Oil Pump, new thing to worry about .

[Fatso]

Been reading on the net that the oil pump on 2007 discos and RRS td6 seen to have a problem where the oil pump housing which the Timing Belt tension-er is bolted to can actually brake off due to the pump housing not being up to the job :eek: , thus mincing the eng .!! Not sure of earlier or latter models but seems to be the 2007 most mentioned .

This usually seems to happen after the timing belt change out , apparently this can be fixed by fitting a latter model oil pump that has a beefier section where the tension-er fits onto , not sure if this is the result of bad fitting of the tension-er when renewing belts or is a genuine manufacturing problem :confused: . , can anyone throw any light on this so i can sleep at night .

Work at a dealer. Never seen this happen. Never heard of this happening.

Doesn't mean it can't but I presume this doesn't happen very often.

I was just looking on the disco3.co.uk site and found it while looking for other info , it was under cam or timing belt tension-er broke . I think most of the failures/myths on the tinternet are the results of thrashing the machine or bad maintenance and then it is put down to landys are on the nose . :mad::mad::mad::mad:

Still the best car i have driven :D:D:D:D

Does happen....$12000 later.

My mate owns the vehicle, I know the history since new and I wouldn't say this vehicle was 'abused'

I have the remains of the engine in my workshop which we are going to pull the heads off to see the internal damage. Diagnosed as broken cam belt tensioner = hole in piston, bent valve, no oil pressure.

Small amount of research suggests LR changed the design of the oil pump housing 3 times in 2007.

I think they were onto something :eek:

Hi , are you saying that the oil pump had broken off taking the tensioner with it causing the above damage or a broken tensioner fixing bolt ?. Feel sorry for your mate $12k is a lot to have to spend if indeed it may be weakness in design of the oil pump .It would appear from the uk site that most of the failures occur after a timing belt change .

another reason to stick with the V8 petrol version?:wasntme: just asking...but it seems that on a 'whole of life' cost basis the petrol versions are cheaper to run/maintain than the diesels....

That also seems to be true with the 3/4 ton pickups over here. Fleets are switching back to petrol engined pickups from diesel as the life cycle cost, (purchase, maintenance, fuel and resale), tends to be less.

I have read there is talk of a new Discovery having the direct fuel injection 3.5L Ford EcoBoost twin turbo V6 that appears successful in the F150 pickups over here. Guys who drive the 3.5L F150 boast about the V6, (not the norm when a V6), so they must be working OK here. Apparently they feel fast, have good acceleration, and fuel economy is unusually good for a pickup, real numbers like 10L/100km, (23 miles/US gallon) with 365 hp and 420 lb-ft of torque.

All good till you want to go bush and there is no petrol AND is illegal to take it there.

Here are the photos showing the external damage.

Ouch , that looks the same as the failures in the UK usualy after a cambelt change , do you have a gut feel for the cause of the failure as the brits never realy came up with anything other than the pump was not strong enough around the tensioner bolt on area and change out the oil pump when doing the cambelt . Can only be something unusual as the majority of vehicles are not effected . My belt change is due end of 2013 .

[CaverD3]

Given the discussion on UK site it is a small number of MY07 vehicles that have a different design housing. Good precaution to change the housing with cam belt.

Do we know of any build dates that are effected as I have a Feb 07 D3

BUMP on that last question - I will be doing my timing belt as early as this weekend so I'm wondering if there's a vin range

Does anyone have a link to the UK discussion?

Thanks in advance!

I did manage to find this website which shows the difference in the pump design.

The Uk website is , disco3.co.uk , would appeare to be around the 2007/8 model but it has happened on ealier modles as it has the same oil pump .

It appears to happen mostly after the Cam belt change , my gut feel is bad workman ship when changing the belts , seems strange that the problem has happend to only a few vehicles after the cambelt change and not the 168000 Ks before , ( not the 100000 Ks as mentioned on the website you looked at ;) ) . But who knows .

If your changing the belts yourself you will be able to have a good look at the pump when you change the Tensioner out .

I have an MY08 RRS - the VIN series are different but I'm assuming the engine will fall into the same category.

Has anyone here replaced the oil pump or had this happen to them? I'm always a fan of preventative maintenance.

I have been quoted $550 for
-both timing belt kits
-2 rollers
-air filter
-Acc belt

Also had the alternator let go with a nice burnt smell and a battery light today. Idle voltage = 12.8v. $330 for a JAYLEC alt or $650 for the Denso job. So hoping the battery will get me back home (15k from where I'm parked) otherwise I'm going to need a tow as well :no2:.

I have read through those links - thanks d3viate for posting them. I also called our local LR dealer (Solitaire prestige), the service advisor said he hadn't heard of the issue and noted that they do hundreds of timing belts over all year models. I am tending to agree w Fatso in that possibly the bolt is being done up with too much force and weakening the metal, causing this failure. Looking at the figures however it would suggest that as many failures are occurring on the 05MY as 07MY. I will definitely inspect the integrity of this part when I have it all apart this weekend or next. Meanwhile, fun with this alternator.
