What kinds of compression tests are there? I've seen the manual ones where you put a gauge where the spark plug goes and you turn the motor over and it gives you a reading.
The reason I ask is because the people that are working on my truck said they did a compression test where they pressurized the cylinders and left them over night and 3 of the 4 had lost all their pressure by morning. To me, this makes no sense. Wouldnt it be impossible to for a cylinder to hold pressure over night like that and what the heck kind of test would you call that?
