Valve Cvr Breather Baffl

The MOROSO Valve Cover Breather Baffle (Part Number 68790) is an aluminum bolt-on breather component designed to manage crankcase ventilation in high-performance and modified engines. This bolt-on baffle assembly reduces oil carryover into intake systems while maintaining proper crankcase pressure regulation—a critical function in engines running elevated boost, aggressive valve timing, or extended duty cycles where stock ventilation becomes inadequate.

The aluminum construction provides corrosion resistance and minimal weight penalty, measurable at 0.07 lbs with compact overall dimensions of 12.5 x 1.9 x 14.45 inches. As a kit component, this breather baffle integrates with existing valve cover and crankcase systems via bolt-on attachment, making it suitable for retrofit applications without requiring significant engine modification. The baffle's internal geometry is engineered to separate oil mist from crankcase gases before they return to the intake, protecting turbocharger bearings and fuel injectors from oil contamination—a common failure point in high-output applications.

This component is intended for users building or maintaining performance engines, turbo systems, supercharged platforms, or engines operating at sustained high RPM or boost levels where stock crankcase ventilation proves insufficient. Mechanics, engine builders, and serious enthusiasts working on street performance, track, or motorsport applications will recognize the MOROSO brand's reputation for precision ventilation and oil management solutions. Whether upgrading a turbocharged build or managing blow-by in a modified naturally aspirated engine, this breather baffle addresses a fundamental mechanical requirement that stock systems often overlook.
