Is it a cosmetic issue only, or can it eventually cause the engine to seize up?
I’ve seen pics that guys here post when they take off the valve cover, and I see moderate amounts of varnish, and people argue about whether that amount is ok or bad. I just wonder about the significance of a slight amount of varnish. Is it possible that that could cause engine failure, or would it have to be a major case, before it would cause engine failure.
