Hi there - i read through this thread and i hope others who have the same problem also get here becuase it is worth it and i must say that all the peeps who have contributed on here are legends!! Thumbs Up Thumbs Up Bow down Bow down
Our situation was that the mrs' 57 plate with 75k miles died a couple of weeks ago. We got it recovered back to dealer and confirmed casting had failed Big Cry Big Cry
I stumbled across the disco3.co.uk site and found the link here thank god!
Long story short if it wasnt down to the research of others that formed the basis of a letter to land rover i dont think our outcome would have happened.
Fortunately we had extended warranty on ours that agreed to stump up 3,6k however the balance of about 4+k was up in the air.
Credit to the dealer they did say that they would see what, if any, assistance they could get from LR and they channelled our letter through LRCS.
The result? Success LR agreed to premature component failure and that they would cover the cost of repair! Very Happy I am sooooooo grateful to all that did the legwork and cant thank you enough. The beers are on me!

Good result Diso3lee..... It was through info on this forum that I decided to change the casting during my trucks timing belt change.... The ironic thing is the part only cost £60 and yet it can cause £0000s of damage...

Your so right DiscoJoe90....... untold damage for such a cheap yet vital part. its just a shame though that there must be unfortunate owners out there that havent researched the problem and thought they were on their own so coughed up the cash to fix the problem let alone change the casting before too late. looking at the work that has to be done to put it right Shocked

Germany 2008 Discovery 3 TDV6 HSE Auto Stornoway GreyDiscovery 3

hey guys,

just stumbled over this thread here and do not really know now which was the bigger fault, buying a discovery 3 or looking into this forum here!? Bow down

bought the disco two weeks ago (06/2007, 8A442...) and just searched for some infos about timing belt change, as i need to do it next year.

after reading that issue with the faulty oilpump i do not really know what to do now!?

is the faulty oilpump visible during the timing belt change? are there definitely two different oilpumps available (a weak one and a stiff one)?

is the change big effort? Shocked

to be honest, looking onto the following pics, i do not really see any differences (just the color) between the left and right part!! no additional stiffeners, etc.!!

thx, martin

The left one is the new style pump, and the right is the old style Thumbs Up

I have highlighted the areas where it has been strengthened

It is a lot of effort to replace it, but not as much effort needed to take on Land Rover, to cover the cost of a replacement engine, if it fails...

LR013487 is now specified as the replacement for all of the D3 TDV6 engines, however during the production run there were five different part numbers used (or specified in Microcat)

to 6A999999 --------------- 1348651
7A000001 to 8A457085 --- LR002465
8A475086 to 9A508509 --- LR007131
9A508510 to 9A510121 --- LR007798
9A510122 on --------------- LR013487

Tensioner Breaking off oilpump

I do not Think the most common reason for the pump house to break is stress from belt running out the side, cams siezed, hpfp siezed or similar. Remember the tensioner is the last driven part ( the part is only Holding the belt tight, not under much tension) if the tensioner breaks it normally happens when the normally driving part (crankshaft) suddently stops, because of bearing seizure on the crankshaft, or broken crank. It might happen if the car when reversing, is put into forward gear, forcing it to suddently stop and turn backwards. Normally if any of the driven parts siezes up, the belt Will snap between the driving pulley and the siezed pulley.

The engine to stop and turn backwards when going from forward to reverse, I don't think so!!!!!!!

Well all opinions are welcome on the forum but my opinion is that nothing above is true, likely or possible.
