The positive crankcase verticulation (PCV) valve is a one-way line restrictor that takes gases from the crankcase and redirects them to get burned in the engine. Clampy's PCV valve seemed fine, but we replaced it with a new one for good measure. Then we checked the engine's timing. This was set at 8 degrees before top dead center and the manufacturer's suggested setting was 5 degrees.
