SINGLE EXHAUST VACUUM CHECKING
If you are like me, you test all the valve to seats seal with a vacuum test. It’s not possible when you have a single exhaust system. What I use is plumbers’ putty on the valves of the chambers not being tested to assure a good seal. It also doubles as a way to find any existing leaks.
