So I recently picked up a 2010 lc from out of town. I had a Toyota dealer do a pre purchase inspection and they recommend replacing the spark plugs. After driving it for a few days and noticing the MPG averaging 13ish I decided to try and tackle changing the spark plugs myself. Unfotunately I found the rear two spark plug wells on the passenger side were full of oil. I could see oil on the outside of the valve cover too. I also noticed a little bit of oil on one of the spark plugs on the driver's side. I'm guessing I need to replace the valve cover gasket and spark plug seals. The LC has 161,000 miles on it.
Anyone ever tackle this? The only write up I could find was on a Tundra forum.
