Keep your high-boost diesel induction path completely pristine with severe-duty oil separator filtration systems from VSE Engineering. Factory crankcase ventilation systems dump oily blow-by gasses back into your intake track, coating your intercooler cores in thick oil sludge and increasing charge-air temperatures. Our custom-engineered, multi-stage catch can packages utilize dual-stage internal condensation paths and fine stainless steel micro-filtration screens to condense, drop, and isolate suspended oil mist cleanly before it can reach your turbocharger. Machined from solid billet aluminum to strict zero-tolerance engineering standards, these heavy-duty catch cans feature custom mounting brackets, quick-drain valves, and premium oil-resistant routing lines. Installing a VSE catch can preserves maximum intercooler thermal efficiency, protects turbocharger compressor blades from oil pitting, and ensures your engine burns nothing but clean, dense air mass under heavy towing or street acceleration.
