If its a single cam engine the top dead center marks will be on the crank sprocket and the oil pump housing. (notches facing upward) and on the cam sprocket the notch is on the cam cover. You musnt remove it when timing the engine sprockets. . On DUAL cam 2.0 the intake and exhaust cams have 2 marks. the intake (rear sprocket) will have a notch facing up and one toward the front of the car. The exhaust cam sprocket(front one) will have a mark facing upward and the other aligning with the intake one but it will be facing rear. They must be pointing towards each other. the crank sprocket is the same as the single cam alingment.
there are two kinds of timing marks. one is for ignition timing and one for valve timing.

All timing gears. You have to disassemble the entire front of the truck and engine to access.

No you do not , the timing will not change but take the car on the interstate and do about 2 or 3 heavy(foot to the floor) wide open throttle applications this will reset the baro sensor and change the settings for the elevation you are at.

Many Fords of that vintage required that a jumper be placed on a socket near the distributor. Without the jumper in place it's not possible to change the timing of the engine. Install the jumper, set the timing with a timing light THEN remove the jumper and it should stay. You'll need to get a reference manual to identify the jumper location and to determine the proper timing advance settings.
Try buying a manual from Haynes www.haynes.co.uk Your car may well not have adjustable timing.. It could be controlled by an engine management system, in the case of ignition timing. Valve timing is controlled by the timing chain and not adjustable. Failing that, I have adjusted (old style) timing myself by ear. It seems more accurate than a cheap timing light in most cases! Good Luck, Mick
it should have a timing chain
It doesn't have timing..
