What Does the PTC Diesel Engine Oil Separator Do on a Ford 6.7L Power Stroke?
Published 10/31/2026
Question:
Ive got a 2015 Ford F-250 with the 6.7L Power Stroke diesel, and Ive been doing some maintenance on it before winter. My buddy mentioned replacing the crankcase oil separator, but Im not really familiar with what it does. I found the PTC oil separator PTC64EQ and wanted to know if its a direct replacement for the factory one. Is this something that actually helps keep the engine cleaner, or is it just another filter I need to worry about?

Hey Chris, the PTC Diesel Engine Oil Separator # PTC64EQ is a direct replacement for the factory oil separator on your 2015 Ford F-250 with the 6.7L Power Stroke, and it actually does a pretty important job! Basically, your engine produces oily vapors while it's running, and without a working separator, that oil can make its way into the intake system and leave behind buildup over time. The separator catches that oil mist before it gets that far, helping keep things cleaner and your engine running the way it should.
What I like about the PTC is that it's made to match the original Ford part, so there's no special modifications needed to install it. It's a nice way to help protect your engine from unnecessary buildup, especially if you're planning to keep your truck for a long time.
Have you been noticing oil buildup around your intake, or are you just staying ahead of things with some routine maintenance?
