If you look behind the camshaft pulley, on your right, there should be a cutout to allow you to view a dimple thats on the rear of the pulley itself.
Its only viewable for a few degrees and the engine has to be on compression stroke, so number one piston on its way up.
There is a line stamped into the front crankshaft pulley that will line up on an extented casting on the oil pump.
Only when the engine is at TDC wil both those marks be in line, unless of course some wally has put the belt on a few teeth out!
The cam pulley dimple has to be inline with the top of the cam cover flange/gasket although youll often find theres some leeway, but the main thing is to be able to see them both as its critical to cam position vs crank position.
Probably best to have someone wind the engine over slowly ( you can do it yourself on the flat with the gearbox in 5th on the flat) and pull the car towards you (ignition off!) until the cam dimple becomes visible, then go look for the crank marking, theyre usually not particularly prominent especially if its rusted.
