How We Picked These Ford F350 Diesel Crankcase Filter Kits

We prioritized direct-fit compatibility, clear OE cross-references, and broad Super Duty coverage for the 6.7L Powerstroke platform. Because these parts affect crankcase ventilation and intake cleanliness, we also favored listings that specify model years, replacement numbers, and assembly-style fitment over vague universal claims.

We also looked for practical buyer signals: whether the kit is aimed at a simple replacement, whether it matches factory-style routing, and whether it covers the truck range most owners are shopping for, including 2011-2016 and newer 2019-2026 applications.

Quick Comparison

For the widest coverage, choose PC3Z-6A785-A-style assemblies that span multiple Super Duty years. For older trucks, DC3Z6A785C-compatible kits are a better match. If you’re replacing a failed unit on a later-model F-350, verify the exact year and OE number before ordering, since small changes in factory parts can affect fit.

Key Buying Factors for Ford F350 Diesel Crankcase Filter Kits

Model Year and Engine Match

The most important filter-kit decision is year-specific fitment. Many Ford F350 Diesel Crankcase Filter Kits are made for the 6.7L Powerstroke, but the correct assembly can vary across 2011-2016, 2019-2022, and 2023-2026 trucks.

OE Part-Number Compatibility

Cross-referencing part numbers like DC3Z6A785C, LC3Z-6A785-C, and PC3Z-6A785-A helps narrow the right replacement. If your current part number matches, that’s usually the fastest way to confirm compatibility.

Assembly Versus Filter-Only Replacement

Some listings are full oil separator assemblies, while others emphasize the CCV filter component. If your housing is damaged, warped, or leaking, an assembly replacement is usually the safer choice than just changing the filter element.

Installation and Maintenance Access

Look for a design that supports straightforward service. A good replacement should seat properly, seal cleanly, and make future maintenance easier without forcing unnecessary intake disassembly.

Who Should Buy Which Ford F350 Diesel Crankcase Filter Kits?

Buyers with late-model Super Duty trucks should focus on the newest year-specific compatible assembly and double-check trim and engine fitment. Owners of 2011-2016 trucks should lean toward DC3Z6A785C-compatible replacements for a more exact match. If you want the broadest compatibility window, PC3Z-6A785-A-based options are often the most flexible, but they still need a year-by-year verification before purchase.

If your goal is preventative maintenance rather than urgent repair, choose a well-matched OEM-style replacement that aligns with your current setup. That gives you the best chance of preserving factory-like crankcase ventilation performance while avoiding repeat installation work.
