I performed a dry/wet compression test. Here are the PSI measures:
Left | Right
---------------------
Dry | 105 | 100
---------------------
Wet | 155 | 155
The wet test was performed by adding about 3-Tablespoons of motor oil into the spark plug holes just prior to connecting the compression tester.
Based on other threads and some research, the rings are bad and need to be replaced. Of course, other things may need to be done as well, but I am hopeful that this means that the valves are OK and may not require replacement.
