Compression Test
Hello, all.
I did a compression test on my 1998 Cherokee XJ today. My XJ has 220,300 miles. I've attached the results so you can take a look. Can anyone help me interpret these numbers?
Thank you.

That ain't good. I see two possible explanations for those readings:
By the way, there are a number of free programs that will easily rotate pictures for you. I use both Xnview and Photofiltre.
- You have done the compression tests incorrectly.
- Your engine is shot. (Rings, or possibly valves.)
