Hi guys my 2006 LR3 ( discovery 3 2.7 tdv6 diesel ) decided on Friday to break it's crankshaft- no warning other than a grinding noise just before I pulled up. Recovery driver took a look and stated crankshaft broken. All fluid levels where correct. Apparently this seems a problem LR know about and have in some places recalled vehicles. Not so in UK and Irelandnow faced with euros 10k to repair with only a guarantee for 10k kilometres. I believe later models were modified to prevent this but unsure of the year LR did this anyone know.

Have a google, 2.7s very rarely snap the crank, it does happen, what normally happens is the oil pump casting fails right where the cam belt tensioner bolts on, this then means belts and timing goes out the window.
Early cars up to 2007 are normally okay until the belts are done then the mech over tightens the cam belt tensioener bltl, this then starts of the oil pump casting failure which fails shortly afterwards, most seemed to be weeks or a couple of months afterwards before they spat their dummy out, 2007 onwards D3 are at highest risk and need oil pump changing asap if old type fitted.

They then enlarged the engine to 3.0 and added 60 bhp this now means the cranks snap with no warning whatsoever! on some cars with only delivery miles on, others do many 1000s of kms with no issues, I think they changed the bearing shells in 2016 to stop the ctnak problem, but rumour has it the engines are still failing in the D5/Range Rover, basically anything fitted with the 3.0 v6 diesel.

So you need to confirm its snapped crank or snapped belt tensioenr before deciding what to do, as if it belts you may be lucky and get away with two 2nd hand heads new oil pump and some belts/gaskets, if crank its had it.

Slight aside, is this problem still prevalent on the 3.0 in the Disco 5 or have they sorted it?

I have read/heard its still an issue, any vehicle with the 3.0 litre diesel is at risk, as time goes on unless someone can come up with a fix this is going to seriously dent their sales/image, bit like Audis old multitronic gearboxes, so bad many 2nd hand car dealers would not touch them!
They are also having loads of issues with the ingenium range of engines.

Read the other day the best one out there is the very late FL2 with the 2.2 4 pot diesel.

I think all car/van/truck makers are struggling at the minute and its all to do with emissions.

LYNALL As stated in my post crankshaft broke so it's a new engine or reckoned one. It also is happening to citeronC5/6's and to Jaguars but JLR aren't acknowledging the problem though in other countries such as China and Australia recalls have been issued. Moral is buyer beware in fact buy a defender or something else
 
Llnall As stated in my post crankshaft broke so it's a new engine or recon one . It is also happening to `Citeron C5/6 and to Jaguars fitted with the tdv series engines ( also known as Lion )Jlr aren't acknowledging problem though in other countries including China, South Africa and Australia recalls have been issued. Moral is buyer beware in fact buy a defender or something else altogether.

The recall abroad has been out for some time and Iirc applies only to the 3.0, but no one actually seems to know what the techs are actually looking at when the cars go into the garage?
 
The Ford V6 is weak.

Best source is an S Type as they seem to last better than D3.

When I got my D2 MOTed sitting on the counter was a snapped crank!
 
Lynall, with all respect I suggest you type in 2.7tdv6/8 engine problems and you will find that the recall actually applies mainly to the 2.7tdv6 with the 3.0 version also being recalled. It is also occurring in the USA but JLR haven't recalled any vehicles there yet although there is mounting pressure over there for them to do something.I also respectfully suggest you look at You Tube where you will find the resulting broken crankshaft. To replace crankshaft is a body off job and I mean complete body off that is why replacement costs are high.

Think you will find broken crank means new engine, as the crank damages the block and it cannot be trued up again.

On the D3 forum its now very very rare to hear of 2.7 crank failures, yet 3.0 crank failures are not quite a daily affair but certainly two a week.

It is only in the last couple of years that you can now get new engine parts for the 2.7, now they are everywhere and prices are still dropping in line with the cars values.
Iirc there was a shortage of cranks for quite some time
 
Half of the problem is that the people who are now designing engines no longer wear tweed jackets and smoke pipes. Instead they are highly educated CAD wizards glued to computer screens.

When I were a boy me and my fil spent our days welding up hgv trailers for inspection or mot, these days to see one cracked is almost unheard of, all I assume down to the CAD boys and stress anaylsis?
Either way its great as I dont have enough spare hair to lose any!

To be fair Ford had little to do with making the Lion engine, there was just a joint venture with PSA on it's design. It's essentially a PSA made engine, with its components made in the PSA manufacturing facility at Trémery France.
The Lions going to JLR are or were assembled in Dagenham, but I'm not sure that's still the case. The whole manufacturing could well now be done in France, alongside the engines destined for other PSA vehicles.

It was the Dagenham bit

I think the real problem is that the whole process is controlled by accounts, TD5 engines can do astronomical mileage with a bit of care.

Most UK built engines do high mileage without a hint of crankshaft failure. This doesn't seem to be the case with engines made elsewhere.
