question about compression tests

ok just did a compresion test on my car and all clinders had 177 I belive +/- 2.5 they where almost identical the +/- is mostly as the gague might have been off, cause they all came to that number, this is good right, and by knowing this what do I know is NOT wrong with my engine :P

Thanks

ps if they all are good that means i do not have to do a "wet"? compresion test, someone told me once that puting oil in the cilinder will tell me more info when doing this test

Your engine appears to be healthy :)
Those are good numbers. All adding a touch of oil does is let you know if your rings are bad. I would only bother doing that if you had a cylinder with low compression.

A leakdown test will tell you even more about the health of your engine.

how you do that ? we got a nice auto shop on base but it is do it your self for the most part

Leakdown test is realtively easy to do ... but you need an air compressor and a leak down tester :)

Basically you are psuhing a preset level of compressed air into the cylinder and measuring how much is leaking out. Let's you know if it is good-n-tight.
