hey folks not sure if this is in the right section

for the last couple of days when i accelerate theres a high pitched noise kind of a buzz coming from the engine, the more revs the higher the buzz, im not the most talented when it comes to engines but checked all the belts thereall fine its more of a motorised buzz, any ideas would be helpfull, cheers guys:) ?

low revs it is a sort of buzzing motor noise, as i accelerate it just keeps going higher

towards the top or bottom of the engine??? I'd say it's the lifters... could be anything without more info though....

Idler pully for the aircon or power steering belt.

When was the last time the timing belt was changed? Could be the timing belt tensioner or idler as well.

Be careful about driving it until you figure it out....you dont want this to happen

Had a better look at it 2day, turns out it was the bearings on the air con pulley, but noticed all the other belts are on the way out, so they will need replaced lol
