Leak-down Test

I decided to check the engine to see what kind of condition its in and if it would need a tear down. We built a leak down tester from some parts my dad had laying around and hollowed out a spark plug to make a fitting (I will do a full write-up on how to build one). Long story short, all the cylinders but one had zero compression. You could pretty much hear the air coming from all the valves, so I decided to take the heads off for a some cleaning.

Home built leak-down tester. Just some simple NPT fitting and gauges. Pretty easy to make, except for hollowing out a spark plug. I will do a writeup on how to put one together in the near future.
