Oil Pressure Relief Valve for Engine Overpressure Prevention
If you're swapping an LS or LT mill into your chassis, guarding against damaging oil pressure surges is essential and the CLEARANCE-Oil Pressure Relief Valve is engineered to intercept spikes before they compromise bearings and seals. It installs inside the oil pan directly above the filter bypassing excess flow through a precision spring design for consistent oil pressure control on Gen 4 VVT and AFM applications. Crafted to match GM tolerances, this valve ensures smooth operation across Chevy and GM truck engines while simplifying setup for both professional shops and home garages.
Precision Mounting for Consistent Oil Pressure Control
Positioned directly above the oil filter inside the pan, this relief valve leverages a precision spring assembly to divert excess flow the instant pressure exceeds safe limits. By situating the unit at the oil filter bypass point, it minimizes response time and maintains consistent oil pressure control even during rapid throttle changes. This direct-mount approach reduces turbulence in the sump and ensures the valve operates within the designed cracking range. The result is a steady pressure level that protects critical bearings and keeps lubrication pathways clear under all driving conditions.
Safeguarding Engine Components from Overpressure Strain
Excessive oil pressure can place undue stress on seals, gaskets, and bearing clearances, leading to accelerated wear or sudden leaks. This relief valve intercepts harmful spikes before they reach sensitive areas, preserving seal integrity and extending component life. By regulating peak pressure, it helps prevent cavitation and foam formation that can starve high-load surfaces of vital lubrication. Overall, this protection contributes to smoother operation and reduces the risk of premature engine failure.
Engineered Compatibility with Gen 4 VVT and AFM Systems
Specifically designed to match GM's Gen 4 variable valve timing and active fuel management platforms, the valve housing and spring rates adhere to factory tolerances for both Chevy and GM truck engines. This precision fit ensures seamless integration without altering oiling pathways or complicating the existing sump layout. It supports all original VVT and AFM functionality by maintaining stable pressure during cam phasing events and cylinder deactivation cycles. The result is reliable performance across a wide RPM range and load spectrum.
Streamlined Installation for LS DOD and VVT Engines
Whether you're working on an LS swap or a direct-injection DOD block, this relief valve drops neatly into the oil pan above the filter cartridge without the need for welding or machining. The kit arrives as a single, self-contained unit complete with calibrated spring and retainer, allowing mechanics and home builders to complete the upgrade in minimal time. No special tools or manifold modifications are required, and standard pan removal is all that's needed. This streamlined process gets your engine back on the road faster while delivering essential pressure protection.
Engineered for a precise fit and reliable protection, this relief valve ensures stable oil pressure on every build.
