It is possible that the harmonic balancer has spun.check the rubber around the balancer for cracks or decay.If so replace balancer...
the pointer has its on mounting spot on the front of the block when you bolt it on the pointer will be set
Ford 5.0L V-8s have the timing pointer at the bottom of the timing cover on the vehicle's right side of the harmonic balancer. Look behind the crankshaft pulley (the biggest one, it's at the bottom in the center of the engine). This is bolted to front of the balancer.
near the harmonic balancer, its under the timing pointer.
Timimg marks are on the harmonic balancer and pointer is on the lower timing cover
The timing mark is one the Harmonic balancer and the pointer is attached to the timing cover. Roll the motor over to the timing mark, the be sure and mark the number one plug {marked on the intake manifold} the position of the rotor pointer on the distributer.
Pointer aligned with hash mark on balancer, #1 piston at tdc.
there is only one mark and one pointer
The mark is on the harmonic balancer. The pointer should be visible by looking down from the passenger side of the engine compartment. They're usually bolted to the timing cover.
That would be the biggest and widest mark. Are the first mark on it when turning it clockwise to the pointer.
There are numbers stamped into the harmonic balancer, if you can't see them, take some sand paper and clean the balancer off, you should see the pointer that points at what the timing is when you look down from the top of the engine bay. The best way I've found to see your mark, is to use a white or yellow grease marker and put a line on the balancer where the particular degrees you want to set it on.
The timing marks should be on the driver's side of the car down by the harmonic balancer on a small plate. theres usually a "pointer" on the drivers side. its attached with two of the front cover bolts. When you look down at your Harmonic balancer there should be something about it that you see that looks kinda like saw teeth with numbers in the gaps. The zero or line whichever year you have should be on the Harmonic balancer.
It is on the harmonic balancer. It will have numbers from -10 to 0 then up to 40(?). Two bolts attached to the block hold a pointer to the numbers on the harmonic balancer. Also this engine has a plug with a black end called the spout it is usually close to the distributor this has to be unplugged to set the timing correctly.This being unplugged puts the engine at base timing. Take care
