    I have a 2008 Ford E150 4.6. It has 179,000 miles and has been well maintained. Recently, I was on a 250 mile round trip service call. It drove perfectly, as normal all the way there. But, when I started it to leave, it had a noticeable miss. The miss seemed to come and go. When I returned...

When I took the valve cover off I cracked it (missed a bolt and tried to pry like a damn fool) and I’ve seen oil building up...

    Hey all, so I have an 04 F150 with the 5.4L V8. I recently changed my spark plugs and coil packs, but now I'm getting a CEL indicating a misfire on Cylinder 3. I've also changed out the Bank 1 Camshaft Position Sensor but with no luck. I happen to have a Bluetooth dongle attached to the OBD2...
