I replaced the piston rings and installed new ones correctly. Upon reassembly I checked to make sure timing was aligned. I am getting spark fuel but no compression over 100 psi. When cylinder head was off it seemed like it had or would have rather very strong compression because while cranking over motor with a ratchet all cylinders would suck my hand down hard when I covered the cylinder with my hand. I have actually checked everything five times; now the first two times revealed leaky valves so I lapped them in and that took care of that problem. Now all I hear is mostly blow by going down not being held by rings and I clocked the rings like they do with race car engines. Marks all line up everything is right except compression. When I said the first two times revealed leaky valves it was with two separate cylinder heads I couldn't get the valves to seat properly on the first head. So I bought a head from the wrecking yard out of a 2006 Corolla and those valves seated better than I thought they would after a thorough lapping job.
