Simply place high-flow stainless steel screen on a new standard oil filter before filter is installed. Screen traps debris before it enters filter. Remove and inspect screen the next time you change oil. The type and amount of trapped material will indicate the condition of your bearings, camshaft, lifters, etc. Bypass hole in screen provides oil flow for cold starts and prevents loss of oil pressure should screen become clogged
