My car makes this noise, and it isn't the injectors. I can hear it more on the left side(facing the motor).


I used my auto stethoscope and the coupler isn't making noise or the water pump . I can hear it the best when I put it up on the oil filter cap/ housing.

The noise gets faint or goes away at higher RPMS.

This isn't my video, but that's the noise I'm hearing. Thoughts?? 2013 w/ 33k miles, and oil changed every 5k miles. The oil filter doesn't have any metallic bits.

 

It could be the dreaded torsion isolator rattle, search this site for details.

 

I thought about that, but couldn't hear anything when placed the stethoscope on the supercharger.

I may take the belt off, and see if the noise is there without it.

 

That sounds like a rocker or lifter issue as it's very rhythmic. But it could just be normal cam lope. AJ133SC engines are noisy, if as you say you have no metal in the oil, or oil pressure problems I'd just chalk it up to that. You could try a different brand of oil.

 

Hum...My XFR has a bit of that ticking but I also seem to have a little "grinding" of the supercharger upon cold startup and some times hear some rattling on WOT...is this somewhat normal?
Coming from the Merc E63 with 6.2 liter engine with lots of cam noise- All the Merc techs said that it was "somewhat normal." Is this the same case as in the OPs video?

 

I think you may need to service your supercharger. This may be your torsion isolator ...http://jlr.oemdtc.com/76/supercharge...10-2016-jaguar. It's a known problem, but I have zero grinding sound.

As for the video ... just one off YouTube

 

it's not a valve ticking . It sound's like a damaged con rod bearing .
Did you ever run the engine with a low oil level condition ?

Never ... I do all my own maintenance and never had the low oil light come on. I pump out the oil and it usually about 6 qts out.

If it was that... wouldn't it increase with the rpm vs going away? Above 1500rpm it's fine.

Ps. I agree, as I bought a jeep with that issue. But it would increase with the rpms.

 

hope you have extended warranty. sorry to tell you, but that sure sounds like timing chains..
here's another video of a timing chain noise

 

It's all of the above.

I removed some stuff today and narrowed down the sound.

It's one of the upper tensioners, and the supercharger isolator/coupler . Pondering a trade in or fixing it.

No CEL, so it's must be the ratcheting part... bc hydraulics kick in at higher rpm.

 

For the vavetrain issue I honestly would try an oil change first, as in another brand it can't hurt. Valve train noise was a big issue with GM LS-x engines were I came from over at LS1 tech, I switched from Mobile 1 to Pennzoil ultra platinum and my LS1 engine valve train noise quieted down quite a bit. It also helped with a tensioner issue I had with my G35.

 

the 5.0 engines are nothing like the 4.0-4.2 v8's.
5.0 engines don't have upper tensioners. I've done quite a few timing chains.
I'm also sure your s/c isolater is bad also. 90% of the 5.0 s/c timimng chains i've done need s/c isolaters.

 

I removed the supercharger belt and ran the motor without it. The supercharger made noise when spun by hand left to right ... like a slapping sound. However it spun freely to the right or left without any other noises. However , without the supercharger belt the noise was still there. Using an auto stethoscope I could hear it top front valve cover and if I put it on top of the oil filter housing. But but ... it goes away at higher rpms. The water pump sounds fine and shows no signs of leakage.

I do not hear anything from the oil pan.

 

You called it. The supercharger needs a new coupler and I need a new timing chain etc.

I drained the oil from the drain plug and found a bunch of tiny plastic bits. Most tiny specs, but 2 larger pieces.

 

Anyone know the the cost for the coupler replacement at a Indy?

 

Interesting fact! Just like mine... upper left side on a Ford F-150 and mustang 5.0 TSB

Pretty sure that 5.0L Coyote is completely different from the Jag 5.0L, but I could be wrong.

 

There are some intake differences, and the water pump is definitely different, but the core is almost identical.

According to Wikipedia-

The Ford 5.0 "Coyote" is based off of the 4.6L modular motors.
It has a bore and stroke of 92.2mm (3.629 in) and 92.7mm (3.649 in)

The Jaguar 5.0 AJ-V8 III (AJ133) is based off of the other AJ-V8 motors.
It has a bore and stroke of 92.5 mm (3.6 in) and 93.00 mm (3.7 in)

Also the AJ is direct injected, the Coyote is not.

I'm pretty sure they aren't related at all ... but I'm just going off of information I found online, such as yourself.

https://en.wikipedia.org/wiki/Ford_Modular_engine
https://en.wikipedia.org/wiki/Jaguar_AJ-V8_engine

 

Both engines are made by Ford. Both had issues with timing in 2011-2012. Ford is the common denominator.

My 2012 jaguar xfr has ford stamped all over the structure.
