Success!!! I removed the lower intake manifold today, pressurized the system once more and confirmed that the leak(s) were coming from the failed O rings at each end of the bypass pipe. After confirming this I then drained the system, removed the thermostat housing on one end and the heater hose fittings at the other end and then removed the pipe. The O rings were flat and very brittle. I will replace the O rings and a few hoses and clamps as, I don't like the way some of them look, out with the old. It's definitely been a process and I'm not done yet, but I feel I made some really good progress today. Yay!!!
