2001-2019 Duramax PPE Threaded 13/16"-16 Oil Filter Adapter (114000551)2001 2019 Duramax PPE Threaded 13 16" 16 Oil Filter Adapter (114000551) The CAT 1R 1807 oil filter was designed to function vertically so it lacks an anti drain back valve. When the CAT oil filter is mounted on a Duramax it is angled horizontally. Without the anti drain back valve, dirty oil flows back into the internals every time the engine is shut off. PPE recognized the need for a better filter product made specifically for the Duramax engine.

we usually suggest not changing engine oil until after the engine is started
