If your 7.3L Powerstroke is showing signs of oil seepage around the crankcase vent (“doghouse”), worn or flattened CCV O-rings are the most common culprit. This OEM Crankcase CCV Breather Seal O-Ring Kit restores a proper seal between the CCV assembly and valve cover—eliminating leaks and maintaining correct crankcase ventilation.
Over time, factory O-rings degrade from heat, oil exposure, and pressure cycles. Replacing them is a simple, cost-effective repair that prevents bigger issues like oil contamination and engine bay mess.
