SUMMARY
This discussion centers on the measurement and management of engine blow-by, specifically in the context of the Lancer Evo 8. Blow-by gases typically exit the crankcase and are routed into the intake system after the Mass Air Flow (MAF) sensor, passing through the turbocharger and intercooler before being combusted in the engine. This process can lead to oil coating the intercooler, reducing its efficiency, which can be mitigated by installing a catch can. The routing of blow-by gases varies by engine design, with some systems venting directly to the atmosphere or utilizing filtration and oil separation systems.
