D4 SDV6 turbo with an oil leak

[mg1970]

Hi all,
just had a major service done by JLR on my 2015 D4. It has quite a nasty oil leak on the LH turbo - I’m assuming it is the compressor side. They want $6k to replace it with new parts (ex UK so might take a while) so I didn’t go ahead straight away. I can buy a genuine LR turbo for $2100 and then find someone crazy enough to take the job on. Or take it to a aftermarket workshop that specialises in LR. I understand it is a job that requires lifting the body off the chassis.

Any thoughts?

And I’m guessing the big risk is that the oil dumps completely out of the turbo one day and causes a catastrophic failure?

regards,

Martin

From memory the LH (passenger side) turbo is a body off job, simply no access between the body and engine to get the thing un bolted.

If the oil leak is from the turbo drain line, it's just the gasket there that needs to be replaced, THAT can be done body on. If leaking from the hoisuing of the turbo, I suspect the sleeve bearing in the turbo is gone, so either a replacement turbo, or a new bearing sleeve, either will require the turbo out of the car for rebuild/ replacement, so back at point 1.

I don't believe you would lose all the oil,like on a front crank seal failure,.

Thanks,
I understand that the leak is from the turbo assembly not the oil line. JLR have quoted $10,200 for the job (new turbo + labour). A non JLR workshop has quoted about $9k (using a genuine turbo). It is the LH side turbo so yes, the body has to come off. So my 96 month service plus a cam belt went from $5500 to about $21k with the turbo, drive shaft centre bearing, brake rotors and some new hoses and O rings. 😬

So their (I assume JLR) quote went from 6,100 to 10,200? Any reason provided for the ~67% increase?

I believe they charge about 160-170/hr, so at 2,100 for the turbo supplied, your looking at about 50h labour to get the job done. Not entirely unreasonable, but it's a crapload of money for what is essentially a bolt-off, bolt-on exercise.

If your handy with a spanner, the brake rotors, cente bearing are relatively easy, the cam belts not so much, I'd leave that to the experts.
