Hi peeps,
I'm misplaced my service manual

and can't for the life of me remember which timing mark on the camshaft is TDC. I've got a mk 1 silvia and the cam sproket has 2 circle marks and 1 arrow/line. Which one is for TDC is it the arrow @ 12 o'clock ?
I know the cranks spot on so can anyone help whilst I look for my service book please !!
Thanks
Si
