I am not certain why this apparently can not be counted on to stop the trash, but I will certainly defer to Lynn and those with a lot more experience in trashing engines than I have. So its understandably that the racing crowd pushing engines into the very high power and rpm range stand a higher probability of trashing an engine than in aircraft application. In any case, have not trashed an engine to the point of finding metal in the oil (yet).
