Hey what's up guys. So just an update, I received the Dr. Vanos rebuilt vanos in the mail today. I inspected it to find that he basically drills two new holes in the vanos where the exhaust hub tabs go into. It appears that the newly drilled holes are slightly smaller than the factory holes, fitting the tabs tighter, which is great news! I test fitted the hub, and there is a bit of play in the factory holes (one of the factory holes is damaged, but the other isn't and there is still a little bit of play in the undamaged hole). Then I test fitted it into the new holes and it fits tight with no play. I hope this solves the noise problem and prevents the tabs from potentially breaking. Now I'm just waiting on the upgraded cam bolts because they were not included in this shipment.
