Oil Consumption Fix #22-NA-027
If you have a 2020 - 2022 3.0 Duramax Diesel and are experiencing engine oil consumption, you may have a simple fix. Simple, being a loosely used term.
NHTSA has a document showing the possible oil consumption being caused by an internal issue in the camshaft cover. See the video below to find out how to verify your camshaft cover.
I contacted my dealership and they said this could be a risky cause of my oil consumption. Apparently they send the parts to GM to test whether the weld is faulty or not. Is there a way to test this weld without disassembling the motor?
