Distributor position question
So, if I find TDC(with advance connector unplugged), and the rotor IS tween #8 & 1 wires, and the crankshaft pulley marker is nowhere in sight, or at least a good ways away, does this indicate that the dist might have gottten turned?
Or
Does the fact that upon finding TDC, and rotor points tween 8&1 wires tell me the dist is in the CORRECT spot?
thanks fellas,
Rich

when you turn the motor in the direction of rotation (clockwise if you're in front of it) you watch the intake valve of number 1 come up, go down, and then bring the harmonic balancer mark to zero on the timing tab. Remember, it is a 4 cycle engine that take 720 degrees to complete one cycle. You can also put a finger over the spark plug hole and feel for the compression stroke. The mark on the harmonic balancer will always be tdc of 1, or 6 depend on where in the 720 it is. This assumes balancer is good.
At this point #1 is wherever the rotor points. You can adjust it where you want if you like, but will have to move oil pump shaft keyway to achieve what you want.

It may be right
If the rotor goes past 1 to almost 8 the pointer will not be on the mark it will be a bit past as you say. Drop it in see where the rotor points
Remember the dist only turns half the crank speed so if the rotor moves a little the balancer will move away that much further from the pointer

If you have TDC set #1 cylinder and the mark on the crankshaft pulley ( harmonic balancer ) is nowhere in sight or not positioned right your harmonic balancer has sliped. The harmonic balancer is a 2 piece unit and with age they spin so you lose the timing mark. You need to replace it. You could mark the new TDC point using zero on the timing tab and a line on the harmonic balancer and set the timing, but the inner and outer parts of the balancer will continue to slip. They are held together with a piece of rubber which wears out over time. If the harmonic balancer moves inward to much it can cause damage to the timing chain cover. Make sure to install a new timing chain cover crankshaft seal with the new balancer.

make sure the balancer is ok. also make sure your balancer is the correct one for your car. happened to me. my balancer was bad. so I get a new one on ebay. the problem is that there is 2 kind of balancer for my car the only diferance is where de cero mark is. so may mark on the new balancer was off. give me a lot of problem into I discover this problem.

Or if you are referring to the rotor in the distributor it is 180 degrees off.
