Oil Catch – Provent

With late model diesel emissions systems they are required to return internal fumes from the top of the crankcase and back to the Air intake system. This air often has tiny droplets of oil called Blow-by, and over time accumulate clogging up Air Intake Manifolds, Intercoolers and Turbo Chargers, generally reducing performance of your vehicle. EGR Valves & Coolers are also affected turning the normally dry carbon or soot into a sludgy tar like substance again slowly reducing performance and economy of your vehicle over time.
