yes, but on WHICH tdc  ? - the piston comes up on both compression and end
of intake/start of exhaust.
You watch # 3 valves to tell when it's on # 1 tdc on compression.
You can also look at the cam lobes - they need to be pointing down for it to
be on compression, the lobes for # 1.

Just to confirm, I double checked my '75-'92 VW Rabbit Haynes. Says
the same as you wrote for timing marks on the SOHC engine. I can't say
for sure if same for Tiico though.

Spark plug wires correct?

Are both valves closed on #1 when rotor at #1?

Is there an inspection hole to look for TDC indicator on flywheel?

And to be sure, are you counting cylinders from drivebelt to tranny?
