Alright I'll just look at the cam lobes then.
Thanks

 

What about DBW 06-09 non-US (F20C) cars? Any evidence they're affected as well?

 

I know this is an old post, but all 4 stroke engines have the piston come to TDC --- twice per each complete cycle. Intake-> compression -> ignition -> exhaust. Therefore, it requires two rotations of the crankshaft, or 720-degrees of crankshaft revolutions (360 x 2) to complete one cycle. The photo has cylinder #1, 360-degrees out-of-phase from TDC. Just rotate the crank around one more complete 360-degrees and #1 will be at TDC.

The photo proves that #1 and #4 rotate at the same timing --- just one revolution of the crank or 360-degrees out-of-phase of each other.

 

windhund: It's a good explanation and I get all that.
What got me worried though was that WSM calls for you to check cyl1 when all TDC marks line up, this is not possible on my motor regardless on how many turns you spin the crank.

 

Hmm... If you turn crank to where the lobes are at 10pm and 2pm (or TDC on Cylinder #1) --- where are the marks on the cam pulleys? Maybe the crank pulley was replaced incorrectly?

The engine did run ok?

 

Yes car runs great and valves were pretty close to spec.
I just had the crank pulley removed and I don't think it's possible to mount it more than one way.
It's hard to tell from the picture but intake cam has the mark at 3pm and exhaust is at 9pm.

 

Those aftermarket cams? Or pulleys?

 

No as far as I know everything is stock.

 

Possible that the right cam gear was put on the left cam? And vice versa?

 

Hmmm yes that might actually be it, if it is in fact possible?
Wonder if it was a mistake at the Honda factory.
