Last August, I bought a 2006 Ford Focus ZX4 SE with 220k miles. So far, it’s been a great car for its age and mileage. I thought at first that it must’ve been very well cared for. In preparation for a long road trip, I’ve spent this past week or so catching up on basic maintenance that the previous owner or owners (and myself) may have missed out on. This includes an oil change earlier this week. Yesterday, I decided to check the spark plugs. When I pulled the ignition coils off, I noticed that every spark plug well was filled all the way to the top in old dirty black oil! All four plugs were submerged! I thought maybe I had a bad valve cover gasket, but this was old dirty oil, not new clean oil (again, I just had the oil changed), and it didn’t appear to be losing oil or leaking any while idling. I sucked out what I could with a turkey baster and soaked up the rest with some paper towels I shoved down inside the wells. They don’t appear to be filling back up at all, so I think maybe it’s ok. But I have to ask, what on earth would have caused this?
