okay, so I did a compression test on my 2002 s2000, she’s got about 150k on the clock, so I wanted to do a compression test (I just bought the car not that long ago) so I drove the S2 to auto zone and rented a compression tester. When I got back home the car was warmed up and so I started testing the comp. my numbers were (cyl. 1-60 cyl. 2-55 cyl. 3-60 cyl. 4-65) and I did the test 3 different times and the numbers stayed the same. I also poured a little bit of oil in my combustion chamber so see if it was my piston rings and the number stayed the same as well. I have noticed a power loss since I’ve gotten the car but not enough for my engine to be reading such low numbers. I feel like the car wouldn’t run right if the comp was that low. I also have a ticking in my head that I’m pretty sure is my valves but i don’t know if valves could cause low comp! Mahalo
