GC4Z6A777B Crankcase Ventilation (CCV) Filter for Ford 6.7L Powerstroke Diesel
GC4Z6A777B CCV filter for Ford 6.7L Powerstroke F250-F550 Super Duty (2017-2019). OEM cross-reference verified. Orders from IXIN Filter.
Description
The GC4Z6A777B CCV filter is a crankcase ventilation filter engineered for Ford Super Duty trucks equipped with the 6.7L Powerstroke diesel engine, covering the 2017-2019 model years. It’s designed to separate oil mist and contaminants from crankcase blow-by gases, helping maintain proper crankcase ventilation, reduce intake system contamination, and protect downstream engine components.
Product Overview
Modern diesel engines generate blow-by gases during normal operation. As explained in this overview of how CCV systems work, a closed crankcase ventilation system gives blow-by gases, pressure, water vapor, and oil mist a controlled path out of the engine while keeping the crankcase from becoming over-pressurized. Without effective filtration, these gases carry oil vapor and contaminants into the intake system, contributing to carbon buildup, reduced efficiency, and increased maintenance needs over time. The GC4Z6A777B crankcase ventilation filter is designed to capture these contaminants before they reach the air intake system, manufactured to meet or exceed OEM specifications for fleet operators, diesel truck owners, maintenance facilities, and aftermarket distributors.

Frequently Asked Questions
What does a CCV filter do? A CCV filter separates oil mist and contaminants from crankcase blow-by gases before they recirculate into the engine’s intake system, helping protect the turbocharger, intercooler, and EGR system from oil-related carbon buildup.
When should the CCV filter be replaced? Replacement intervals vary by operating conditions, but many service guides recommend replacement around every 50,000-60,000 miles, with regular inspection during scheduled maintenance. Always confirm the interval against your specific vehicle’s maintenance schedule.
Is this a direct replacement for GC4Z6A777A, BC3Z6A777A, and FL-2077? Yes. This filter is manufactured as a direct replacement matching the GC4Z6A777B specification, cross-referenced to GC4Z6A777A, BC3Z6A777A, and FL-2077.
Do you offer OEM and wholesale services? Yes. We support OEM production, custom branding, and private-label packaging for distributors and wholesalers.
