    Yes it's a 2006 SE, I just put a set of factor rock sliders on. It has an aftermarket in dash Pioneer but other than that everything else is stock and I always try to use genuine LR parts. Keeping my fingers crossed every day!

    LR4s can apparently get to at least 300k kms. This one has: 308k kms (192k miles) Capture.PNG

    I had a 2004 Discovery (loved that car) with 120K miles that developed a very similar ticking sound. Would not tick when cold, only after it warmed up. Took it in to my local Land Rover dealership (Just kidding there is no such thing as a "local" LR dealership in the states. I have an hour and a half drive in either direction to get to one.) Unfortunately it was diagnosed as being fatal. Apparently the cylinder walls are lined with a sleeve and one of the sleeves had dislodged and was slowly sliding downward. I was told it was irreparable unless i wanted to replace the engine at about $10K +/-. I was also warned that I should consider not driving the vehicle long distances as after long distances the cylinders would naturally expand from the heat and encourage the sleeve to slide and at some point drop down far enough into the engine block and potentially blow out the bottom of the engine. I traded it in soon after that at a Mercedes dealership on a cold snowy winter day. By the time they got around to inspecting the car it had cooled enough and as it was still snowing slightly they weren't too interested in taking it for a test drive. They just started it up and listened for a few minutes. It purred like a kitten. Had a Mercedes for a year and traded that in for a Range Rover. It's good to be home!

    Here's another video to add to the list. This is my 2011 LR4 with 78.5k miles.
    LR dealer claims it the timing chain and tensioners.
    Independent shop said that it was a little loud but nothing to be worried about. I took it back to to the indy shop for a trans service about a month later and he said that he took another listen and now also thinks its the timing chain and tensioners.

    Thoughts?

    That sound seems to be lower in the engine than the cam timing unit. Again I would use the long screwdriver/socket extension method to figure out where exactly it's coming from and go from there. I have zero experience with the 5.0 but the 4.4 definitely has variable valve timing and that's what's causing the tick on my LR3. Still driving every day...

    Once I get it back from the dealer (it's now in for transmission replacement, yikes) I'll definitely have a listen with the long screwdriver and report back.
