Oil Pressure Relief Valve for Consistent Engine Oil Pressure Regulation
When modern LS or DOD engines are dropped into classic frames, sudden pressure surges can threaten bearings and seals; the CLEARANCE-Oil Pressure Relief Valve controls those spikes by clamping excess pressure at the pan filter interface. Direct pan mounting above the filter taps the factory bypass channel and kicks in precisely at the OEM cracking threshold specified for Gen 4 VVT and AFM systems. Installation requires only basic hand tools and aligns with the stock gasket surface, eliminating the need for custom fittings or adapters. By maintaining consistent oil pressure during cam phasing and cylinder deactivation cycles, this valve effectively preserves lubrication film across critical components throughout daily use and demanding conditions.
Pan Mounted Relief for Rapid Oil Pressure Regulation
By locating the valve directly above the filter inside the oil pan, pressure spikes are controlled at the point of origin. This short path to the factory bypass channel means oil is diverted immediately once preset limits are reached. As a result, internal turbulence is reduced and bearing surfaces are protected from sudden hammer effects. Fast actuation under varying load keeps lubrication consistent when timing events demand quick changes.
Precision Spring Assembly Matched to Gen 4 VVT and AFM Specifications
The valve's spring set is calibrated to mirror the original cracking threshold for Gen 4 variable valve timing and active fuel management designs. This precise tuning ensures cam phasing and cylinder deactivation cycles stay within safe oil pressure margins. Consistent actuation avoids pressure swings that could disrupt control logic or wear components prematurely. Matching oem settings promotes seamless integration and reliable performance under every driving scenario.
Streamlined Installation Using Factory Gasket Surface
No custom adapters or machining steps are needed to install this relief valve. Removal of the oil pan and seating against the stock filter gasket surface is all that is required. Technicians can complete the job with basic hand tools and a torque wrench, cutting down on both time and complexity. Factory hardware secures the unit in place and ensures a dependable seal for worry free operation.
Continuous Protection for Bearings Seals and Oil Film
Unchecked pressure surges can erode seals and create cavitation that robs bearings of vital lubrication. By clamping excess pressure at a controlled threshold, the valve maintains a uniform oil film across crank journals, cam surfaces and lifters. Steady flow prevents air entrainment and foam formation under heavy throttle or towing loads. Over time this protection extends service intervals and promotes durable engine health.
Designed for precise pressure management and reliable engine protection, this valve ensures consistent lubrication across critical components for long term engine health.
