You need a Catch-Can!
10 Mar 2024
Crankcase pressure, a common issue in engines, is primarily caused by blow-by, where combustion gases escape past the piston rings into the crankcase due to worn components or higher cylinder pressure as found in boosted engines. This pressure can impact engine performance by disrupting proper air and oil circulation. Managing crankcase pressure through effective ventilation methods, such as a catch can, is crucial to prevent oil residue buildup. Proper ventilation helps maintain optimal engine function and is essential in any engine build to combat blow-by and ensure consistent performance.
