Hi all, have a stock standard 93 eb falcon 6 cyl. In psi, what should the compression be? My readings got between 180 - 190 psi on all cylinders. Any advice / help muchly appreciated. Mick

As a rough guide, the lowest reading cylinder should be no less than 75% of the highest.

Redone the test and got the same results. Cyl 1- 190 psi. Cyl 2- 180 psi. Cyl 3- 190 psi. Cyl 4- 180 psi. Cyl 5- 180 psi. Cyl 6- 190 psi. Do these figures sound right?
