2013 Mazda 3 2.0L Skyactiv - 98,660 miles.

Oil change history: mostly PP 0w20 at 5K-7.5K intervals. It did have one run of M1 early on that was about 13k by accident.

Why did you have to remove the valve cover?

I've had a couple of Mazda MZR engines (Ford Duratechs actually) and the valve cover gasket leaking into the spark plug tubes is quite common after several thousand miles. I wonder if the Skyactive engines have this issue?

I'm assuming a leak but @ 98k miles (6yrs old) that seems kinda early IMO but maybe it's normal for these engines??🤔

Looks great but I too am curious about the cause. I do assume there’s some ~100k ish spark plug change out, and it they show signs of oil, then...

Yes - oil seepage around the Oil Control Valve.

No wipedown - except on the areas where the gasket and RTV will sit. The oil was changed a few hours before this picture was taken.
