I'm in the process of putting a new block in and after pulling the old one, the UDP is stuck to the lower timing gear. I'm thinking a bath in a small vat of PB Blaster will do the trick...and for the Harmonic Balancer bearing stay bolt...it seems as though the impact screwdriver and more PB is about the only way to get that rusted piece of junk out...any thoughts?
