Where are the timing marks on a 1991 F-150 4.9L and what do they look like?

Looking at the engine from the front of the vehicle, find the

crankshaft pulley, it should be below the fan pulley (toward the

ground). There is a small mark on the crankshaft pulley. Also

mounted on the engine the is a piece of metal that looks like teeth

kinda looks something like this - ---vvvvvvvvvv/\vvv--- Those are

your timing marks. Each tooth is one degree and the larger concave

space is TDC of the compression stroke for the #1 cylinder
