cam bearing issue

After you install the new cam, put the timing gear on and see if you can then turn it by hand. If you can, you will probably be ok.

If you try to machine the cam bearing hole, you may make it oversize and then the bearing will not have a tight enough fit and eventually spin on you.

Unfortunately, Chrysler has been known to let "out of tolerance" parts get out when they get in a pinch... Very sad.
