Default Low Compression

What would cause a motor to loose compression so bad? Compressions are 26 25 25 50. What would be the causes, and is it fixable.

Do a leak down test to further determine what it might be. Those are pretty low numbers, it could be a few things. Do the leak down first.

Its not my R motor, its a JDM B16. So obviously its not under warranty. The motor was running fine, then my friend parked it for about 2 months, then tried to start it and couldn't. Thats when the comp test was done.

I would say to re-do the test with a new device!!! Those numbers are not right at all for that motor!!! I have a feeling that maybe it was due to a faulty Compression tester.
