Vibration in engine- help!

I'm goin for somethin in the bellhousin comin apart. you've got a vibritaion. That would explain that. Your clutch pedal is acting differently. That would explain that. I think the sputterin and missin was a totally separate issue. Don't worry about a spun bearing. You said the oil was clean. No worries there. I bet somethin in the clutch disk pr pressure plate is fixin to sling apart and tear some stuff up.
