What color is the oil? When my compressor died, it spit oil all over my engine bay. I thought it was engine oil until I relized it had absolutely no black in it; it was the a/c oil. Had to replace the compressor + accumulator + oriface tube.

Could also be something to do with the harmonic balancer pulley, but that's for someone else to answer.

Just by symptoms and mileage, I would say the harmonic damper on the crankshaft.

Your damper is MOST LIKELY walking forward and your crank bolt is most likely also loose! Better get this checked out SOON before it damages a LOT of other stuff! The damper is a press fit (at least is suppose to be) on the crank snout so the crow bar test method may NOT provide you the info that you need to see if theres a problem!!

How much clearance is there from the front of the timing chain cover to the backside lip on the pulley!?!

Measure that and post the measurement!
