The stats: Rebuilt motor dropped into car with aluminum flywheel & new stage 3 clutch. 600 KM on the car now.
When starting up from stop in first gear and moving in reverse, there is a pulse, shudder or chatter on engagement. Also when in neutral with the clutch pedal pressed I can feel a pulse through the pedal.
It is RPM related. At 100KM/hr the vibration is not bad, rpm under 3000. At 140KM/hr the car feels like it is coming apart, 3400 rpm?
I do have a leak from the back of the tranny coming from the output shaft. Would that leak if there was too much oil in the tranny? Or have I lost a seal?
This shudder was in the car before I changed the engine but only at very high speeds. 180KM/hr+. I assumed the wheel was out of balance.
My thoughts:
Bad clutch/flywheel?
Propeller shaft of balance?
Wheel off balance?
Warped output shaft?
Toss match in gas tank, walk away?
Any thoughts on this will be well received, thanks.
