they dont have marks but use pins to lock pulleys. need to put tool in flywheel through hole underneath engine, (near sump) to lock flywheel whilst crank pulley removed. under crank pulley is a ring with hole in, and a hole in engine block, 12 o clock is timed up. camshaft pulley has hole in about 2 o clock. diesel pump has hole at 12 o clock which should line up when crank and cam lined up. ask more if struggling.
