Hey how's the vibrations from poly mounts with no balance shaft ? Do you lose fillings ?
There is a way...you have to get everything to sit on the poly mounts equally..
A procedure of running with some of the mounts lose for a couple of days then tightening .
Loosen other mounts ,,drive then tighten ..repeat
I actually did them one at time over several weeks...
I get no vibration at idle...slight vibration at 2300 rpm disappearing almost immediately by 2400rpm .
I believe Lowell has a similar procedure for reducing vibration..
