So what is true "good" compression? Anyone find out? Do they have that compression tool at AutoZone also? I'll have to check.

the klze should be 210psi, the k8 should be 195psi, and the b6 should be 185psi. the limits of tolerance are +/- 10% for each cylinder and you have to make sure that there is not more than 30psi difference between any 2 cylinders.

That does that do if it is?

probably just build up on the valves not letting them seal correctly....

As far as I know a compreesion test s/b done with a warm engine, plugs out, to get optimum results. You might find that your psi difference between cylinders is less with a warm engine. sounds like good numbers to me anyways. Since you havent started your engine up, you may have a little more or less oil in some of your cylinders.
