Re: 288 stuck valves

This seems to be rather common in newly overhauled engines that had the valve guides replaced and fitted to modern specs. This new fuel seems t gum up the valves with this close tolerance after just a short time of non use. I have had a 327 gum up after just a couple of months even when the engine was started and brought up to temperature about once a week. Finally, the valves had to be removed to loosen them. The bottom line is that our straight eight engines are better off if used regularly.
I have had good luck with a Marvel Mystery oil upper cylinder lubricator. It seems to solve the problem.
