Yes new OEM flex plate and torque converter and mounts and water pump and idler pulley. It vibrates at any RPM even if you idle it up in park
3000 RPM you think the glass would shatter out of this thing, I, v driven the, s cars at the shop and they doin, t do this and they have 200,000 miles on them and you cant even fill them running. Guy, s I, m a 35 year auto teck and transmission builder and just cant seem to figure this one out, you can lay a cup of coffee on the hood and at 3000RPM it looks like its boiling tell it falls off, Thanks for your replys

Yes end play 0.0043 first check cold 0.0038 hot , If you wont to feel the vibration take an old grinding wheel and knock off a chunk and put it on your shop grinder-wire wheel and hold on tight, its deafening and that's wot it feels and sounds like, you cant even hear the radio, the car body
is like a tuning fork .
Hope this helps,
Thanks so much saturntech9
My sun drives this thing every day and it has no oil leaks or PS leaks or Coolant leaks, every thing is dry as a bone.
Burns no oil and has about 178 psi to 180 psi compression 1-2-3-4.
Do I need To junk this car?
Thanks Tim

I got a 98 saturn sc2 vibrates bad, the inside outside of car vibrates, worse when first running, clutch is out got it apart putting clutch in today. All the mounts look good, I pryed and tried moving them around checked to see any rubber missing or cracked ect. All seem good. My brother said could be in the clutch system or the flywheel? Otherwise motor somehow out of balance?

I have never really seen the S MODEL out of balance like that. Have seen torque convertors. But not the engine itself. Maybe the crank is some how out of balance.
