, no smells, when you are trying to start the car the "catching " sound is still there.

mechanic reckons new engine/rebuild but unsure as to what it is.

Question is:
is it worth investigating, or just bin cutting my losses..
car has been serviced on time, and properly last service less than 2 months ago.

If the mech buys it, it will be so he can sell it on a sit, or replace engine then sell on, the 3.0 does not have a good rep in the trade, tbh no land rover has a good rep in the motor trade!

yeah he has the space to strip it down.
It is the fully loaded version so there is a lot on there that can be stripped and sold individually. he also has teh time to repair at his own pace. which I think he would do then use it on his woodland for training/wrecking.

shame was alovely car to drive

Just get a second hand engine and replace the duff one.

I just love it when a mechanic says.......i dont know what it is but it needs a new engine.
That's how I got my L322 previous owners mechanic said it needed a new engine so I got it cheap. Fixed the minor issue and been driving it as my daily ever since

If you got space then sit it in the corner and get a punt motor to get by while you save and search for accident damaged motors with cheap engines to pull out, that's how we always did it.

+1 on that
Given time, you should track down a replacement engine, get it sorted and get back to enjoying it again.

Have you indeed confirmed that its the crank that's snapped?

steviebacon · Jul 15, 2020

not yet. but going off the videos it looks highly likely ..
so far engine prices are coming back 4k +

which means its going to be scrapped/sold for parts currently

Search for "PSA Lion 3 litre diesel" it was used in other vehicles not just LRs I know a guy who got a new 2.7 V6 diesel out of a Peugeot that had been rear ended.

You're scrapping a £12k+ vehicle for a £4k engine?

Those maths don't add up.

£4k for an engine might not be feasible at this moment in time?

Scrap it in my direction ffs il fix it.

Plus labour, plus cambelts/tensioners/oil and filters and anything else that goes wrong, and boom there you are at 6k minimum, then there is no gaurantee the 2nd hand lump is any good

I think youur mate is going to be dissapointed, as I understand it yes it is the same 2.7 but the pug block has so many differnces it will not fit, jag ones are okay though.

True, if the spannering can't be done DIY.
It still seems a strange move to scrap such an expensive vehicle, when the repair isn't even half the value.

The OP could actually sell it as is, and still get a sizable amount for it, far more than scrap value.

I'm sure the crankshaft is now available, although that's no use if the block is damaged.

I've done an engine change on a D3, which used a second hand engine from a Jag S Type. The owner of the D3 bought the whole written off S Type for about £1800, we then stripped it and he sold off pretty much everything of value, and we used the engine in the D3. He actually made most of the repair costs back, simply from selling the Jag bits off. I'm sure his engine swap only cost him about £500 in the end, and that included the new belts, oil pump and other bits needed to complete the job.

I will say that a D3 engine change isn't for the faint hearted, but it is doable at home, with nothing but a decent engine hoist.
