my 87 TD is beginning to exibit 617 sounds

I absolutely LOVE my 87wagon. however, this morning after starting the car, and beginning to drive out of the apartment complex, I noticed a pinging rattle just off idle... when I payed CLOSE attention to it, I noted it at idle and slightly above idle driving around.
now, when I say pinging, I mean a SLIGHT warble just noticeable above the amazing smooth quiet murmur of the motor.
what say you experts?

air?
injector hammer?
I'm crazy?

It might be the belt tensioner damper starting to lose its end bushings.
