I recently replaced p/s and a/c belts long over due. Now I have a light high pitch noise with rhythmic low (almost like a growl) pitch kind of knock. I looked at the belts and a/c belt keeps rising over the edge of the a/c pulley. I checked to see if anything is lined up and noticed the crank pulley is out further than the compressor pulley by 1/8 to maybe 1/4 of an inch. A few more turns and the bolt to crank pulley would have been completely off.
I'm going to loosen p/s and a/c belts and tighten the crank pulley but my question is does it sound like I'm going to have to reset the timing? It should set itself automatically correct?

No. The pulley mounts on the crankshaft with a key to position it, so the rotational position of the pulley on the crankshaft has not changed.

That's right I totally forgot about the key. I had taken the valves off and them redone a year ago and put everything back together. I spent a week and a half on the timing chain and camshaft brackets I should have remembered the key being the"key" (no pun intended) factor to the timing not having to be reset
Thanks for responding so quickly it is greatly appreciated.
