I just used a compression test kit from shucks.

testing for b81b1 obd1

in descending order....

4 - 150psi
3 - 150psi
2 - 150psi
1 - 151psi

they all seem constant. but is that or ??? any replies would help!!!

 

oh and yah i didnt keep the throttle open, and it was about 5 cranks. before i stopped.

 

thats good, as long as they are really close, and 150 sounds good

 

standard is 199 psi, and the minimum acceptable pressure is 135 psi. (from my haynes book)

 

That sounds about right. I did a compression test on my sister's b18b1 motor it came to about 170 for all 4 cylinder. This is with 110,xxx miles on it.
