Torsion damper crankshaft broke...

[Gerard van Santen]

I don't remember that my 91 had this type of pulley on it. I always inspect parts when I take off, but sure don't remember seeing any rubber on the back side of the pulley. It has been a year though. I'm sure that someone out there knows. This may only be a problem for the 3.2 engines. Says something for the old original design, hard to beat.

All NSX's have this torsion damper inside the pulley.

I replaced my pully right after I read this post as a preventive measure... peace of mind
