Just a quick question, trying to remove the pulley (Non Turbo Z) and i noticed some small chunks missing from the edge of the pulley (the lip closest to the timing belt). Would this affect engine wear at all due to a somewhat 'unbalanced' rotating mass?? or is a gram out of a few kilo's irrelevant in this situation?? They've obviously been there for some time and I haven't noticed and never found any metal traces at oil changes.
I wouldn't be too concerned, probably caused by someone trying to get the damper off without a puller.
there are some cheap pully's here. why not replace it to be sure. http://www.aus300zx.com/forum/showthread.php?t=309178
