Performing a compression test.
OK....to tell how the valves are, run a comp test on each cyl 3x. Watch the FIRST JUMP of the needle each time, then the last reading. Write it all down.
If the FIRST JUMPS are low, then it comes on up to, say, 110psi, then the valve is bad. If it is low, and it only maxes at, say, 60psi, then the valve it REALLY burnt, or sticking open some.
After doing all this, do it all over again, but (using an oilsquirt can) squirt some oil (about 1 ounce) into each cyl before testing it.
If the final #s come up alot, then the rings are shot.
