Strange Metallic Whirring Noise

RustyRatRod said

Are you talking about that REALLY high pitched sound? More like a squeak? That's metal on metal. It'll turn up sooner or later. lol

I have heard throw out bearings and pilot bushings do that if they were dry, but usually, you can tell a difference when you depress the clutch pedal.

Yep, the squeak is it, not the rattle. Comes and goes oddly. Sounds like a bearing, but just have a hard time believing it's in the main bearings..Maybe the thrust bearing. Just hasn't gotten much worse over the past 6 months. And no, can't really tell a difference when the clutch is in. Seems as if the thrust bearing could be wormore, but not enough to see any movement when watching the crank pulley while revving the engine. Might take a pry bar to it.

Just keeping it running for a 6 or so months until I build up another motor is my goal.
