I have taken the whole thing apart at least 2 times. I have the JD tech manual and I am using a homemade tool. Flat plate with 4 screws holding the valves on their seat, just like in the book. I'm also using a dial indicator to measure the play. In my opinion, I don't think I did anything wrong. The cams are right side up,pointing in the right direction and on the right side. I compared two shop manuals to make sure.

Even if the valves would be a little off,(which I don't think they are), shouldn't there be even a little oil coming out of the coupler?

 I didn't do an air leak test. I should probably try that tomorrow. 

If I can't find the problem tomorrow, it's going to get the sledge hammer fix.

I looked for cracks in the housing, but I can't find any. 

Why is it that sometimes it works and other times it doesn't???????

Wife says I look a little balder tonight.LOL
