The drain pipe pictured is not the L322's original, single drain nor the replacement twin drain. The pictured drain has 2 outlets from a single drain from the turbo and has a clamp fitting to the block whereas the twin drain uses a piece of hose with hose clamps for its higher-up outlet. Hence the turbo failure can't be attributed to a single drain.

I'm not so sure that the right-angled corners are the best design for oil that has to fall away from the turbo with minimal resistance though.

Has anyone a photo or part number of what I need to have it changed for?

Your old engine's drain was already a twin drain, just a different style to the one applicable to engines made before the 2nd drain was incorporated when the engine was built. Your twin drain can't be fitted to earlier engines and vice-versa because your block had allowance for the 2nd drain when manufactured, as evidenced by the press-in fitting and single retaining bolt.

I suspect that your vehicle's vin is higher than 160137, the upper limit mentioned in TSBs for smoke and DPF problems caused by the single drain.

Regretfully turbo oil feed seals (comes with pipe) are not available from JLR till November 30th so it’s going to be off the road into the 8th week.
If anyone has these please let me know.

Regards

I assume looking at the workshop pictures it is an approved service centre rather than main dealer in Suffolk doing the work?

Unfortunately the seals wont last and will have to be replaced with Viton seals in a few years, along with the oil filter housing gaskets but maybe LR will be providing gaskets that withstand the heat by that time.

Edit: If you're paying for the new seals/pipe then you could ask to have BS611 Viton seals fitted, sourced either by the repairers or yourself from a bearing and seals supplier.

8 weeks on Saturday and have only just got the replacement oil feed pipe with copper seals. Engine can at least start to go back in. Still waiting for some other seals and if they arrive should get the car back at the end of next week.

It was the right turbo that failed , left hand side looking at front of car.

In case anyone missed it, this is the primary turbo.

My throttle closer has been fitted for 2 weeks and today one was fitted to my son's 3.0 D4. 2 will be fitted to my brother's 3.6 TDV8 RRS in a few weeks, 1 for each butterfly. It closes the throttle butterfly for 30 seconds every time the ignition is switched off to ensure that a runaway engine will stop when the ignition is switched off. Its a pity that LR hasn't programmed this simple action into the ecm.

Nice one Graeme, any pics?

I did miss that this was the primary turbo. What's interesting is that the drain mod relates to the secondary turbo, so OP has nothing no do with whether you have had the drain mod or not. Reassuring for me and anyone else who has not had the mod done.

Hope you're back on the road now or very soon Richard.
. Cheers, Greg

Did you spot that a twin, factory-fitted drain was fitted to this vehicle and therefore contributes nothing to the single/twin drain discussion?
