It's not a pulley, tensioner, or belt...checked and triple checked. It makes the sound w/no belt on it.

It's loudest on start up and after I run it hard. Over a few minutes it quiets down but is still there, just at a quieter sound level.

It sounds like it's coming from under the passenger side head/intake manifold

 

check your rocker arms and pushrods

 

What he said ^^^ and might want to drain your oil and see if there is metal in it and also if its smells burnt.

 

Pushrods are fine, and rockers are fine.

 

Could it be a lifter or maybe even transmission related? I have an auto w/stall

 

Not your transmission....

 

lifter........

 

did you just recently put the stall in the tranny?? Cause not all aftermarket stalls will just bolt in. sometimes you have to put spacers between the bolt and the flywheel, cause the bolt holes on the stall isnt deep enough for the stock bolts. which makes ur stall rattle.

 

sounds like more than one lifter

 

I thought a bad lifter would make more of a tick sound, not a squeak/chirp

 

Gonna buy a stethescope and see if I can get more specific on the location.

 

Take your assceory belt and start the car could be pullies. Any codes or mis fires?

 

tried it already, it still makes the sound w/no belts on it
No codes, haven't logged it for misfires though.

 

My car made that noise for a few days... then a lifter gave out.
