Given a slow revving, low compression engine like a model T, what difference would an extra .005" in the ring gap make. What may be the manifestations of this? In the past I was concerned with too tight clearance but thought little of a bit wider ring gap.

Allan from down under.

Allan, according to the Repco digest of Automotive engine re-conditioning, none, providing the .005" is above the minimum of the .003" per inch of bore and not over the max of .005" per inch of bore.
