I have a 2002 Ford Focus coming up on 150k… still drives fine, but when I went to change the plugs today, I found all four of them submerged in oil. Anyone know what’s going on?
You need a new valve cover gasket set.
At the bottom of the spark plug wells on the valve cover are seals. These seals are now leaking and the crankcase pressure is pushing oil past the seals filling the spark plug wells.

Nevermind. Got it - going after a valve cover gasket.
Tester: Thanks - hadn’t refreshed my screen to see that.
Appreciate your help, and the additional insight!
