Misfire 5,6,7 & CPS Bank2 after OPG/CG

[esacteksab]

I hang my head in shame asking for help. Put in OPG/CG yesterday. Everything was going well, too well. Put it back together. Fired right up. Oil pressure is good...but missing. Codes galore. Misfires on 5, 6, 7 (not 8) and Cam Position Sensor A/B on Bank2

I thought I got a little aggressive with the wiring harness on the valve cover.

If I had jumped a tooth, shouldn't I see a miss on 8?

I checked and double checked. But I could have gotten it wrong.

But before I tear this thing apart again. Anyone have any tips? Something I might be missing?

Thanks much!

Your timing is off like I was. Take it apart and retime

You experienced the same thing? Do I need to do anything special since it is now out of time?

No just perform the timing procedure word for word. Align the passengers side cam sprocket with the R and the drivers with the L.

Also get a water pump gasket maybe. Mine swelled up and was impossible to reuse.

Got a question:

Step 6:

Using the special tool, rotate the crankshaft clockwise one complete revolution.

# My Comment # The crank is at the 5 o'clock position after installing the LH chain.

Step 7.

Using the special tool, rotate the crankshaft clockwise until the keyway is at the 12 o'clock position.

So do I go 5 o'clock -> 5 o'clock -> 12 o'clock (5 o'clock + one complete revolution, then the remainder of the way to 12 o'clock) or do I go from 5 o'clock to 12 o'clock?

This...just curious, but how was it done the first time?

That's where I went wrong. I went 5 o'clock to 12 o'clock. I truly hope it is this.

Thanks much!

I think roki187 did the same thing. A lot different timing the 15-16 compared to 11-14.

I've never done an 11-14. My first Ford. My first DOHC engine. All new to me. I'm just glad it started/ran and didn't bang the valves.

You go 5-5 and then a to 12.

This is it. If you dont pay close attention you skip that step.

Yep. Totally looked over it. And it was all going so smoothly!

This has probably happened to more people then you think, my guy did the same thing when doing mine

So did I. Retimed and all was good.

Did you find out with misfires or? I'm curious if anyone ran theirs with 5 to 12 rather than 5 to 5 to 12. And how did you get the links to line back up?
