When you had it apart, did you check to see if the valves were sealing? Loosen up the rocker arms so there is no tension on them then fill the ports with gas, paint thinner etc. See if any of the liquid seeps past the valves. I have seen a loose piece of carbon get under a valve and hold it slightly open. Of course a compression check can help verify this if the motor is together. Run a compression test. If it is low, squirt some oil in the spark plug hole and retest. If the compression goes up, you have a ring issue, if the compression stays the same, you have a valve issue.
