LS Engine Active Fuel Management Oil Consumption Solved
Under high-speed engine operation, the AFM (active fuel management) pressure relief valve can spray an excessive amount of oil, leading to deposit formations in piston ring grooves and cracked or fouled spark plugs. To prevent overspray issues, install a Melling oil pressure relief valve deflector right over the top of the OE oil pressure relief valve in your crankcase, and you are good to go!
