AFR misleading? Plugs tell a better story?

Will do leak a test tomorrow. Pulled plugs #1 is black. Noise was from the front, was thinking water pump or alternator, but really don’t think they’re making this noise.
If your engine really did push out the dipstick and puke oil out you have an internal issue causing a massive amount of blowby (pressure) into the crankcase. This would be directly related to your leakage issue - Piston rings.
