Pincourt,

Fidenza lightweight
BS removed.
Just did an engine cleanup on my 6 bolt on my 95gsx. Took the engine out. Cleaned her all up real nice, paineed it. Cleaned the timing components (oil spill) and re timed everything perfectly (except oil sprocket). Engine internals and head were not touched.
I seem to be getting lots of vibration from the crank sprocket ( not the pulley dampener). I took the timing cover off to visual check the belt operation. I can see the belt run true the entire cycle, except for when I look at the crank sprocket. There seems to be a vibration and the sprocket does not look like it spins true (minor but noticeable). I can look at the oil pump sprocket and see it spinning pretty true. But the belt from the oil sprocket to the crank sprocket and crank sprocket to mid way to the eccentric pulley seems to have a little vibrations. As a consequences, the vibrations intensifies/exaggerates when I have the harmonic pulley on, and as another consequence, throws my alt belt (have the GM alt on).
I need to know if I'm being paranoid or this is normal crank sprocket vibrations (torsional whip??). Its driving me nuts.
