OMG Thank you for posting these 4 videos. I'm in the process of doing chains, coolant pipes, water pump, hoses, etc on my wife's LR4 and your 4 video series is the best and easiest to follow.

Glad to help

Thank you so much. 🙏🏽

Fan of this whole series. This is very informative and deserves more views! I am thinking of buying a used XF with the AJ126 engine. Just out of curiosity, how many miles is on this when the timing failed? And would your recommend the XF in general? How is the build quality?

[@NiXFiX]

Thank you! Unfortunately higher skill stuff tends to get less views. Things more people are willing to do themselves (battery replacements, oil changes, brakes, etc.) tend to get more views. Anyway, it had pretty low miles, only 65,000 when it failed. It is important that the engine has the updated timing guides (with the steel pin I talk about in one of these parts). The factory started putting in the new design timing guides at some point, but I don't know when exactly that was. You could probably look that up though. I would recommend the XF from a fun driving experience standpoint. I like the way it drives. As far as quality, Jaguar and Land Rover are not known for reliability like Toyota and Honda are.

Hey im trying to fix my 2014 Range rover 3.0 Sport engine and have run into piston/walls damage. Do you know if the Jaguar 3.0 is same block/heads? Im seeing lots of wrecking yard sellers saying only LR4 or Range rover engines will fit my Range.

[@inspeedhunterwheelalignmen3122]

Very pro video. Just wonder why diagnostics where pointing a problem with different bank?

[@NiXFiX]

I might've had my banks backward when explaining generalities at the beginning of the video. In the end, the codes were for the bad bank.

[@macariorodriganez1477]

Great video! How many kms has?

[@NiXFiX]

65,000 miles / 105,000 kilometers

Where did you find the manual for this rebuild? I am doing a 2017 range rover sport 3.0 supercharged engine and trying to find the AJ126 manual…

[@NiXFiX]

Hello Christian! That's crazy to hear as I have a 2016 Range Rover Sport with a 3.0 SC AJ126 that is in line for an engine rebuild as well! Before that, though, I'll be doing a 2016 Discovery Sport 2.0L AJ200. I'll be making videos of both of those. As far as a manual, I'm using a 2010 Jaguar XFR manual which is for the AJ133 (V8 version of this engine). If you would like that, I could send it to you. Just reply with your email and I'll send it. Another option is subscribing to topix ($$$$): topix.jaguar.jlrext.com/topix/vehicle/lookupForm

How did you move the fuel line on top of the passenger side valve cover out of the way? The workshop manual says to remove the line you need to remove part of the subframe but it looks like you were able to sort of bend it out of the way so the cover could be removed.

[@NiXFiX]

After it is disconnected (17mm) from the fuel rails (2), pull the 8mm nut holding it down on the valve cover stud. Then, remove the T40 bolt on the side of the cylinder head (somewhat hidden). Finally, lift the line off of the valve cover stud and slightly bend/maneuver/work it away from the valve cover.

[@PlanAman]

Do you have any recommendations for parts like pistons? Mine has a cracked piston diagnosed by looking in the cylinder with a bore scope; I plan to rebuild it but see so many places selling pistons that I assume is low grade parts

[@NiXFiX]

Several Jaguar parts have been made in China for years now. You'd probably be fine with a copied part. Whatever you do, don't put AJUSA head gaskets on your car. Here is an AJ126 piston from a seller I've bought from. I've been super happy with their/his head and valve cover gaskets. www.ebay.com/itm/224872209655?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=VfK7IiyQSdq&sssrc=2349624&ssuid=KRNnsBjXRmW&var=&widget_ver=artemis&media=COPY

[@PlanAman]

Thanks that’s the site I was looking at

[@CezarianBass]

Nix i followed the steps and have the maintenance manual for some reason mine will not fire up do you mind assisting

[@NiXFiX]

Did you get it? Sometimes they take a really long time to fire up after the fuel system is opened up. Try pressing the accelerator pedal while the engine is cranking. Did you make sure the fuel pump timing chain was timed correctly?

[@ananonymoususer7693]

15:06 is it necessary to take off the valve cover and coil packs and injectors to be able to take off this timing chain cover alone?

[@NiXFiX]

No. You can take it off without removing the valve cover.

[@ananonymoususer7693]

@@NiXFiX I really appreciate you for your quick reply :) I just need to reseal that cover on mine and knowing this should save me a lot of time, thank you.

[@NiXFiX]

@@ananonymoususer7693 just be careful to not hurt the valve cover gasket while taking it off and not displacing it while putting it back on.
