CYLINDER COMPRESSION

1996 Saturn SW2

Engine Mechanical problem
1996 Saturn SW2 4 cyl Front Wheel Drive Automatic 107000 miles

I have oil on the #1 cylinder spark plug. I performed a compression test and the results were 200, 205, 220 and 225 psi. Isn't this too high? What would this mean?

That is some serious compression any chance too much oil in engine? If not oil rings bad leaving oil in cylinder acting like za seal bumping up compression. Any smoke from tail pipe?

Oil level is fine. Blue smoke when starting for the first time of the day. Runs rough for about 15 seconds and then seems fine.
