I could use some help if anyone has any ideas of what I may be doing wrong. The car is procharged. Any help or advice would be greatly appreciated.
During a burnout attempt, I over rev’d the motor. I don't know how high it rev'd but it was well past 8k. Shortly after the incident, white smoke started coming out of the exhaust. I pulled the passenger side oil separator and it was full of oil. A compression test showed zero compression in cylinder 5. All 7 other cylinders showed good compression and were within specified tolerance of each other. Thinking I bent a valve, I pulled the driver side head and cams. After removing the cams, it appeared that the valves were all closed. I put the head back on and a leak-down showed the cylinder was holding pressure again. I replaced the driver-side cams and put everything back together. After starting the car, there was some smoke coming from the exhaust but stopped shortly after the motor warmed up. When I noticed the motor vibrating abnormally, I shut the car down and pulled the DTC codes. I got P0345, P0349, P0390, P0934. Thinking I messed the timing up, I tore everything back down to the cams and tried to retime the motor. This is the first time I’ve removed cams or timing from any vehicle.

- I have the ford shop manual showing detailed removal and installation procedures.
- Installation - Driver side
- Set crankshaft keyway to 5 o’clock.
- Set the cams in the head in the correct clock position
- Set secondary timing chain double and single black link on the phasers to the appropriate position
- Set driver side primary timing chain with black link on sprocket gear timing mark to cam phaser left timing mark. Phaser looks to be in the correct clock position.
- Rotated crankshaft clockwise to keyway at 12 o’clock
- Passenger side primary and secondary timing chains set similar to above.
- Pull all the cams and ensure the all cylinders are still holding pressure.
- Retime the motor
- I recently discovered there is a crank relearn function on the nguage. I had believed that reloading a tune would reset the PCM.
- Check all the cam position sensor wiring for any shorts.
- Compression check each cylinder.
