Post subject:  vibration

Continuing on this older thread, I do have poly motor and tranny mounts. The thing is, I had my vibration before I switched over from rubber. I'm wondering if I solved one vibration and started another. Still, the vibration seems the same before and after the rebuild, and it was rubber mounts before and poly after. Looking into other sources still, can't find any vacuum leaks, doesn't seem to be from the exhaust system. Motor seems pretty smooth, doesn't seem like a misfire.

Did anyone happen to have such a vibration issue and notice if their timing mark was steady or not? Mine is jumpy, both before and after the rebuild. Still thinking it's the torque converter or flex plate. Will get to those.

Thanks for any insights.

Brian
