Gold Oil Sep./Breather

The Gold Oil Separator/Breather by MOROSO (SKU MOR68780) is an essential component for serious engine builders and modified vehicle enthusiasts who demand precision crankcase ventilation. This push-in breather eliminates problematic pressure buildup in high-performance engines, particularly those running elevated boost levels, aggressive camshafts, or extended rpm ranges where factory PCV systems fall short.

MOROSO's engineering separates crankcase vapors and oil mist from exhaust gases through internal baffling and cyclonic separation technology, allowing clean air to return to the intake while directing oil back to the pan. The gold anodized aluminum construction resists corrosion and heat while keeping component weight minimal—critical for engine bay real estate and thermal management. The compact 4.35 x 4.35 x 5.7-inch footprint integrates easily into tight custom installations.

This separator benefits turbocharged, supercharged, and naturally aspirated engines experiencing excessive blow-by or owners retrofitting modern PCV systems into classic muscle cars and vintage platforms. Installation is straightforward, making this a bolt-on upgrade that significantly improves crankcase breathing efficiency.
