Thread: Tensioner snapping off the mount TDV6

Not a lot of help I guess but they are rebuilding 2.7s in the UK - often the pistons are undamaged (but sometimes they are) but the heads, valve gear and timing chain will need replacement - not a great job but apparently has been done a few times. If interested in this option have a look and a search on RRSPORT.CO.UK • Index and DISCO3.CO.UK - Index

They have acquired engines that had failed cranks cheap and used the top end - one guy even used a couple of pistons as well.

Good luck

Was it the first or second belt change? If first it was well and truly overdue so you obviously knew this needed doing ASAP? Assume you negotiated the belt change in the price?

Did you buy privately or was work done via the selling car yard? Was the workshop LR experienced?

Anyone you can go back and have a chat with or push on their or your insurance on basis that excessively torquing up the tensioner led to the failure i.e. it was perfectly ok up till then. That’d be my angle with said repair shop. Worth a crack.

LR D3 TDV6 SE MY07 Off Road Touring & Towing Vehicle *ENGINE DAMAGED - NOT RUNNING*

Had new serpentine belt and tensioner fitted at same time engine timing belt done.
1500K's later driving and thought the cross wind must have been strong as steering got heavy....then temp went up.
Found that head had come off the tensioner for the serpentine belt, all belt functions stopped.
Seems enthusiastic mechanic may have either not fitted new bolt with tensioner, OR overtightened bolt, partly breaking head, which later dropped off.
Found the bolt head on the tray under motor when I went to change oil next and it looked like it had been half torn off when being tightend. (overtightened)
SO new bolts always with any new tensioner and make sure not over tightened.

Sad to hear about cost of new motor.
Good Ford Territory 2.7 motor can be had for under $6k and also fits (same engine, change front pulleys and sump).

Paid $19k and apparently $17k to get another LR motor. PS I am a newbie and so forgive me lack of understanding.

Just got a quote of TRS in Adelaide for replacement engine for a D4 SDV6 with low mileage came in at $13750 + $250 for freight to Sydney on exchange basis not sure of kms but did ask for low kms, includes 'a long engine with turbos injectors & H/P pump for $13750. freight $250 exchange'.

This was for another project D4 on gumtree at the moment selling for $8000 2013 model with high kms but by the time you factor in engine, transportation from melb to sydney for D4 came in at $1272 plus labour costs just not worth it. Think its a body off for engine swap. You can pick up D4's from $20k. Shame these late model vehicles are just not worth fixing up UNLESS you can get a cheaper engine + do the labour yourself. FYI.

I have been lucky so far with any "failures', but I have always changed my engine and fuel pump drive belts and tensioners at 160K or a bit sooner if I am near a service option.
Last front engine belts and tensioners done at 120k and noted that the old tensioner appeared loose to turn, so not sure what that would have been like if I was waiting until the 160k.
Have had tensioners for serpentine belts get noisy and need changing after only 40,000k.
Possible that manufacturers (LR UK) are aware that optimum life of tensioners and belts may not 160k, but to suggest more frequent chnages may increase listed running costs and make them look more high maitenance than their competitors, so they gamble with the chance that only some will fail if they suggest and extended change period.
EG: The same reason that transmissions are marketed as "sealed for life", which greatly reduces the listed running costs of the vehicle and possibly makes it more attractive to the naive purchaser (who belives that transmissions are indeed perpetual motion units).

So we got a 2nd hand 2010 LR Discovery Engine fitted.

Drove to Gold Coast with 1.7t Caravan and twice on the way up we got the engine fault error limp mode. Stopped turned on and off and it was cleared. On the way home it happened once. We also got transmission fault error message. We eventually got home but we will need to take it back to Canberra. It was a bit frustrating for us , just want it to work after spending the $8,750

I bet you got those engine faults when you were putting the boot in when towing or placing the engine under a bit of load like going up hill with a bit of power on - as you indicated it is cleared as soon as you switch off and back on.

If you do a search back through the forum on here you will find it quite common as seems to be a "design/software" issue rather than any physical issue.

With my RRS the car drives fine but as soon as I tow the camper the fault you describe starts but only when I call on the engine to deliver lots of power under load. I have learnt to live with it and I assume the ECU software reads a manifold pressure that is different to that is expected when under high load like when towing with foot to the floor. I have also learnt to put the car into neutral, switch off and restart on the road to clear the limp mode - obviously when it is safe to do this rather than stop.

When I tow I have also learnt not floor the accelerator and the issue does not arise.
