Normally your crankcase (and associated impurities) would be ventilated back through your engine's intake system, usually via a PCV valve. Great for smog laws, not so great for your engine. You run the risk of coating your intake runners, injectors and internals with the residual oil mist discharged from your crankcase.
Now there's a better way to keep your engine's intake system free from the crankcase oil contaminents generated by engine blow-by - with a SAAS fully baffled Oil Catch Can.
Designed for the Australian off-road, the SAAS Billet Oil Catch Can is your engine's best friend.
