1G Bad vibrations

[greekgodchaos]

My buddies talon has a rebuilt head, stock everything else, balance shafts in and aligned right, crank pulley is fine, just did a clutch job, and new fluids in everything.

At the moment, it idles smooth, but when you accelerate 2500+ the whole front of the car starts vibrating and shaking really bad, if coasting there is no shaking. no leaking CV boots, no leaking fluids, the drivers side motor mount was shot so there is a drilled prothane temporarily in there, we are going to check the transmission mount later today, which is what i think may be the culprit, but i would love to hear input from others as well.

There is also a noise coming from the timing belt side, which we think is a bad bearing one of the pulleys but won't be able to get to it till next week, thoughts?

Oil sprocket might not be in phase it causes vibration like ur saying after around 2500 Rpm

Loose motor mount. Check em, check timing, balance shaft, belt.
