I have a 2015 and had the dreaded turbo failure that most of these seem to have at some point. Mine failed just after the warranty was expired (around 51-52k). I purchased an aftermarket replacement with a cast iron manifold because I didn't want to spend $2000-$2500 for a LR one and then have the manifold crack again in 50k miles. Everything was good for about 9 months, but I was rarely driving it since I was now working from home. But a few months back I noticed I had an oil leak making a mess on the rear of the plastic panel the covers the bottom of the engine. I finally got around to checking it out when I changed the oil and I could tell it was coming from the turbo because there was oil dripping off of the bolt head of the oil return line and one of the coolant lines.
I thought it was possibly the upper oil supply line so I put new copper crush washers there, but it was still leaking. So I put some dye in the oil and cleaned everything real well, then put it on the lift and started the engine. After about 15 minutes I saw oil starting to run down that area where the clamp connects the manifold to the turbo cartridge. You first see it whee the red arrow is in the picture. It then runs down and then out on to the oil return line and then drips off of that. I am assuming it is the oil seal for the turbine shaft. The upper oil supply line to the turbo is completely dry. Does that sound right? Anything else it could be?
I'm hopping I can leave the manifold on and just take off the cartridge (the center part where the oil and coolant attaches and has the bearings and oil seals). This would mean I wouldn't have to remove the exhaust, downpipe, and drive shaft, which was the most annoying part of the replacement. Anyone ever done this? I have never seen just a cartridge for sale or even the cartridge with the turbo housing. It always comes complete. Should I just get it rebuilt by someone?
