I have my head off and when the machine shop had it they cleaned it for me removeing the marks from the cam sprockets. I have looked at Alldata and WIS and nowhere can I find how to now line up the cams. The only refernce says use 4mm pins but not for the AMG. So if any body has a clue please let me know!
Thanks

All M104 engines time at TDC..& the alignment of the camshafts are with pins.

do the pins just go at 12 oclock? I also do not see one on the intake?

No, they go in at 9 on the intake & 3 on the exhaust..

they actually sit on the head & slide into the camshaft flange.

so the pins go in the holes in between the cams, not on the outside of the cams? Thats just useing the 4mm holes like alldata says? When I looked it said all but AMG.
