Curious, my b16 in eg makes a whine when revving it. I was thinking the tensioner or timing too tight? It's an oem older tensioner with low km. and new gates timing belt / water pump. It's been like this for a season

 

it could be your clutch release bearing aswell if the noise is coming from near your gearbox or distributor

 

We can't hear it. So it's hard to tell.

I have noticed that B16s do make a mechanical whirring noise. If thats what you're hearing...its normal.

You should have changed that tensioner, BTW.

 

My B16A2 whirs too.

 

Yeahhhh the gates kit should use one. Easy swap I will make a video and prob. New post at some point of the noise! Keep posted. It's def that common b16 sound I also have heard it.

Also read about Jdm motors using two washers on the crank pulley not one. That has me wondering pretty sure my Jdm block is using 1

It's def in the cam / lower cam and timing area I have no cover there right now. It's loud! But I race the car hard it's turboed so nothing really harming things ..yet
