Hi - my car (evoque 2012 105k kms 2.0L ecoboost) started running rough - 'restricted performance' flashed up on the dash - trusted indy shop inspected car & reported timing chain tensioner failure. New chain and associated gears and pulleys will be about $1000 in parts plus labour. IMO, with a relatively low mileage vehicle (105k kms) that always had scheduled oil changes etc, its disappointing that the timing chain assembly needs changed out... I guess it's also age related as well as miles. So my thinking at the moment, this time I got away without damaging the valves and pistons so get the timing system renewed now and dont take any chances. Hopefully be good until 200k kms.

My daughter has LR2 with same engine (2014 100k miles). It's important that she has a reliable vehicle so am thinking about proactively doing the same to her car (renewing the timing assembly). It's expensive but I live abroad at the moment so I cant help her easily if she has a problem. The car has always been maintained (oil changes etc), but I'd like her to avoid any distress and at the same time avoid a disastrous timing failure that wrecks the engine.

I was hoping that regular oil changes (5k miles - synthetic) would prevent this type of failure but its not the case for my Evoque. Any thoughts about this proactive maintenance for the LR2 - overkill?
Thx as always

 

I'll do that kind of proactive mx on older cars which I use for road trips.

Cooling system at 150k miles, timing chains and associated hardware.

If yours failed at 105K km, and your daughter's is at 100k miles, sounds like it might be time.

Not sure why a timing chain would fail on age though. A belt will age out because the synthetic plastic will degrade but a metal chain should just wear based on miles and oil interval/quality.

 

It appears the 2014 LR2 uses the same engine as the Evoque (I am assuming you have a turbo model). There is no service interval for the timing chain or tensioner. $1000 is somewhat below the average for the cost of repair/parts.

 

In fairness - it was the tensioner that failed (spring component), not the chain - if I was a bit braver I'd just replace the tensioner but as stated, trying to build in some assurance of reliability. Yep, the data supports proactively changing my daughter's car. Needs another turbo too.... grrrrr

 

Yep engine is same - LR2 & Evoque - Turbo

Parts:
Dayco VVT hubs - $200 ea ($400)
Chains + tensioners - $400
gasket + oil + filter
Approx $1000 total - so seems OK

BTW - Saw some way cheap kits on Amazon - ($135 everything.... no reviews though... I'm not brave enough for this kit but if I was back home I'd definitely think about it)

 

Those numbers don't count labor. Mech has to eat too. And with things like timing chains and tensioners I would not even remotely consider any cheap Amazon kits. If it fails the wrong way it could take out the engine with it.

 

Make sure you review the forum for the restricted performance commentary. There are other solutions to make it go away that were not timing chain related and much less costly.

for example, on my 2014 LR2 it was this:

Not all service technicians are correct.

 

Imagine... using a hose to route hot, pressured exhaust gases. Like nothing will go wrong there.
I had a related issue, the turbo itself was cracked.
Many jump the gun and assume that the root of all causes is the timing chain; not realizing that its a Ford ecoboost engine in the LR2, and not an ecoboost in the LR4. Moreover the timing chain tensioner and chain in the LR4 had a significant engineering change early on... but rumour and innuendo still have many thinking the early solution is still in play in the later models.
To keep the timing chain and affected parts in good order, keep on top of your oil changes and use the correctly spec'd oil.

 

Maybe. But there's a reason for that old saying "You can't fix stupid... you can only stun it with a 2x4 until the next model year."
