Ok I've had 1 22r and 2 22re's apart now to find bad rod bearings on all of them! WTF? There has to be a root problem here... I noticed there is an oiling port at the base of the rods. When I stuck a drill bit into the hole frome the bearing side I discovered that it necks down right at the end of the port. Can anybody give me a good reason not to drill that out all the way through to maybe help keep those lubed?
