I don't think the different bolt heads has anything to do with it. The places you have circled in red show some deformation of the timing trigger. The eBay one has rub marks on the face of the one set of triggers, yours looks like one of the triggers is deformed slightly, as compared to the 'good' JWT one. You might see if there is a measurement for the gap in the triggers in the FSM (it might be a +/- .001 or so), then measure yours. My uncalibrated eyeball says that yours are spread slightly as compared to the 'good' JWT one.

Why don't you just use the O marker on the sprocket or even the key notch.
The scope signals showed a much larger angle discrepancy.
Must be slipped timing trigger.

Ever since Nissan teamed with Renault quality has turned to sh*t.

From the pictures timing is off by 1 tooth = 7 degrees.

I got the new sprockets/phasers delivered and tried to take some nice pictures. It was hard to get the camera perfectly aligned, but the B one might be very slightly off too.

I rekon if you heat up the ring and tap it one way you should be able to realign.
Then just recheck with scope to see if ok. repeat if necessary. Then weld to secure.
Strange no one on this forum has worked this out? Must be an 09 issue only and people just assume chain is stretched and change everything.

Good news! The last 2 weekends were spent cleaning and reassembling everything. Everything was a success, the camshaft sensor outputs are good, nothing leaks, and the car runs and drives with zero diagnostic codes

I'm planning on doing another flush of the oil and coolant soon to make sure any extra bits of gasket/dust/dirt/cleaners/etc are out since the cover was left open for so long.

Nice pictures.

Start using 10w-40 and see if this reduces oil consumption.

Congratulations, way to push through and get the job done.

Great job cleaning EVERYTHING before reassembly. It's nice seeing that kind of attention to detail when chasing problems and fixing them. Kudos.
