I have just purchased a corolla with a blacktop 20 valve 4wd , not knowing too much about them I would like to know if anyone might know what might cause a noise I have from I think the engine. It does not sound like a bearing noise more like a growling whirring noise increases with engine revs. It's a little bit hard to explain exactly kind of sound.

Ahhh, you mean that funny noise, yeah i know the one. don't know what it is though.

What model corolla have you got? I am asuming someone has done the 20 valve conversion? If you think its the donk poke your head under the bonnet and give it a rev? If you want help, go into a bit more detail dude, or maybe throw up a vid if you can.

Unless you're better with words than Shakespeare, you haven't a hope of getting us to imagine the noise you're hearing.

 

The only answer is-

throw up a vid if you can.

 

Is it a Tercel? with its three whiny diffs??

I had wondered an AE95 perhaps. Id like to see it either way :yes:

vid of noise

it might help if you post your location, then someone local could assist. I'm in Ipswich Qld, and will happily look/listen for free. i fix this stuff all day long

Have a rattle?

 

Sounds like the common 20v vvt solenoid.

yep, very common problem. sounds likely it will be this.

a strange growling noise that increases with revs? coming from the engine?

 

probably the quad throttle bodies doing what they do best...
