LS Oil Gally Bypass

The DERALE LS Oil Galley Bypass is a precision-engineered component designed specifically for LS-based engine builders and performance enthusiasts who require reliable oil distribution under extreme operating conditions. This bypass valve is particularly beneficial in high-performance LS builds, especially those utilizing forced induction or nitrous oxide applications where oil pressure can exceed safe limits.

The DERALE galley bypass features a spring-loaded poppet valve mechanism that opens when oil pressure surpasses a calibrated threshold. This design diverts excess oil back to the pan, preventing dangerous pressure buildup throughout the engine block and maintaining optimal pressure to critical bearing surfaces. This targeted approach helps mitigate the risk of oil starvation in galleries or crankshaft journals, which can be a common failure point in boosted LS engines.

Ideal for turbocharged or supercharged LS builds, the compact design of 2.75 x 1.4 x 3.7 inches integrates seamlessly into existing LS block configurations without requiring major modifications. Weighing only 0.09 lbs, this lightweight component adds negligible weight to your overall engine package, making it a valuable addition for those looking to enhance performance while maintaining reliability.
