Rb20det Spinning/rotating Noise From Front Of Engine

[rayj]

Hey

Just want to get some opinions.

It's hard to explain a noise, but I think the best way to describe it is - it has a spinning sound to it. It's not a rattle, squeak or screech.

It comes from the front of the engine area. It's not belts slipping.

It's usually always audible, but tends to go away at a higher rev range, around 2500-3000 revs...

Cheers

Probably the timing belt cover has been bent during a belt change.

Narrow down the noise source.

idler pulley, gates belt?

[rayj]

It's not the timing belt cover, there's no bends in it.

It just started randomly and obviously got me a bit worried it might have something to do with engine internals...

[GH05T]

doe it get worse when warmer?

[rayj]

Nah, it always sounds the same, and goes away at the same point in the rev range, above 2500-3000. But as soon as revs drop below that rev range the noise comes back

still running a clutch fan?

[tridentt150v]

Turn off your a/c and see if it still happens? Could be that, fan clutch, alternator or water pump. But you can almost eliminate a/c if you turn off your a/c and it still happens.

Over tensioned timing belt

[rayj]

It's not the AC because it still happens when it's off or on.

What's a good way to check? Could I spray some WD40 around at specific things to see if it goes away momentarily?

[GH05T]

dont do that.

take it to a mechanic, fix the over tensioned timing belt when they tell you that's what it is.

Hey did you get to the bottom of this? I’m having the same problem rn
