V6 Crankshafts

The JLR V6 has a reputation for eating cranks, particularly diesels, how does the P380s fare in this respect have there been cases of crank failure?.

I think the only two crank related failures I have seen on this forum were both v8's. One was over filled with oil by several litres and the other was a worn crank possibly due to wrong oil or lack of servicing.

That’s good news it’s something that worries Diesel owners

Nope, there are JLR V6s and JLR V6s. The crank issue only concerns the 2.7 litre and 3 litre diesel V6 which is a completely different animal to the AJ126. I think it mainly also happened in Land Rovers with those engines.

Bear in mind that the AJ126 is based on the AJ133 block anyway, so presumably crank reliability should be similar in both cases. I'd suppose the diesel V6s are actually a V6 design, not a cut down V8.

Thanks guys it seems I raised a red herring, after researching AJ126 - 380S it is not related to the diesel at all, it is literally a V8 with 2 pistons less, they just happen to be the same capacity.

Do you actually own an F Type or currently looking? Your posts seem somewhat random and have posted no photos or signature details.

I’m looking, currently I’m thinking a 380S AWD convertible would suit best, currently we have a Z4 which gets used all year round, maybe a 16/17 car. I do as much maintenence as I can and the FType is well served for parts supply.

It's a good move from a Z4. I did the same change, as have many on here. Probably avoid the AWD if you're used to RWD as it will feel a lot less 'alive'.

If you want some help, many on here can guide or even check details of specific cars you may be interested in
