Engine Vibration 3k RPM

Yeah man try and find out what’s wrong before having to pull it out. It really sucks to have an engine in the shop for a problem but there isn’t a smoking gun during tear down.

this is what makes this unique and interesting - it was .030 over when you got it to freshen up. Then it was fucked so you bored it out. Did the previous guy balance his rotating assembly? And is it in your favor or does it actually make the vibration worse!?
