Ecotec Crankcase Vent Valve Cover Breather – Billet PCV Upgrade for Boosted & High-Performance Builds

Eliminate crankcase pressure issues with the BK Racing Ecotec Crankcase Vent Valve Cover Breather — the best billet breather upgrade for GM Ecotec valve covers, providing a high-flow, leak-free solution for positive crankcase ventilation in boosted, supercharged, or high-RPM engines. This precision-machined breather replaces or supplements the factory PCV system, allowing clean venting to atmosphere or catch can while preventing oil blow-by and pressure buildup — essential for Cobalt SS, Ion Redline, HHR SS, Solstice GXP, Saab 9-3, and custom turbo builds.

CNC-crafted from billet aluminum with integrated baffle and filter media, this breather ensures oil separation and dry venting — reducing contamination in intercoolers or intakes during aggressive driving or high boost.

Key Features:

• Billet aluminum construction for durability and heat resistance
• Integrated baffle and filter for effective oil mist separation
• High-flow design with barbed outlet for hose connection (to catch can or atmosphere)
• Direct replacement or add-on fitting for Ecotec valve cover ports

Performance Benefits:

• Reduces crankcase pressure for better ring seal and reduced oil consumption
• Prevents boost leaks through factory PCV in high-pressure applications
• Cleaner intake charge and reduced detonation risk in turbo/supercharged setups
• Supports higher power levels without PCV failure or blow-by
• Pairs perfectly with BK Racing catch cans, valve covers, and boost upgrades

Compatibility:

• GM Ecotec engines:
  • 2.0L (LSJ supercharged, LNF/LDK/LHU turbo)
  • 2.2L (L61, LAP)
  • 2.4L (LE5, LE9, LAT, LAF, LEA)
• Chevrolet Cobalt (including SS), HHR (including SS), Malibu; Pontiac Solstice/G5/G6; Saturn Ion (including Redline), Sky, Vue, Aura; Saab 9-3; and custom swaps
• Fits standard valve cover PCV ports — barbed outlet for 3/8" or 1/2" hose

Important Notes:

• Designed for vent-to-atmosphere or catch can setups (requires hose routing)
• May require PCV valve bypass or tuning adjustments for emissions compliance
• Off-road and competition use only

Installation Note: Simple press or screw-in fit. Route hose securely away from heat/moving parts. Professional setup recommended for boosted applications.
