I now have 3 x tdv8 engines here that are all knackered in various ways.

1 x previously rebuilt by one of the E bay specialists any engines that failed after 1,500 miles with low oil pressure, having previously been rebuilt at a cost of £5K, Trading standards are involved in that..

1 x bought a running engine, but on removing the sump had a piece of piston skirt lying in the sump, not stripped.

1 x second hand unit that was taken from a stolen recovered car which has water damage on one bore.

I also have my old 3.6 TCV8 that needs any engine.

Challenge is who to actually rebuild an engine.

Landover use a 3rd party company who build exclusively for JLR based in Grantham, interestingly I know of 2 range rovers that are in the process of getting 2nd replacement engines fitted in the dealer next work under warranty after the first JLR supplied recon engine’s failed, both jobs are obviously warranty.

Its can’t be that hard surely? We can build old classic engines and get all the parts so why are 3.6 tdv8’s so apparently impossible to get properly rebuilt. Hartec do the Porches engine, and re-engineered out the failures, the like of Turners do the early Land rover engine but no one’s seems to be tackling properly the 3.6 engines


JLR are now nearly £10k list for an exchange engine, utter madness on cars now worth as little at £8k.


Any one like to make a recommendation, before I scrap yet another 2006 TDV8?

Failure due to low oil pressure is a strange one on a rebuilt engine. There were a couple of threads dealing with low oil pressure earlier today. They seemed to point towards incorrectly fitted aftermarket oil filters.

I can see why it should be a particularly more difficult job than any other V8. Could you not assemble one good engine out of the engines you have?

Do any have a good bottom end? Any with a good top end and block. You have several options on each component, if you can find a good one of each one the pile of parts you have, then there shouldn't be a reason you couldn't put together a working engine?

The problem seems to be part availability hence the high cost. There is nothing that can't be fixed with a hammer😜😜

I agree it should be simple, however the challenge is you struggle to get oversize pistons and undersize crank bearings, the cranks donn't like being ground and because they are cold snapped rods you struggle to get accurate fitting bearings and that seems to be the cause of subsequent problems.

All seems strange to me given I have just had a a 1948 Pullman unit rebuilt with little issue and runs like a swiss watch, but talk to any of the old school engine builders and they run a mile from these modern units.

I know a really good engine builder who cut his teeth stripping v8s with his dad when he was 6 he has his own garage building high power skylines I'm not sure if he would be up for rebuilding a tdv8 but i can ask him if you want if he doesn't he may know someone who does L322 2008 vogue

more than happy to here about anyone who I can follow up with, so please do.

I think any good engine remanufacturer could do it for you, but it's all about availability of any broken or worn parts.

Which is why I was asking if he lumps the 3 engines together dos he have 1 good one?

If so a decent rebuilder wouldn't need parts, just time. There is nothing that can't be fixed with a hammer😜😜

Had A chat with two mechanics i know and both are too busy to do it but one did say to try Mann Automotive in Laurencekirk
as they are the only ones he knows who does them L322 2008 vogue

I know Richard so will try him again previously they declined to get involved with these Engines as most people seem to.

Thanks for the feed back.

try these
they are V8 Specialist

Sleeper, Thanks for the heads up, I spoke to them today and they will not get involved with TDV8 Diesels so no joy there.

how competent are you with spanners as it looks like it's the only way it's getting done L322 2008 vogue

It's got to be worth a go, how hard can it be.

If the engines are out, and you can assemble bits, what's the worst that can happen...... You end up with an cream crackerd engine, which is where you are at at the moment. There is nothing that can't be fixed with a hammer😜😜

Did you see it running?

If yes, I reckon this is your best ticket out of the situation. Base your rebuild on that block. The piston might be a duffer, but if its just a bottom piece of the skirt, then it'll have fallen, maybe bumped off the crank/rods and landed in the sump. It wont necessarily have damaged anything else. any scoring (if present at all) on the cylinder would most likely be below the piston ring lines, so compression would remain OK.

If it were me, I would swap out that single piston+rod with a matching piston from one of the other blocks which you think is OK. Then bolt it all back up and fire it up. What have you got to lose?

Its a running engine (you think) with a small piece of piece of metal thats been sat in the sump doing nothing. It should still run.

I used to strip and rebuild my old rover V8's. Whilst the tolerances are higher in the tdv8, I can't imagine that the general process is that much different, especially if you are just removing and refitting the same parts.

Its a pity your not closer (i'm ayrshire) a rebuild of an engine is something I would like to help you on / learn the tdv8, but I think I would get my jacksie booted by the missus!  V8 or else ...

ability I have time I donnt,hence I was looking toget the engine work done by a decent 3rd party then refit it all which in its self is no small job, I want the RR as a long term spare car, I have a 4.4 and a very high mile D3 that i would replace with this 3.6 RR, but i need to be confident in it long term and donnt mind spending sensible money on a decent engine, just not the £10k JLR want for one, I would rather sell it as is sell the D3 and buy a second 4.4.

It seems strange none of the reputable companies will take on these engines.
