Thanks for that jem of information Jay. That makes a lot of sense to advance the cam shaft by moving the dowel locating pin. That helps me a lot in making sense of what I saw earlier today.

I pulled the valve cover a few hours ago and check the marks and timing of the valves. The exhaust is pretty much spot on. But the intake valves are opening about 25 deg early...oh! oh!...looks like I must have assembled the timing with the camshaft adjuster in the fully advanced setting as opposed to the fully retarded position.

Photo shows inlet sprocket 4mm timing hole advanced due to AMG modified dowel location (3.5mm drill bit inserted after sprocket positioned to illustrate new AMG position).

Question: Can anyone confirm that if I set-up the timing for my M104 AMG as illustrated in the photos, but, correct the VVT to full retard, that this will be the correct procedure for the M104 AMG?



General view.



Exhaust sprocket 4mm timing hole spot on.



Settings were at TDC.
