strange sound from engine

[Vertigo]

im getting a rather strange rubbing/whining sound from the engine (2A) at or above 3500 rpm. it doesnt stop as soon as i let my foot off, but rather eases off until below 3500 rpm agian. any suggestions as to what this could be?

what does it sound like, metal on metal?

one of your exhaust heat shields mabey...

my first guess would be to check the accessory belt(s) are tight enough

I had a similar sound on my old laser. It was the cam belt tensioner. It was cocked off a tiny bit so when the engine revs were high enough the cambelt 'walked' sideways and rubbed the plastic cover.

Mate, it could be any number of things, from a squeaky fanbelt, to a cambelt tensioner. No point waiting for guys on here to guess your problem, take it to a mechanic, and get them to have a look.
