I went through a similar issue with a Ztec. It turned out it was the hose to the PCV. I had also sprayed all the hoses but this one fails underneath were you can't see it and you can't spray in that area. We finally took it to a shop with "smoke test" equipment and they found it in a couple minutes. This equipment puts smoke into the engine and it is easy to see where the leaks are.
