Can anyone shed light on why preference seems to be to fit an exchange engine be that 2nd hand, refurbed or crate TDV6 rather than rebuild like we used to? Is it the cost of all parts plus the time is more than the cost of a crate engine? Or do they require some particular expertise to rebuild other than the usual checks you would perform when rebuilding a modern engine?
I ask as I may need to be doing one of the above depending on what I find is causing the knock on my D3. 2009my Discovery 3 2.7V6 HSE

Most of the time, the wear or damage dictates if it is to be rebuilt or not on these engines.
The “most frequent” major damage on these 2.7 engine’s is a spun mainbearing…
I have seen 3 tdv6 engines, with a spun mainbearing.. in all 3 cases there was damage on the crankcase due to the spun bearing(s) Line boring crankcase’s is not for everyone….. oversize/undersize bearings not always easy to become..
Camshafts run directly in the alloy, not in bronze bushes like in the “old days”
Etc. Etc..
Oval auto’s use to rebuildt 2.7l engines though, but what i understand there is not enough money to be made to continue that type/model engine nowadays…
Maybe they will kick in here… Best regards

In the event I do require a replacement engine, can anyone direct me to a recommended supplier of all parts to rebuild one (I realise this could be JLR only) and also a recommended engine supplier for a full crate engine?
I can only find Craddocks that supply a crate motor but for a D4. How easy would it be to fit a D4 engine into a D3?

I used both advanced factors AND island4x4 for parts as some parts differ hugely in price if compared
If you use ALL the D3 ancillaries from the D3, incl the HPFP etc. On the D4 bare ! engine will run fine in your D3.. Best regards

There are many untrusted rebuilders out there. I think this is the issue.
Part supply was an issue.
Also the genuine crate engine has 2 year warranty.

Many thanks Harold, appreciate the information. I may well go down that route, do you or anyone know if this has been done and what was required? D3 turbo i presume.
Pete K, thanks also, that was the reason I asked, are there any forum recommendations for engine suppliers?
Thanks

We used to do like Oval Autos (forum sponsor, with sub forum), but they have given up doing the 2.7 as it's just too expensive, in comparison to the value of a D3.
Actually they don't appear to be a sponsor anymore. Sub forum has gone ? 
I think someone reported they were happy with one of the other builders, but can't remember who.
You could give us all a laugh and try contacting these people and see where it goes:

At least you can see what you are getting.

proper reading seem to be difficult these days....  (as i see this a lot..)

ALL ancillaries is mentioned as is bare engine and that means Every ancillary of the D3 ....
and you can just use the BARE but complete engine block = crankckase, heads etc incl internals..
EVERYTHING else needs to be transplanted Best regards

Whilst I appreciate the lesson Harold, a turbocharger is not an independent device unlike other ancillary components on a vehicle, such as a power steering pump for example. It is an intrinsic part of the vehicle's power system. 2009my Discovery 3 2.7V6 HSE

That is why i added the word BARE engine
since english is not my native language, maybe the term "bare" is not clear enough?
short block + heads does that sound better? Best regards

Could anyone recommend an engine specialist experienced in the 2.7 TDV6, possibly north west England, but not averse to travelling anywhere for the right establishment. Maybe had their engine rebuilt successfully.

You have probably found your rebuilder by now. In October 2022 I had my MY16 D4 SCV6 engine rebuilt by NZ Engines of Rainham, Essex.
The old engine suffered a catastrophic loss of oil pressure, blowing the big end and splitting a camshaft at 190,000 km, stranding the car at the top of the M6 Toll motorway. We recovered it to Lancashire. A friend of a friend in the motor trade in the Northwest recommended NZ.
NZ arranged for the car to be lifted down to Rainham. They stripped and inspected the failed engine and fitted a factory new short block, new camshaft, and new injector. It was a body-off, engine out job. The workshop boss shared progress photos on WhatApp. The rebuild took about a week. In the 6 months since, we've put another 15,000 km on the new engine. It runs very well. The price was reasonable, and was competitive with other offers I had.
NZ's yard is full of LR vehicles - D3/4 and RRS. They were also working on a recent model Porsche 911 and a Mercedes when I visited, and they do light commercial diesel work. They were very busy, and I have no doubt their mechanics could do a LR TDV6 in their sleep. I recommend them.
I will be changing oil and filter every 6 months / 12,000 km from now on. The manufacturer intervals are there to please the fleet buyers. Never mind the synthetic-oil-lasts-longer nonsense. There was quite a lot of varnish in the cylinder heads, and oil is far cheaper than a new engine.
(Now back to my hibernation.) MY91 110 CSW, so long ago I can barely remember it - sold
MY07 D3 TDV6 HSE with all the extras - sold
MY10 RRS TDV8 Dynamic - sold
MY16 D4 SCV6 HSE
MY16 RRS SDV8 Dynamic

Many thanks for the recommendation Stuff, as yet the old girl is still going, injector knock has been suggested.
Ian Bodsworth with his able bodied colleague Clive Symons, great men that they are, recently changed all transmission oils in our families 3 disco's and didn't report an issue with mine. So, I am going to sort the injectors as I am now developing a misfire on start up, runs fine after a few seconds. 2009my Discovery 3 2.7V6 HSE
