The car has a loud clicky rattling in front of the engine we used to be able to spray wd40 and it would stop but now it does not.

Hi,

What did you spray the WD40 onto? If it is a rattling sound, it could be a few different things such as a catalytic converter, belt tensioner, or belt-driven accessory.

Is it possible for you to record it making the noise and upload it for me to hear?

Let me know.

Take care,

Joe
