    AJ133 5.0 N/A full rebuild

    Hey guys n gals
    First off I'm in the States now, moved here from St Annes, Lancs in '99
    I have a 2011 LR4 with the AJ133 in it, that I picked up for a friend, and a '11 SC Range Rover that the missus drives. The friends only needed the timing chains and cam phasers, then he touched it....
    The result was 2 pistons that decided to say hello to the exhaust valves when he pushed the start button, for some reason.
    Engine is out and stripped.
    I'm hitting a brick wall regards ANY specs on the bottom end though. Everything I have just says "part of short block". I use Alldata for everything we have, all LR's, and have never seen this before. I measure the end float before pulling the crank, but couldn't find any specs on it. Machine shop is having the same issue after I dropped it all off for them to double check cylinder runout, hone the bores, polish the crank, and so on. Zero information
    Also having a heck of a time locating engine internals. Pistons, ring set, rod and main bearings, etc.
    This forum came up on a search where a member did a rebuild, but again no specs listed in that thread. So instead of hijacking his thread, I made my own.
    Any and all help really appreciated
    Here is the carnage. Cylinders untouched if you believe it!

    Hi Martin.

    I can't read the whole thread over on the US forum as it's long, however, there is a chap called Dave Tibbs who knows his stuff. Have a read and you may find what you are looking for, or, get in touch with him.
    Here's the link and I hope the mods don't mind this kind of help; https://www.jaguarforums.com/forum/x...ebuild-177468/

    The thread by Dave Tibbs is a great read for engine builders. I may be wrong but I thought car manufacturers had a legal obligation to make spares and information readily available for their products. Seems to be difficult in the case of these engines.

    Reading that thread taught me that some 5.0 V8's have a crankshaft pulley bolt that tightens clockwise and others anticlockwise, a total nightmare and massive expense if you don't know beforehand.

    Looks like the owner is going to go with a replacement used Jag engine.
    They are a few thousand less than a LR variant, and about the same savings on a rebuild.
    Oil pan, pickup tube, and manifolds are what I see needs to be swapped. Then install the LR sensors etc.
    Do you have to mess with the timing to swap oil pans?
    I only pulled the old motor apart, then left out for work, so cant look it over.....

    Thanks!!
