Close on 2 years ownership of my 5.0 S/C

Always intended on "visiting" the camchain tensioner and guides (96,000mile)

Well after a 70p O ring caused a £600 worth of parts water leak I thought “while I am here I suppose now is the time” - coolant leak was from alloy pipe O ring behind oil filter housing

Camchain assembly now held together with zip ties till I get new tensioners

Guides are in great condition and like the tensioners are the later style

Old tensioners are very weak and not much life left in them - they didn’t even spring out when I released them !

Oh and Range Rover say “it can’t be done with zip ties”

Well we will soon see once I eventually start it up

What’s the worse that can happen - lol lol

The person who stated that obviously didn't get the memo. There is a published Jaguar Land Rover procedure using zip ties to secure the chains while replacing guides and tensioners. Its a bit different to what you have done but it uses zip ties (called tie straps in the manual).

Any part No Guru’s on here ??

My part number cast into the tensioners is

FX23 6K254 AA

I understand how Ford/JLR usually identify updated parts by the last letter

My question is a FX23 6K264 AB the latest spec tensioner ?

Also known as LR095472

Have you seen the AB suffix on any tensioners?

The last tensioners I replaced were around 6 months ago, purchased from the dealer - they had the AA suffix and I have not heard of any newer revisions.

Yes AB is the tensioners I am looking at

What a most satisfying sound !!

Pull the pin and CLICK out shot the plunger

Old tensioner is on bench and will not extend as it stuck in now after I “reset” it - lol

Let the rebuilding begin tomorrow

When I was doing mine, someone in America who has a lot of experience rebuilding these told me to use a big screwdriver and gently lift the guide off the tensioner until you hear another click or two. He says he’s seen them skip a tooth when starting if you don’t.

There’s no mention of it in the manual so make of it what you will

I did it on mine and haven’t had any issues in 6000 miles.

The tensioners that I bought from Duckworth’s in September last year were the AB version too.

2nd tensioner replaced

The old tensioner had a lot more tension then the other one

New crank seal fitted and crank pulley back on

Just need to torque crank bolt without moving crank anti-clockwise at all

Good job I know a mate with a laser cutter

Made me some blanking plates

Symposer delete before Supercharger goes back on

Did an oil change and coupler replace also on the S/C

All going back together nicely - may even go for an engine start soon 😱 💥

That’s interesting…

My 2012 doesn’t have a symposer. I read somewhere that only the Sports had it so interesting that your car is fitted with it.

Not sure why fitted to mine but certainly looked “factory”

Here is a pic of vac pipe Y piece going across engine to actuator on symposer

Thankfully it is no more
