Okay so I just rebuilt my whole engine. Was checking the crank and it had a tiny amount of up and down play on the drive gear side. If you grab the drive gear and wiggle it up and down there is a TINY but of play. I mean like so tiny its about the width of a human hair. In fact the only way you can really notice it is if you shine a bright light at the crank seal and look at the grease on it to see the light on it change. You cannot physically FEEL anything. I'll be very clear in stating that both crank bearings are brand new, never used. I am hoping this is not a problem and its normal. Am I right?
