OK, I bit the bullet and took a running saw to my Catalina 27 interior to gain access to the front three valves.
Finally I will be able to get in and change the three remaining springs and get to the bottom of the elusive mystery sound.
After eliminating drive train, and other hypotheses, I am convinced that the valves are making the noise.
So, as you can see, I removed the engine door frame, located a good cut line, and let 'er rip.
The result is great access without much penalty at all. Once the cut piece is re-mounted it will be difficult to tell it was removed.
Now, onto the valve project...
