Oil Valley Block Off Plugs for Chevy, GM, Oldsmobile, Cadillac 2005-2018 Gen IV & 2014-Current Gen V

Quantity 8 AFM/DOD plugs used to block oil passages in 2005-2018 Gen IV / V engines. Note: These plugs are for use with the original DOD/AFM valley cover. Will not fit with non-DOD valley covers.

These can be used to block AFM oil galleys under the VLOM plate. The plugs install by slightly tapping the plugs into the oil galley hole.

Install until flush with bottom lip of the plug. If plugs ever need removed the top are tapped to allow for easy removal (4mm x .7 thread size). See our pictures of them installed.

These are commonly used when changing the DOD/AFM Lifters to traditional LS/LS7 style lifters. NOTE: these plugs can not be used with a non-DOD valley cover or aftermarket valley cover. They are designed to fit with the original DOD/AFM valley cover.
