Welcome to JustAnswer Mechanical Support!
I amCustomerand I will be Investigating and Supporting your question today.
I understand it can be really frustrating when your auto is not working an expected but don't worry as I am here to help!
I may need further information, however, if required I will let you know!
Sorry to hear your having issues with your vehicle I will try to assist you.
Have you replaced the timing belt tensioner and the idler pulley as well ?
When does the noise appear when idling with car stationary or driving ?
Check the oil level make sure it is correct level.
It could be one of those items I have mentioned above or could be a sticking camshaft lifter or [water pump](/topics-water-pump-toyota/) or at worst case the crank shaft big end bearing.

My oil was just changed last week so the levels are good. Yes the tensioner and pulley were also replaced. The rattle only happens when I'm stopped at a light with my car in drive or when it's parked but running. Once it's moving it doesn't make a noise

Is the noise 100% from the [engine](/topics-engine-toyota/) as worn clutch plate springs can cause this noise and will go away whilst driving it.

Possibly the water pump bearing, [alternator](/topics-alternator-toyota/) bearing or sticking hydraulic lifter.

Is there anyway for you to narrow it down or should I take it to an in person mechanic

You can use a long screwdriver like a stethoscope to check the bearings on the alternator and water pump if they are accesable.
Still not sure what you need?
Have a certified mobile mechanic diagnose what's wrong with your car, at your home or office.
