Please help with Rattle coming from cam cover?
Doing the oil on my girls 08 5spd and noticed a rattle coming from the engine bay while parked at idle in neutral. It comes an goes, nothing constant about it. Best guess is its coming from the cam cover and sounds kind of like a pot of boiling water with a lid on it kind of rattle (best I can describe) doesn’t sound like a lifter, or a lower bearing, but I’m not up on my Toyota tech. any ideas that can point me in the right direction?

Could be the heat shield between the exhaust manifold and the firewall. Or, it's just our normal valve tapping.

got around to taking a closer look today. Pulled the accessory belt off and the noise went away. Put it back on and it was back. Pulled out a stethoscope and tried to listen for anything out of the ordinary on the a/c, alt and water pump. Think I can hear the noise coming from the water pump. Every thing else sounded normal, but I can hear the rattle when I put the scope on the water pump near the pulley just not as loud. Any ideas?

how about a faulty Timing chain tensioner? would having the belt on cause extra strain on the chain causing it to rattle? i would think the noise would get worse when you loaded the rpms if it was in the timing gear set?

With the belt off grab the wp pulley and try to move it side to side. If it moves theres the trouble. Shake the alt and ac pullys too.

This is clearly not a chain. Sound like a faulty bearing.
