318 Dis-assemble & Assembled 1st time

This is my first attempt to rebuild a engine. Any engine for that matter.

I am in the process of tearing down the 318 since it is burning oil and lacks all kinds of power. I added a small cam, intake and carb and even gears, but it was obvious that what really was needed was to fix the oil burning and low compression. One of the cylnders registered a 125 psi cranking pressure. The rest where in the 140's to 155 psi. An that was before the abuse I put on it.

Anyways, after teardown, I noticed the entire pass. head covered with oil in the combustion chamber and all plugs oil fouled. The other side looked good.

However all top rings I measured had a gap of .05 or more. Is that correct for a factory ring or are these rings just another sign of abuse and wear?

I have pics of everything that I have disassembled including piston tops and chambers if that helps.

So what caused just one side of the blocjk to burn oil like that and what other measurements should I do to help determine what happened. Or do I just skip this and go right to the rebuild?
