LIVING IN A VACUUM - CRANKCASE VENTILATION SYSTEM TESTING

摘要

In this article, I will be talking about a subject that does not get much respect or attention among many automotive technicians and that is the engine crankcase ventilation system. Many technicians consider these systems to be pretty simple and trouble-free, but they are often overlooked in their importance as well as their ability to cause rather confusing problems on modern powertrain platforms. It is my goal to show you the importance of considering the crankcase ventilation system in your diagnostic routine and how to test crankcase pressure to determine if the system is working correctly.
