20v Timing Belt whine started 3000k after i changed it WTF?!

[dtour]

Car - AE86

motor - 20v Silvertop

use - its says personal on the rego?

problem - Timing belt whine

occurs/started when - 3000km after i changed it

personal situation - boored, broke and confused

So i replaced my timing belt before i installed my new motor in March, over the past couple of days the timing belt has started to whine. Its a genuine toyota belt too and I dont think timing belts magically tighten themselves.

Has anyone seen or heard of this happening before?

[Sam-Q]

the tension isn't too much?

sorry it's all I can suggest

[biggo]

pull the covers off tho and check its not rubbing on them.

[dtour]

i am pretty sure that the tension has increased, i took the cover off this afternoon and the belt isnt rubbing on anything so i am going to take the lower cover off 2moro arvo and check the areas i couldnt see

im so confused :|

id would just reset the tension and see how it goes.

cars do funny things sometimes.

Maybe you need a belt tensioner bearing now also. It is common for a mechanic to replace the timing belt pulley/bearing/tensioner when a new timing belt is put on. Mostly just to save time down the track, as its harder to get to on a FWD.

Make sure you have a silvertop belt and not one for a blacktop.

When I put my Toda gears on, there was a bit of black T-belt dust for a while untill the belt settled into the new gears (which obviously are cut very slightly different to the stock ones.)

Hey jonny, yeah i replaced the tensioner at the same time.

I did fix the issue however.
The belt was just a little tight. F*^ked if i know how that happens but watever its fixed now.

its weird but ive seen it happen before aswell at work, had a couple 323's come back after a couple thousand k's and the timing belt is whining off its head. just retension and its all sweet.
