A leak down tester is a gauge set that allows you to pressurize a cylinder and look for leaks. It allows in say 100psi and you see how much it leaks down, say 20psi. Then you would have 20% leakage.

The nice thing about it is you can listen/look for leaks. If there is air coming out the tb you might have a bad intake valve/seat/spring. If you hear air coming out the exhaust you know it is a burnt exhaust valve seat/spring etc. If you take off the radiator cap and see bubbles then probably a headgasket.

A great tool for internal diagnosis, you do however need a decent air compressor.

I bought this el cheapo off ebay. Works well. There are some buy it nows if you dont want to bid. Otherwise I am sure LSE or DB or MAP could do it for you cheap.
