The vibration isn't dramatic but it very noticable at certain RPM's. I had taken the car out for a drive after putting in new trans, rear, and clutch. All revs were smooth and i went to break in the clutch. After realizing the oil was shooting out from not having replaced the dipstick (along with a momentary touch of the rev limiter), I replaced it and there is a vibration at 2k and 4k. What did idiot do to his motor? Appreciate input on what to check...thanks. Motor has 15k.

 

anyone?

 

Did you have the new flywheel/clutch match balanced to match the old setup?

 

yes the clutch was zero balanced and seemed to work fine. The vibration appeared after a 1 hour test drive
