Congratulations !

NO ! The crankshaft pulley should show NO signs of vibration.
This had best be looked into before it gets a lot more expensive.

Main point with the valve cover vent repair is cleanliness.
Clear away the old RTV, then do it again, then again until you see NO signs of the old material.
Plastic scrapers, brass / copper brushes etc, then clean real good with alcohol.
BE CAREFUL WITH THE SCREWS, THEY ARE ALUMINUM !
