How does it work? During the process of venting crankcase pressure back through your intake track, large amounts of oil in the form of vapors can coat your blower , intake valves, intercooler fins, and even dilute your gas lowering its level. This happens on all engines and is even worse when supercharged and turbocharged as crankcase pressures are increased. To combat this, we have developed an oil separator of our own design. Milled from solid billet aluminum this is a rock-solid piece. It has a knurled tank base for easy removal to drain the spent oil and an O-ring seal to prevent any leaks.
