Clearance Oil Pressure Relief Valve for Engine Oil Pressure Regulation
For LS and DOD engine conversions into classic chassis, the CLEARANCE-Oil Pressure Relief Valve is engineered to clamp oil surges before they threaten bearings and seals. It mounts above the filter inside the pan and taps into the bypass channel to relieve pressures that exceed GM factory limits for Gen 4 VVT and AFM powerplants. The precision spring assembly matches the original cracking threshold so variable valve timing and cylinder deactivation routines run with factory accuracy under all loads. With a simple installation at the stock filter location and broad fitment across Chevy and GM truck engines, this solution ensures oil pressure control for reliable long term protection in LS and DOD swaps.
Strategic In Pan Mounting for Immediate Pressure Control
The relief valve installs directly above the oil filter inside the oil pan to intercept excess pressure at its source. By tapping into the factory bypass channel, it shortens the path oil must travel before relief, cutting response time and reducing internal turbulence. This targeted placement prevents spikes from reaching critical bearing surfaces and seal areas. As a result, sudden throttle shifts or heavy load conditions do not translate into damaging pressure surges.
Factory Calibrated Spring Preserving VVT and AFM Harmony
At the heart of the valve is a precision spring assembly set to match GM's original cracking pressure for Gen 4 VVT and AFM engines. This exacting calibration ensures variable valve timing and cylinder deactivation routines operate with factory accuracy under varied loads. By replicating the OE threshold, oil pressure remains consistent for cam phasing events and deactivated cylinders still receive proper lubrication. The result is seamless integration with engine controls and stable performance during towing or spirited driving.
Straightforward Filter Location Installation
Fitting the valve is as simple as removing the oil pan and seating the unit on the stock filter gasket surface. No extra adapters or machining are required, and technicians need only basic hand tools and a torque wrench. This clear process cuts installation time, limits the chance for error, and makes it ideal for fresh engine swaps or routine service. Dependable sealing and consistent mounting points ensure reliable operation from the first start.
Critical Bearing and Seal Protection Through Pressure Management
Unchecked oil surges can erode seal materials and cause cavitation that starves bearings of lubricant. By clamping peak pressure at the correct factory level, the relief valve maintains a stable oil film across cam lobes, lifters, and crank bearings. This steady flow prevents foam formation and reduces wear on rotating and reciprocating parts. Over time, engines benefit from more predictable maintenance intervals and enhanced component longevity.
Designed to deliver precise oil pressure control for LS and DOD conversions, this valve ensures dependable engine protection.
