what would physically happen for it to come loose? Would I be able to feel any type of wobble or something while pulling on the gear by hand? Would I be able to see grooves or shavings on the edge of the gear near the press surface? Why don't some other press fit items have to be heated before pressed in?
You will not Or most likely not feel any movement by hand. But once the cam is put into a load. This is when it can and WILL move. At this point you can do 1 of 2 things Replace the gear Now. Or if your cam is drilled in the end you can add the bolt and washer to it. In all my cam gear installs I do both I heat the gear and install MY bolt & washer. Nothing like what PES used to sell. And you had this big bump in your timing cover. I have seen some were people would weld a freeze plug to their cover. Hummmmm NOT for me That's just UGLY.
PS AND yes if it walks it will also mess up the CAM AND LIFTERS. If it walks far enough. The lifters can mess up the cam lobes.
