Caution: engine flushing can cause premature seal failure. There is a filter at the bottom of the oil filler plug therefore it is normal to see dirt in this area. The PRV-6 has a oversize sump and the oil filtering system does an excellent job of cleaning the oil. We don't recommend any type of flushing unless it has been determined that there are foreign contaminants imbedded in the internal oil passages (rare).
