i just got back a 16v cylinder head from the machine shop an planning on doing a switch -a roo this week , after reading the WIS 102.983 engine sevice manual and the haynes , it tells TDC is the 0 mark on the crank not the dowel , but i lik e the screw driver method better, the cams have to be lined up at 3 and 9 oclock facing each other , then torqued up to 12Nm the top mark should be around 12 0 clock too




timing in the crank angle degress at 2mm vavle lift

intake valve opens after TDC
left 7 deg
right 0

closes after BDC
left 26 deg
right 0

exhaust Valve opens before BDC
left 0
right 32 deg

Exhaust Valve closes before TDC
left 0
right 13 deg


good luck
