The BD Diesel 1032170 is a heavy-duty crankcase ventilation (CCV) filter kit engineered for 1999–2003 7.3 Powerstroke diesel engines. Designed as an inline closed-loop oil separation system, it intercepts crankcase blow-by gasses from the driver-side valve cover breather before they enter the turbocharger inlet tract. BD Diesel builds this complete kit with a high-capacity cast aluminum filter housing, internal coalescing filter element, mounting bracket, heavy-duty oil-resistant hoses, clamps, and direct-fit valve cover adapter fittings.

Oil-soaked intercooler boots blowing off under boost, heavy oil coating the turbocharger compressor wheel, degraded intake tract silicone boots, and oil sludge insulating intercooler fins are what this kit cures. From the factory, the 7.3 Powerstroke vents crankcase pressure directly into the air intake boot ahead of the turbo; over time, oil mist coats the turbo blades, drops charge-air cooler thermal efficiency, and softens rubber boots until they split under load. BD Diesel's coalescing filter separates oil droplets and traps aerosolized vapor, collecting engine oil while returning clean air into the intake tract without venting oily smoke into the cabin or dripping oil onto the chassis. It is the complete crankcase ventilation filter system kit only; replacement internal filter elements are sold separately.

It fits 1999–2003 7.3 Powerstroke Ford Super Duty trucks and Excursions equipped with the factory driver-side valve cover crankcase vent adapter.

Mount the aluminum canister assembly securely using the supplied bracket along the frame rail or inner fender location, ensuring the housing remains upright for proper gravity separation and drainage. Remove the factory CCV hose routed from the driver-side valve cover "doghouse" breather to the intake tube, capping the open intake port or utilizing the kit’s return line adapter as instructed. Route the provided heavy-duty hoses smoothly with a downward slope toward the filter canister to avoid oil traps or low spots that can freeze or block crankcase breathing during cold winter operation. Inspect the drain valve periodically and service the coalescing filter element at regular oil change intervals.
