XFR Engine noise
#21
Jagwower is right, the engine blocks are not at all the same, although both use mostly FoMoCo bolt on parts, and both were originally (but separately) designed by Ford (in different divisions on different continents). In addition, both are NOT made by Ford. The AJ133 is built in a specialized Jaguar factory by Jaguar employees in a UK factory which is indeed next door to a Ford of Europe engine factory. The Coyote engine is Canadian made. Incidentally the article quoted by the OP is wrong on several counts, the Voodoo engine is the same as the Coyote except slightly bored and stroked to add 200cc of displacement. I am not at all aware of any particular large scale problem with timing in the Jaguar engines during this period. The AJ133 does not appear to have this problem to any greater degree than other modern DOHC engines.

You need to check Range Rover for this period.
All over the place in that forum.
You can say different factories, but truth be told they share parts all over. You are splitting hairs.... my point is there is a problem. It could be a coincidence that the same years as Ford and jag/ Rover have problems. My guess is shared tensioners and possibly guides.
I would advise an oil change from the pan, so you can check for particles. I've done mine through the top via vacuum and it really doesn't allow you to check the oil.

Not splitting hairs. Just trying to provide correct information for people who use these forums to find correct answers, not misinformation.
I'm not disputing that there are or are not issues with both engines timing chains/tensioners/guides or whatever. Just that the Coyote and the AJ-V8 aren't the same.
That being said. Did you get the service done? Are you doing it yourself? What was the cost? Was there any additional damage to your engine?

Dealer wanted $6k-$7k and indi wants $3.5k ...No damage... no codes thrown. The big money changer is if there are codes thrown and engine is retarding. That means the VVT has to be replaced. Dealer replaces vvt regardless to avoid redo, but indi said if there aren't any codes and it's running fine prior they are still good.
I cannot tell you the last time I paid for service on my cars. But But the indi said it's easily a 2 day job. Too much to take off to get to the timing chains/tensioners/guides. Those challenging little bolts on the firewall side geez!
Honestly... it looks easier to do with the engine out. I figure it's the perfect time to replace supercharger snout and pump while it's torn apart. That should account for a $1k savings on labor for future service.

New update... the indi said my noise does not sound like the timing chain, as it's usually a lot louder. He said it could be something else, and he said drive it until it gets a code. I'm not liking that logic, but I have been driving it for 3 months with this sound. The indi said I could pay him and end up with the exact same noise... then what. There is a thread on here where the dealer replaced it and they had the same noise, and another dealer did it 3 times before the noise went away.
He did let me listen to an XKR and it had a lot of noise with a random tick noise near the rear and the same clunk noise when the motor turned off. The indi said these are loud engines with 2 direct injections pumps pushing over 1500 psi.
I found a thread that mentions issues with the 5.0 SC motors blowing and most likely due to starvation when cornering hard or hard acceleration. The lowest my oil was 1.5 qts low, so I still had about 6 qts in there. Which is weird since I change my oil every 5k and the max was 7k miles.

This noise , but it isn't the supercharger or water pump. I removed both belts and it was still there. I do not have any lights or pending codes.

Jag dealer said timing gear , and independent said wait for codes. He said these are loud motors.
It does go away at 1250 rpm.

it was timining chain, vvt, and tensioner
He came back and said the passenger side had a lot of slack in it. One of the VVT's was bad and the chain had a lot of slack.
He wasn't sure what caused what, but due to the chain slapping around all parts needed to be replaced.

Is the car under warranty? CPO vehicles are warranted to 100,000 miles. If so, take it to a dealer. You could have a "stretched chain" that has not set a code, but will show up on the dealer scan tool.
My XF, at 70,000 miles developed a "stretched chain," The dealer replaced the chains, tensioners, water pump, a whole bunch of other parts, and even changed the oil. They told me if it was not under warranty, it would have run about 6K. It cost me nothing, and they even gave me a loaner while the work was done.

You crack me up you've got professional advice, then you went ahead and start to mislead other readers that the AJ 5.0 engines are the same as ford coyotes and now we're back to.... You needing chains, tensioner, and isolater.

Read up ... the fords of similar years have vvt issues and it also tend to be on the passenger side. I honestly think it has something to do with oil flow to the vvt and weak parts parts.
So you tell me... is it just a coincidence or a shitaki load in common.
