Clogged crankcase ventilation systems often are overlooked causes of engine oil leaks. Savvy service personnel keep these systems at the top of their mental checklists for solving oil leaks. I'll ...

Every engine has some sort of crankcase breathing system. The internal combustion process creates pressure, some of which makes its way past the piston rings-along with fuel vapors-and into the rest ...

Although some maintenance schedules include an interval for replacing the positive crankcase ventilation, or PCV, valve, others may not. In the latter case, a general recommendation is to replace the ...

The fleet landscape in 2026 has fundamentally changed: AI-powered diagnostic platforms now predict component failures with 85–95% accuracy, yet 62% of unplanned downtime remains preventable because ...

The PCV (Positive Crankcase Ventilation) system is designed to regulate and remove fumes from the engine crankcase, and to alleviate crankcase pressure which could cause oil leaks or seal damage. The ...

Regardless of what type of vehicle you drive, if it was built in the last few decades, its engine has some form of emissions control system designed to reduce the harmful environmental impacts of ...
