2.7 and 3.0 Td V6 Crankshaft Bearing Failure known manufacturing fault

Well, it's been over 12 months and well over 20k since the new engine went in. While I can't say that I'm glad it happened I am thrilled with the drivability of the new engine. It's power delivery, it's torque and acceleration are incomparable to the original engine. It makes me think that there was always something not quite right with the original engine. Even towing a camper trailer is much less effort. After a recent service the mechanic asked about the "tune". I told him it didn't have one, and if it did I would have got him to do it.
There has been much discussion over a forged crank over the original hollow crank and how a forged crank wont stop bearing failure. While exploring various avenues to replace the original motor the one thing that kept coming up was that hollow crank shafts flex or torque, wedging the big end bearing and dislodging it leading to it's failure. I do know that high performance rotary engines, as in race engines, can and do flex the eccentric shaft and cause catastrophic failure of number 2 rotor so it sounded logical to me that the same could happen on a high compression diesel engine. Be it true or not on the Land Rover 3.0ltr twin turbo I don't exactly know.
But to sum up, the new engine is a gem and I am really happy with my decision to put the rebuilt engine in.
Thanks all for your feedback.

You would think so.

Ford Territory and D4 2.7;don’t seem to have the problem,but no where is it documented why.

Many have wild guesses,but there are no facts.

I heard about these problems a while back and was concerned because I run a Territory diesel.
Haven't seen any mention on the Ford forum (but I haven't visited for a while).

Great engine that seems to have had a problem with a certain batch and/or poor servicing causing problems. How Land Rover handle the engine failures is the issue.

The engine is a great engine .. as long as it's working!!
There have been many owners who have maintained the vehicle correctly and have still experienced this MAJOR problem.
The fact is ... whilst the motor is good with regard to performance .. it is POORLY designed in the use of materials.
Whether that be the crankshaft .. the bearings .. the turbo's or the cracking 'plastic' air intakes ... ALL of which are VERY EXPENSIVE to fix.
JLR should be held to account and made to cover, at the very least, the KNOWN and DOCUMENTED manufacturing faults.

The 3.0 Ltr engine I got was from NWS Motor Services in the UK through Jason at Rova Range in Bentleigh. The original quote was $25,000 supply and fit. I opted for a billet crank, replaced coolant hoses (OEM), serpentine belt (OEM) and replaced that plastic coolant thingy with an aluminium unit. Also replaced a couple of valves for the air pump, replaced the battery. So there is well over $4,000 in "extras" The final invoice came to $30,460. It has done over 10,000 k's and seems ok. Been off road and spent a couple of days in Low range and it's doing everything it's supposed to!! Chewed through the oil at first, well, hardly chewed, it used approx 700ml at first but that seems to have settled.

I am happy with my decision to get the rebuilt engine. When I first started looking for a second hand engine I was quoted $17,000 for a 115,000k engine and a further $5,000 for fitting. That with having to replace timing belts either straight up or in another 50-60,000ks, and it was a no brainer for me at least, but obviously not for everyone.

Nice to have a 'spare' $30,000 just sitting around.

In a few more years they won’t be worth fixing,unfortunately.

Unless one can do it themselves,or have the 2.7 which the Territory engine will fit.

Doesn't seem to be a problem with the engine in the Territory.
I know there are some differences but why are all the major issues with the engines fitted to Disco's, were they before the Terri ?

We have one at 250K and another at 130K, not huge Kms I know, but the only engine issue has been with work carried out by the dealer which they rectified at their cost.

I had a similar chat with the fuel injection guys when I went to buy my new HPFP. "So, you say you sell a few of these for Land Rovers. Do you see the same failures in the Territory?". "Nah mate, they're all soccer mom cars. They get rooted by being filled with and run on ULP long before they have a chance to get old enough for a mechanical failure".

He might have had his tongue in his cheek, but it didn't sound like it.

Tongue in cheek I think.....

A lot are used for towing caravans round Australia (from when I used to frequent the Ford forum). I did see EGR problems talked about but personally the engine has been faultless and it's driven reasonably hard plus has towed overcapacity quite a few times.
