I got the following numbers on a 96 850 Turbo motor today and I wonder if anyone can shead some light on what they mean and why they are the way they are. For the leakdown test I put 75 psi into the each cylinder and you can see how many psi it held right next to the listing. All of the numbers are more than the typical 5%. Then when you run the compression test the numbers seem to be higher or better on the ones that have the most leakdown.
On the chart below that I have listed how the cylinders rank in each of the two tests.

To say the least I am very puzzled at why these numbers are where they are. I am looking for any guidance on this issue. Thanks for the help guys.

CYL. Leak Down Comp.
Cyl. 1) 75 -> 57.5 psi --- 145 psi
Cyl. 2) 75 -> 63.5 psi --- 151 psi
Cyl. 3) 75 -> 50.0 psi --- 160 psi
Cyl. 4) 75 -> 67.5 psi --- 150 psi
Cyl. 5) 75 -> 59.0 psi --- 155 psi

Cylinder rank comparison
Cyl. | L.D. |Comp.
-#1-----4------5
-#2-----2------3
-#3-----5------1
-#4-----1------4
-#5-----3------2

If this car has a mileage on it commensurate with its age (like somewhat over 100 K) and you are doing the test with a warm engine and you are using a normal grade of oil, I would just keep driving and maintaining the car as you have. The numbers aren't very uneven for a used engine. At my age I can no longer run 5 miles in 35 minutes but who cares? You can't run time backwards. Good luck.

I'm no professional mechanic but your compression numbers look pretty good to me although the #1 is maybe marginal. I've never done a leakdown test but I would assume, maybe incorrectly, that the results would somewhat depend on where the piston was in the cylinder. Most engines don't wear evenly and the rings may not seal the same at different positions of the piston stroke. So, if you didn't do it allready, to get a good comparison you may have to ensure that each piston was at the same point in the stroke when the cylinder is pressurized.
