[QUOTE="Fred W, post: 971881, member: 3828"] Interesting that you had already taken steps to decarbonize. Maybe what you used is not aggressive enough? :unsure: It may be that yours is a rare example where the valves came from the factory a bit wider. Or maybe your feeler gauges are FUBAR? I'd just stick to the standard valve check schedule, unless you notice something awry. If the clearances are growing, unlike with the opposite case of shrinking clearances, it isn't a dangerous thing. It would just eventually cause degraded engine performance due to altered timing. If the next check shows the clearances are bigger still, then you might want to consider a more radical decarbonizing regime. [/QUOTE]
