Tony, on the antique stovebolt engines most of the guys here are dealing with, that might be OK, but I've got a bunch of worn-out cams with very short running time that makes me tend to disagree with your method. Also, the low-tension rings that have been used for at least 20 years don't need the pressure of driving to aid seating. The last time I heard of the "drive it and load it" method of seating rings was about 25 years ago, in a Perfect Circle seminar I attended. Times and machining methods have changed, and our methods need to change with them. Once we get set in our ways, and quit learning, we're likely to dismiss any new information that's available. Check out the wear limits on some of the new engines, with piston skirt clearances of .0005", and 5W-30 oil! What was once a normal buildup clearance on a new engine is now "worn out".
