I had a compression test done on my car 94 JDM H22a swap when it was cold. Basically it sat over night until about 4 pm. Then did the test.
I was wondering would the results be that far off depending on cold or normal operating temps?

Cause when it was done the guy said it was 250 across the board, but then I get on here today and read some old posts and it looks to be a bit high. I am wondering if the test was done wrong or if the cold motor has a huge factor on correct numbers?

thanks

250 across the board? god damn those are some crazy *** high numbers

he eithre lied to you, or has no idea how to do a compression test.

 

Yeah I am gonna have to buy a compression tester and do it myself. I thought it was alittle weird. So I should be doing this at normal operating temp?

thanks

 

Yesh, warm it up, throttle open, crank away. It's nice to unplug the injectors too.

 

ok

thanks again.
