How does a cylinder leak down tester work?

Also question is, what does a cylinder leak down test tell you?
It's called a cylinder leak-down test. A leak-down test can tell you if the loss of compression is due to things like worn rings, burned or stuck open valves (intake or exhaust) or a leaking head gasket. You read inlet shop air pressure on one gauge and read the percentage of cylinder leakage on the other.
Furthermore, how much does a leak down test cost? Use compressed air to blow away any debris from around the plugs first, so that it doesn't get into the cylinders. We paid $40 for our leak-down tester; prices range up to $300 or so.
Similarly, you may ask, can you do a leak down test with a compression tester?
If you stopped reading right now, a novice might choose a compression tester. You can't use a leak-down tester without an air compressor or nitrogen tank. To use a leak-down tester, you remove the spark plugs as above and rotate the engine until the piston is at top dead center for the cylinder you are testing.
How do I know if my valve seals are leaking?
When valve seals begin to wear or fail they produce some obvious and unique symptoms.
- Cold Engine. One of the most noticeable signs of worn or cracked valve stem seals will be just after a cold engine start.
- Idle and Stop and Go Driving.
- Off-Throttle Braking.
- Oil Consumption.
- Excessive Smoke.
