LS Steam Vent Kit

The LS Steam Vent Kit by PWR NORTH AMERICA is an essential upgrade for LS engine builds and modifications, designed to manage crankcase pressure and prevent oil migration into the intake manifold. Built for serious engine builders, mechanics, and street machine enthusiasts, this kit addresses a critical cooling and engine longevity concern in LS-based powerplants.

Proper crankcase ventilation prevents oil contamination, improves combustion efficiency, and protects your engine's internal components from pressure-related wear. This vent kit works by routing excess crankcase vapors safely away from the intake system, maintaining optimal pressure dynamics within the block while preventing blow-by contamination. The compact design integrates cleanly into tight engine bays without sacrificing underhood space or requiring extensive re-plumbing.

PWR's engineering focuses on reliability and performance consistency, making this solution ideal for both naturally aspirated and forced-induction LS applications where crankcase management directly impacts ring seal integrity and oil consumption rates. Street rodders, drag racing builds, and stock-displacement engine swaps all benefit from proper crankcase ventilation, particularly in modified applications running higher boost or aggressive cam timing. Installation is straightforward for anyone familiar with LS engine bay layout.
