Hi!

i just got the supercharger „Torsion Isolator„ Replaced on my 2010 xkr 5.0 because it made a extremely loud noise. Today i heared a slight engine rattle. Its barely noticeable when the hood is closed but im pretty sure that it wasnt there before. I cant tell tho because the Supercharger noise was getting extreme.

Does anybody have a video of how the engine should sound like normally? It would be much appreciated.

The car runs 100% fine (even better then before) but this sound makes me paranoid


EDIT : here is the video on youtube (its not a normal video its a short i don‘t know why i cant change it on the phone)

My original isolator must have been in good nick at 70,000 miles, as I had it replaced and the engine sounds identical.
Can YOU take a video of your sounds and post it on somewhere like Youtube, then link it to here?

 

I will take a video today or tomorrow

I have another question tho. I wanted to change the Oil of the supercharger. I called the nearest Jaguar shop & asked about the oil and they said that this Supercharger uses no Oil which makes absolute no sense to me.

 

Yeah, find a new shop. There is a Sticky on the top of the X150 page labelled Maintenance, where you'll find this link:

The 5.0 is a bit tricky to accomplish, but very doable.

 

Yeah i think they wanted me to buy a new SC or rip me off i don‘t know what their plan was😅

The link for the video of the rattle is above

 

The 5 & 3 litre engines are quite noisy as compared to almost any other engine. If the main dealer told you no oil and wanted to sell you a new assembly, they were correct as main dealers do not service superchargers, they only replace new complete assemblies which are supplied prefilled with oil.

 

No need to worry about that sound it is perfectly normal for the AJ133 (V8) and AJ126 (V6).
They are both GDI - gasoline direct injection - with very high fuel pressure and for that reason both the fuel injectors and high pressure fuel pumps are quite noisy/rattly.
At most one or both of your high pressure fuel pumps (there are two of them low down on the right side of the engine block) are starting to rattle a little more than normal, this is known to happen on some high-mileage engines.

 

Thats a relief! Thank you very much.
I thought it will get expensive again 😅
