Oil Drain Plug Washer Replacement & Fumoto Valve Upgrade - 7M Engine

Problem

Need to identify the correct oil drain plug crush washer for 7M engine oil changes, and potential upgrade to a drain valve to eliminate messy oil changes due to the angled drain plug on the 7M oil pan.

Oil leak from drain plug area if washer is missing or reusedMessy oil changes due to oil dripping down arm from angled drain plug locationUncertainty about correct washer size and part number

Root Cause

The 7M oil drain plug uses a crush-type washer (gasket) that should be replaced at each oil change to ensure a proper seal. The drain plug sits at approximately a 45-degree angle on the oil pan, making oil changes messy and complicating aftermarket valve fitment.
