It is probably the cam position sensor and synchro. It may sound like its coming from the belt side, but it isn't. If thats what it sounds like then that's probably what it is.

Don't just throw your money at a part without definitively ruling out something on the serp loop. A misaligned pully can (and has) caused a chirping sound.

We need the OP to report back if he sees anything out of alignment first before telling him his cam synchro is dead, without ever seeing any actual proof of it.

We're in the business of fixing things, not throwing parts and money at them.

I would take the belt off and start it to see if the noise goes away. Just don't run it too long due to possible overheating.

Removing belt, and then having sound removed won't narrow it down to the belt. It just narrows it down to internal parts of the engine etc not being the problem

You replaced quite a bit of parts, except the tensioner pulley. So, here is something to do so you don't go on buying parts.

This is what i did to narrow down if it was the tensioner: Started the engine, put the breaker bar on my tensioner bolt and then started turning it clockwise or maybe counter, anyway the way which have added pressure to the tensioner.

The noise went away, thus I had a bad tensioner. Replaced it and noise gone. Hope it helps
