Blow-by gas in modern engines fitted with exhaust gas recirculation system (EGR). EGR valves direct a proportion of the exhaust gas back into the engine. Oil from the crankcase ventilation system, combined with exhaust particles.
This combination of oil and exhaust particles from the EGR builds up to a point where it blocks inlet manifolds and valves, resulting in reduced engine performance or failure. Fitting a quality Provent catch from VMN can:
Prevent oil and soot contamination entering the clean air intake
Offers protection for turbocharger
Minimises oil consumption*
Prevents oil buildup in intercoolers
Regulates crankcase pressure
Keeps critical engine components clean
Reduces exhaust smoke and odours
*With 98% oil separation efficiency quoted by the manufacturer, our range of catch cans will save you money.
