somebody? somewhere? stated that they wished they could see the inside of my 197k mile FJ 4.0L engine with a valve cover removed. We'll, I liked this idea, so they are getting their wish. Below are pics I took recently of the engine w/passenger side valve cover off. Looks pretty goodl to me. I think it can be seen on the inside of the valve cover where the Mobil Delvac 1 ESP has been doing some light cleaning. That would explain where the crud at the bottom of each the filter pleats when I cut it open at the last oil & filter change 1500 miles ago.. I cleaned the inside of the valve cover, then put it back together. What say you? [Linked Image] [Linked Image] [Linked Image] [Linked Image] [Linked Image]
