Bad oil leak-timing belt cover

I don't know how to do a compression check. Here is what it sounds like:

If the car was running within that past few days compression should not be an issue. I was thinking more like throttle, MAF or idle control valve.

I thought that first, but I checked it has strong spark. I have noticed as I messed with it that it takes three complete revs for the crank to bring the cams back to manufactures mark, so it appears that I could be off 1/3 or 2/3 on the timing.
This is what I am going to do: Pull the plug from cylinder #1 and insert a 12" piece of tube, then turn the crank till I find TDC, check the marks, and then do it twice more for the cycle. I must have it off by 1/3 or 2/3 but since this is an interference engine, I would think it would have given some indication of internal parts contact.

I found TDC on Cyl 1, and it did not line up with the timing mark on the crankshaft pulley. I removed a few more parts and am able to see the crank timing mark on the block and the area where the crank should be notched. It is not. I rotated it through tooth by tooth and took pics if looked possible that it was notched. It isn't notched at all.
What this means is that I have to assume the marks on the crank pulley are good and that I had it all aligned correctly. Now what?
(the pic is at the mark on the pulley)

There is some kind of mark on the crank. Either a knotch in the valley or one knotch of the two peaks on either side of the valley that TDC. When you found the piston all the way up, where was the crankshaft marks near the cover? Did you find those marks?
If you have spark, and fuel pressure, you have an air problem. Maybe your MAF is bad.

I just read back through this post and it seems that you were moving the crank without the belt on. That's not good. The only time I have ever turned the crank is when the belt was on and the crank and cams all turned together.
I'm not sure if you can hear valves break over the sound of the starter. Also, I have never heard anyone ever say they could hear stuff happen when they broke their valves with a bad timing belt.
Maybe you can find a scope with a light on it to look into the head through the spark plug holes.
