Slipping vibration damper seems more feasible.
If it is the bolt loose, you've been fuckin' lucky!
the supra had the front bolt loose when it failed but it also only had 20 psi of oil pressure due to a majorly failed conrod lol.
I will know more Monday once the rads out and I get my head in there, ive been looking and I can get a fluiddamper if it is just the rubber failed on the stock damper.
the engine runs perfect I wouldn't have known except it stopped charging and I felt a slight vibration from the gearbox.
