I have been searching amongst several forums on this system, but haven't seen any long term reports as to how it's working out. A couple questions I have been pondering is 1. Has it lowered measured temps in the oil? 2. Has it affected the scavenging (sumping) of the engine? 3. Has is reduced or eliminated excessive valvetrain noise? 4. Has it maintained oil pressure over extended run times? 5. would you recommend it, if so, for what builds? All or just certain engine sizes? Please chime in with your experiences.
