Hi
I went yesterday to change oil on my LR3 and LR dealer recommended 44K fuel treatment ,car have 67 K mile (05 HSE). Now every time when is engine cold I hearing valve taping more then before,do 44K cleaner cosign valve noise and is that normal.
Do I need to be concern .
Thanks

 

no something else may be the problem?

that takes a while to get thru the fuel tank. are you sure its not a squeaking from a belt. if you still have a problem. take it back to see whats going on. they will look at it for free.

 

Thanks for replay
After treatment I did approximately 20 mile before I start hearing noise only when engine cold. I will drive for a week if is noise still there I go back to shop.
