I searched..........

So I did a compression test on my sr20det and it was 140 all the way across. I know 150 is the good range, so is 140 all the way across ok??? I did it at a little below normal operating tempature(Does this effect the readings if not at exact operating temp.???) and yes I had it at WOT. Does it just mean my piston rings are wearing? Thanks for any help.

its fine. as long as it is consistant. also there are a lot of threads like this one. if you searched you would also know that some people have 120 all across with no problems

I did search, none of the posts i found said anything about being below 150 and consistant. Well now that i know that people with 120 across are still good, then im happy. Thanks man
