Looks like its down 30-25-25-25-25-25. The first one is probably either rings, or exahust valves. I *think* that the loss of the 25 psi per cyl. is normal for 121K, basic wear. Low compression is usually, rings, or valves. . . not much else. Pistons are probably fine, as is the block.

Best,

I just had a compression test done on a 91 m5 with 121,340 miles. The numbers were 145-150-150-150-155-155. Are these good numbers to look at? I realize this is a M3 board but this board always has good responses
Thanks in advance
Brent
