Growl type noise at around 3000rpm

Hey guys,

 

Excuse the title but its the only way i can think to describe the noise my car is making

 

Firstly its a jap spec na auto 93 model.

 

Basically if the car is revved up to about 3000rpm + and not under load, it gives a fairly loud vibration/growl type noise. It sounds like its from the top of the engine/inlet plenum...

 

The noise was there before the belts were changed and is still there now.

 

It is absolutely fine to drive, no warning lights etc. if you put your foot down and keep it there, its fine. If you do it and lift off its there..

 

Any thoughts?

check your viscous coupling for play , towards radiator/engine,that makes a noise like that :)

 

I had something similar develop within a viscous fan on an old Capri special I owned. Removed it and ran some engine oil into the casing and it sorted it, free moving and silent for years afterwards. Anyone trying this fix though need to be aware that for older couplings the grease will be thinned by any oil fed in so you don't want to slop in lots.

 

Or it could be the water pump bearing?
