corolla sportivo engine rattles

[Licky]

Ok, I have searched, and i have narrowed one of them time to one of the tensioner pulleys?

One happens at low low rpm, if i take off and give it no more then say 1200 revs, i get a deep rattling noise.

The other one seems to happen at higher revs (between 1.5k to 3k), sounds fairly tinny, will rattle when the car is on the spot as well.

Any help as they are frustrating the hell out of me, its hard to diagnose where they are because of the exhaust is too damn loud.

thanks

If you have a cold air intake. that might be the problem..not stable enough. had this problem. few weeks ago.

hmm, for which rattle? :P

don't know if this might help but i had an engine rattle at high rpm found out it was one of my engine mounts that needed replacing

Could be a list of possible issues, you need to narrow down what is causing it. The low rpm rattle is likely the belt tensioner. Is it rattling just off of idle?

Does the high rpm noise change dependent on engine speed are car speed?

The first one i mention, when i take off wont make any rattles when just revving, will only make the sound on take off. sounds like a stall sort of rattle

The second one i should have said happens at higher revs, usually between 1.5 - 3k, will rattle when revving.

No noises I can ever hear over 3k

thanks,

Mine makes a noise worse when cold

It hums

Like humhumhumhumhum and changes with rpm, might take the belt off and see if it's there..

I need it 100% for a 41hr drive haha
