There will be marks on the cam gear and the crank gear. Some are dots, some are diamond shaped. You just line the two up so the top mark is directly over mark on the crank. You may have to turn the crank by hand which is easier with all the plugs out, to line it up. You will want to drain oil,change filter, and put in new oil to get rid of contaminated oil in oilpan.
If you fail, you are not talking about a lot of money to try to fix the top of the engine compared to engine replacement. For the most part, you could still tow it.
You could ask how much it would cost just to replace the gasket and let someone else bust their knuckles.

These engines are prone to blown head gasket problems. Especially when run hot. If clattering was heard when overheating occurred, that would most likely be pre-ignition from running hot. Check engine oil for presence of coolant (milky, white). Do not replace engine, Just have the head surfaced and replace head gasket. Isolate and repair cause of overheating(water pump, thermostat, electric fan) before running new head.

Ran Hot Won't Start

You just blew your head and gasket. I just had that same thing happen last month. When it over heated is the time that you blew the engine head's gasket. When you kept driving it is when you damaged your engine head. You also should have noticed that the as soon as you put water in the radiator that it was leaking out back of engine from the freeze plug or plugs. Cost of freeze plug is couple bucks "looks like small cup cake tin." The Freeze plug has to be replaced 1st, but depending on how bad the head is damaged you could get off cheap by pouring in a $40 gasket sealer liquid down into the radiator and lots of water to keep the water level up. I would also remove the thermostat and put host back on. Since your car is older that I do not think it ruined the values or rods.

If your Jeep ran hot enough to shut itself down then you likely have at least a blown head gasket for starters. The casue of the overheating also needs to be addressed. Timing gears won't make an engine overheat nor will they cause an engine to lose compression.

If there is not enough compression to let it start, then you need to take it to a shop and have it checked out but you are probably looking at a head gasket and probably a warped or cracked head. Hope this helps.

Overheating issue

You need to get a pressure check on the cooling system. I suspect a bad head gasket. Engine compression leaking into a water passage would force coolant back out of the engine. Hope this helps.

Can you put a socket and ratchet or breaker bar on the damper bolt,, Can you turn the engine over at all?? that is the big bolt on the pulley where the crank is. If you cannot budge the engine, then it is seized up more than likely and the bearings have melted to the crank.

Blown head gasket

Well they are known to blow head gaskets and have intake gasket leaks also. If the car doesnt run it sounds like the gasket blew out between two clynders. If you have the equptment do a compresson test on all 6clynders and see if the are all about the same dont for get to remove the fuel pump relay before you start and un hook the coils
