I would pull the trans and check this out before running the car much more.vibrations don't usually go away on their own and can and do lead to other problems down the line....if the vibration is severe enough, it will eventually cause other things to work their way lose and cause more problems...

also, check out the pilot bearing in the end of the crank while you have things apart.....

My guess, is the clutch disc itself may have lost some of it's material and throwing things out of balance, just my hunch.....

Hi David,
I was afraid someone would say that. Tonight I checked the balancer, driveshaft, engine mounts and tranny mount as well as clearances. Nothing wrong. That seems to leave me with the inevitable. One thing I did find during my search is that I have lost a header bolt on the driver’s side and a few others were loose. I was unable to fire up the engine to see if that had any effect because of the time. I’ll give it a check tomorrow. I have sworn off any new thrashings of the car until I get the problem fixed.



Thanks,

Mike
