This CUMMINS Valve Guide Set (P/N: 3202210) is engineered for Cummins K6, K19, QSK19G, and G19 series diesel engines, delivering critical valve train stability for commercial and industrial applications. Designed to withstand extreme combustion pressures and temperatures, these guides ensure precise valve alignment, reduce oil consumption, and prevent premature wear in high-stress environments. Ideal for heavy-duty trucks, power generators, and industrial equipment, this set restores engine efficiency and extends service life while maintaining factory-specified performance standards.

Key Advantages:
Crafted from high-density bronze alloy, these guides offer superior heat dissipation and wear resistance compared to standard alternatives. The material’s thermal stability minimizes expansion under extreme temperatures, preventing valve stem seizing and ensuring consistent lubrication. Each guide features precision-honed inner surfaces optimized for oil retention, reducing friction and wear between critical components. This design enhances valve responsiveness and combustion sealing, directly improving fuel efficiency and reducing emissions. The set’s OEM-equivalent dimensionsguarantee seamless integration with Cummins engines, eliminating compatibility issues and ensuring correct valve seating angles for optimal compression retention.

Performance Benefits:
By maintaining exact valve alignment, these guides prevent blow-by and compression loss, common issues in high-mileage diesel engines. Their robust construction reduces the risk of valve stem oil leakage, a critical factor in preventing carbon buildup and maintaining engine cleanliness. For turbocharged variants like the QSK19G, the guides’ reinforced structure handles increased cylinder pressures, safeguarding against deformation and ensuring reliable boost performance.

Usage Tips:
Professional installation with precise reaming is essential to achieve factory-recommended clearances. Pair with high-quality valve stem seals to maximize oil control. Recommended for use during engine overhauls or when addressing excessive oil consumption issues. Verify cylinder head wear before installation to ensure optimal guide seating and longevity.
