compression

I have a 93 f150 with a 5.8L. I did a compression test because I have oil spraying from the breather and all cyllinders are around 125-130. Is this normal or bad.

Compression is OK.
Replace your PCV valve

I cant find specs anywhere on what the compression range is for that motor. Does anybody know?

I dont know the exact specs without looking, but that is fine. Since the readings are all very close there is no problem there, Id look at the PVC valve.
