Hello All

I went away for about 5 days, my CAT doesn't get heavy use either, but when I came back and turned the car, I noticed a considerably loud slippping/rubbing noise coming from the Jag. It was loud during idle whilst i was in park.

More prominent towards right side maybe near the wheel
Sounded to me like a belt but i dont know.

Car did take slightly longer to turn aswell.

The sound gets faster as I accelerate and slows down when Im idle.

The sound gets louder if I stick it in neutral, yet when I put it in reverse or drive, it goes back to its normal loud sound.

It is loud enough that i can hear it with the windows closed.

The sound is very prominent from the drivers side of the car.

I will try to take a recording as it is difficult to describe the sound. It is rather fast, like every half second whilst in idle. As RPM increases, the sound of the rubbing/clicking is drowned by the noise of the engine.

It is not a rattle
It is not squeeky

Model : Super v8 1998
Mileage : 105000
Oil : Looks like it hasn't been used since its last service in March. Clean.
Temps : Temp gauge reaches middle and is fine.
How was the car before this issue? Perfectly fine.

I start the car whilst pressing the accelerator, then keep it pressed to about 1.5 revs for a few seconds and let the car settle. The reason i do this is that otherwise the car starts then cuts itself off. The last time this happened i was lucky as it was at the garage so they had to take the plugs out and clean out the oil. Then once plugs were put back in, it was fine. But they told me to always start with the accelerator. Luckily it was them that flooded it!

CURRENT BEST WAY TO DESCRIBE NOISE :

Play this clip
Put the speed to "2"
Now you hear that noise at that speed? Well its that but without the girly "hah" sound. If you try it yourself now, at that speed, try to breathe out like that, well that's the noise i hear from my car.

 

Have you renewed the tensioners?

 

The serpentine and SC tensioner and idler bearings are what bcrary3 is referring to, I think. They are likely culprits, but so are the water pump, alternator and SC.

 

I would sure not drive this car until I had it sorted out in case it is the tensioners. Catastophic engine failure is quite possible if that is what it is. Just have a look at the archives for tensioner failure!

 

Suggest taking a video of the noise, uploading it to youtube, and posting the link here. Much better than describing the noise!
