I just recently purchased a 2006 S2K. The car has approximately 35k miles on it. However, the engine is not the original engine...it probably has somewhere between 70k and 80k miles on it. I have no trouble codes, no history codes, no check engine light, no loss of power, no smoking, no burning oil...etc. The car idles and drives pretty much perfect. However, just out of curiousity...i ran a compression test on the engine and came up with the following results...

Cylinder 1 -- 180
Cylinder 2 -- 220
Cylinder 3 -- 210
Cylinder 4 -- 235

Afterwards, I ran the test again with a different compression tester, and it yielded the same results. Normally I wouldn't be too concerned...but the 180 doesn't sit too well with me. I think Honda calls for no more than a 28% variance between the low and high readings. I was wondering if anyone may be able to point me in the right direction on how to bring up the reading for cylinder one??? I don't have the tester to do a leak down check. However, I am thinking/hoping perhaps a valve adjustment may cure this? To my knowledge, other than oil changes and other small maintenance items, no other maintenance has ever been done to the engine. I'm pretty comfortable performing mechanical repairs and engine related repairs. I'm just not too familiar on diagnostics and such. Any input or pointers would be greatly appreciated!

 

Can't tell anything without a leak down test. Why the motor swap?

 

Had a turbo set up on the original and parted the turbo out as the entire engine assembly.
