OywhC Oil Valley Block Off Plug Stainless Steel

Description

Product Overview

OywhC presents the Oil Valley Block Off Plug, a precision‑engineered solution designed for GM engines that do not feature Displacement on Demand (DOD) technology. Constructed from high‑quality stainless steel alloy, each plug offers exceptional strength, corrosion resistance, and a perfect fit for the oil passage holes of LSX and LT series engines ranging from 4.8L to 6.2L. The package includes ten plugs—eight for primary use and two spares—ensuring complete coverage for all oil passages. Dimensions are compact at 2.68 x 1.97 x 0.55 inches, weighing only 1.44 ounces, making storage and handling effortless.

Usage

These plugs are ideal for automotive technicians, performance enthusiasts, and DIY owners who need to seal oil passages on 2008‑2023 GM engines such as LS1, LS2, LS3, LS7, L83, LT1, LT4, and LT5. Installation is straightforward: tap the plug into the oil pipe hole until it seats securely, then use the 4mm × 9 thread on the top for future removal if needed. The product excels in scenarios where oil pressure leaks can compromise engine performance, especially after engine swaps or when DOD systems are disabled.
