TDV6 crank and crank bearing failures

Also a common(ish) issue with SDV6. Repairers (particularly LRA), will always look to lay blame on other factors that may or may not of caused problem...

Note: general statement, not specifically targeted.

I’ve been looking at the protruding air flow “increaser” (protruding element) that’s removed when you want to use the recovery point, and it’s not insignificant. It’s removed by both bull bar installations and under trays such as APT, and it’s impact to air that enters the radiator would not be insignificant. Without it a significant amount of air would find it easier to pass under the vehicle than being “trapped” and forced under the vehicle.

I understand a number of factors have combined to (potentially) cause this failure, but I can see how this element impacts cooling performance.
Conversely crank failure is unfortunately common (common in the terms of it just shouldn’t happen) in this vehicle, and it does feel like this engine is living on the edge and doesn’t have enough contingency built into its design.

All that said, I’ve reviewed the factory bull bar and while it does have an element of protrusion, I question how much and whether it’s much improvement than aftermarket.

Awaiting flaming

Have you asked any questions of the engine tuner?

I assume that the reason these are never repaired is the cost of parts (if you could get part numbers and supply) and that lack of any method from the factory in the form of a workshop manual with rebuild instructions? It’s the first car (I’ve) come across where this isn’t possible.

Will certainly be talking to lra next week

Is this engine only cost?
Is this the new from LR price?
It must be possible to find good second hand from wreckers or eBay noting how many wrecks there are displayed (triumph spares)

In general a good transplant should beat a rebuild cost unless you are doing labour yourself (assuming also kits were available)

Total cost and is a second hand motor with low ks and warranty

Lets hope this one doesn't spit the crank out as well.
Are they going to drop the sump on the replacement motor to check that it is all good to go or are they just going to chuck it into the truck and hope for the best?

Too many of these go pop. One fairly recently just before or after its 1st service. At 116,000km JLR should cover most of the cost. The motor properly serviced should last much longer.
