HPD’s Australian made billet CNC machined oil catch can / oil air separators have been designed to reduce the amount of oil from the engines crank case breather entering the intake system.

The issue is with the oil entering the intake system on modern diesel engines fitted with EGR (exhaust gas recirculation) where the exhaust gas valve is commanded by the ECM (engine control module) to open and allow exhaust gasses back into the inlet mixing with the oil that’s been left as a film inside the inlet manifold, thus this process just keeps on repeating itself, causing the issue of the manifold being blocked or clogged reducing the air flow to the engine’s cylinders, resulting in lack of performance, black smoke, engine wear and even engine failure.

HPD’s oil catch can / oil separators come in universal and complete kits with all required stainless steel laser cut bracketry, correct size hose tail fitting, washable internal stainless mesh filters, cut to size oil resistant hosing, bolts, nuts, washer, spring clamps and installation instructions for each vehicle.
