When accelerating, There is a ratling loise coming from the engine bay somewhere and i cant seem to pin point the exact location.

I thought it could be the belts maybe? or the pulleys?

I videoed a short clip of the engine running at idle but my post count is too low to post a youtube link

What do you guys think?

If it's the original belt tensioner.. I would recommend to replace it. Tapping noise is the fuel injectors.

it most likely is the original tensioner, second owner with 80,000kms on the clock

in the video, should the tensioner be moving back and forward like that?

hopefully not fuel injectors, it does seem to lag sometimes like it hasnt got gas but that doesnt happen often

Here is another video showing the noise better.

It happens when in drive or reverse only.

Sounds like your belt is squealing. A worn belt can also cause a rattle on acceleration. Seen it many times on older Toyota Corolla 1ZZ-FE engines. Wasn't the tensioner, just worn belt. Not saying you shouldn't check the tensioner operation, but sounds like you need a belt between the rattle complaint and the squeaking I hear.

Injectors are always noisy … normal operation

Okay great.

Anything else it could be other than bad belts?

tensioner is the easiest & under $100 Diy
