As above the chain marks wont line up but you can check to see if the chain has slipped a tooth or 2.
You would have to take off oil pump and cam cover. With piston 1 at TDC the cam lobes at piston 4 (gearbox end) should be pointing diagonally at each other (10 and 2 o clock position roughly).
Also the balance chain runs behind the cam chain.
Hope that helps.
