Direction Plus™ ProVent® Catch Can Systems for 4WDs

Direction Plus, ProVent oil separator kits protect your modern diesel engine by sustainably reducing the amount of oil entering the engine from blow-by gas in the crankcase ventilation system.

The problem is compounded with modern engines fitted with exhaust gas recirculation systems (EGR) which route a proportion of the exhaust gas back into the engine. With the presence of oil from the crankcase ventilation system, the oil collects the exhaust particles. The combination of oil and exhaust particles build up to a point where it blocks inlet manifolds and valves, resulting in reduced engine performance or failure.

Fitting a Direction Plus ProVent system prevents your engine from experiencing a progressive reduction in performance.  The systems, are specifically designed for their ability to separate and redirect oil and air from  the blow-by gas produced from within the crank case. The system also provides the option of returning the oil back to the sump.

For the ultimate defence against oil and soot contamination, invest in a Direction Plus ProVent oil separator kit.
