Pop-It Valve

The Pop-It Valve by Stock Car Prod-Oil Pumps is a precision pressure relief component designed for high-performance engine builders and mechanics working with custom oil pump systems. This compact valve addresses a critical need in modified engines where standard pump assemblies may generate excessive system pressure during cold starts or peak RPM operation. Built for enthusiasts who demand reliability in street performance, racing, and heavy-duty applications, the Pop-It Valve offers a straightforward solution to pressure management without requiring complex electronic controls.

The Pop-It Valve operates as a mechanical pressure relief device, cracking open at a calibrated threshold to route excess oil back to the pan or reservoir. Its compact footprint—measuring 2.4 by 0.6 by 4.05 inches and weighing just 0.03 lbs—allows seamless integration into tight engine compartments and existing pump assemblies. The lightweight design means minimal parasitic load, while the precision-manufactured internals ensure repeatable, reliable pressure regulation across varying engine speeds and temperatures. This direct-action valve eliminates pressure spikes that can damage gaskets, seals, and bearing surfaces in modified powerplants.

The Pop-It Valve is ideal for custom engine builds, high-displacement stroker motors, and applications running aftermarket high-volume oil pumps where factory bypass systems prove inadequate. Professional mechanics and serious gearheads benefit most when building turbocharged, supercharged, or naturally aspirated motors that see extended high-RPM duty. Installation pairs perfectly with aftermarket pump upgrades, allowing builders to fine-tune system pressure for optimal bearing lubrication without risking seal failure. Verify compatibility with your specific pump mounting configuration and pressure requirements before ordering.
