AIRSEP Diesel Engine Retrofit Kit
Starting at $800; www.walkerairsep.com
Got a grungy engine room, due to engine oil blow-by? Walker Engineering sells AIRSEP kits for virtually all makes and models of diesel engines, old or new, turbocharged or naturally aspirated. Add an AIRSEP to your diesel and it will either trap blow-by-related vapors, particulates, and oil in the filter or return this unholy trio to the crankcase. Way better than letting your engine room film over with oil, eh? Also, for budget-minded yachtsmen, Walker recently introduced a series of new washable high-performance air filters (shown) that can be substituted for the paper and foam products found in older diesels. They start at about $125 per unit. Not quite as sophisticated as the AIRSEP, but cleaner and greener than the filter elements of yesteryear.
