Earlier this week, I had the valves and Jake adjusted on my 8V92.
This is the passenger side valve, Jake and injector assembly with the valve cover removed. The valve springs are visible on each side of the injectors. The injectors are the devices with 2 wires going to each. The fuel lines to the injectors are seen at the bottom of the photo. The Jakes are on top. There are 2 masters, located in the center with the round solenoids and a slave located at each end of the masters.
A close up of the injector (center bottom, valve on each side of the injector (the Detroit Diesels used 2 exhaust valves and no intake valves), and the Jake at the top of the photo.
I also have an exhaust leak on the driver side exhaust manifold. I hope to get that resolved in the next couple of weeks.
