    Granted, it's from a different car, a D1, but the principle is the same:

    From what I can find, it seems LR recommend 24,000 k intervals, while for Ford it's 30,000.

It not my field of expertise, but every engine I have seen ranging from a little 4 pot that was in a datto 180b I used to own right thru to the 35ltr cat engines in the boats I manage all have the tangs on the shells .

    given L/R past with things like oil pump bolts not loctite'd and a few others , I would have thought a tang to locate the shells would be a good idea , but, I guess the idea of saving a few $$ where ever they can wins every time .

    The bearings don't wear on the 'tang' side.

    Also, if the crankshaft grabs a bearing then nothing is going to stop the bearing from spinning. The forces involved are just too great.

    Thanks - I fully understand that , but every time I have seen it done , or , done crankshaft shells the tangs are on opposite sides and the cap when placed in position has a flat surface which buts up against each tang and locates them into position, it seems I assumed incorrectly that this served 2 purposes 1 to locate the shells and 2 to stop them being able to spin as they are sitting against the opposing flat surface, and not blocking off the oil gallery .

    Cheers Ean

    So if there are dodgy build processes on the engine it is a Ford issue not LR.

    Ok,sure,but are there failures in other brands that use the same engine?

    They pop up on the Jaguar forums. But, as one guy I read says, "There are a lot of 2.7's out there in a wide variety of PSA/LR/Jag cars, and you only generally hear about the ones that fail, rather than the ones that are still running fine at x,000 Miles...."

    I can't help but wonder if this is where the problem lies . I know oil has come a long way , but unless we do a major trip , our D3 would struggle to do 4000ks a year. Personally I think even running the same oil for a year can't be good on a engine that has EGR , but plenty say synthetic oil can cope.

    Its just the way my brain works , 5 ltrs of oil trying to run for 24,000ks in a environment that pumps a % ( even tho small ) of pollutants back into itself. Personally I am happy to put new oil and filter every 6 months or 10,000ks even if people tell me I am wasting $$.

    Friend of a friend just sold an 05 D3 TDV6 S with 280,000km. He’s had it since new.

    Had not even replaced the timing belt!

    Gearbox was stuffed needed rebuild.

    God knows what the oil change history was.

    Got $6k for it.

    Bought a new D5!

    The other thing to take into account is that the failures are not in the crankshaft main bearings, as I understand it, it is a conrod big end bearing about 1/3 from the front (not sure which piston) that grabs the bearing and spins it etc but that is not normally detectable from the drivers seat - this fatiques the crankshaft journal at the big end and the crankshaft breaks (not sure if this is instaneous or takes time). Seems to happen like this in most engines that have actually been checked - if all engines were checked before being scrapped an different result might show up.

    So the $64,000 question is what makes the engines fail at this point - why is this the weak point? And why some engines and not others - if it was a design issue then all engines would be failing which they are not (only a small number) - this leads me to the bad maintenance theory or the bearing caps not being tight on some engines.

    I have reduced my oil changes from 12,000km to 10,000km and always use the right fully synthetic oil and in view of some reported loose bearing caps considering whether to get the sump dropped and the torque on the bearing caps checked - not undone - just torqued to the correct amount.
