You don't. Like many (perhaps most?) modern overhead-cam engines, the valves and lifters are "adjusted" hydraulically, by the engine oil. As long as there is always enough oil in the engine, you don't need to worry about valve adjustment.

If, by chance, you're asking because you are hearing what you think is valve noise, the first thing to do is check the oil. Saturn S-series cars are known to burn oil. A quart of consumption every 500 miles is not unusual. There are ways you can reduce the oil burning, but in the end, it has little to no effect on the car's performance (contrary to popular belief). Still, it's important to check your oil EVERY time you buy gas. Don't let it go more than about a quart low. That should keep the engine running quiet and smooth, and help it last a long time.

Valves need adjusting or they are dirty or worn. Cherokees are notorious for having cracked exhaust headers, which would also make a ticking noise.Its probably the lifters.

The 1993 Saturn used a self adjusting hydraulic clutch system on the manual transmission vehicles. As such, the clutch never needs adjustment. If you're having trouble with the clutch, it is most likely because of a worn or damaged clutch assembly.

I think you will find that the lifters are hydraulic which means they are non adjustable. They either need replacing or the rockers need replacing.

70 is little high for the oil pressure. It sounds like their could be some blockage in the oil holes that run to the top of the engine. The ticking could be coming from the lifters or valves not getting enough oil.

You need shims. Not a DIY job. Take it to a pro. You need a feeler gauge and a 10mm wrench, or a DenLors 648827 specialty tool. The adjustments are made with screw adjusters. Certain procedure must be followed, with four positions of the crank and adjusting corresponding valves per cylinder.
