Just did a compression test for my 95 b18c1. it came out as 199-190-195-170. I'm not really sure if that 170 is normal. let me know what you guys think.

 

B18C1 compression is...
Standard 270psi
Minimum 140psi
Max Vari 28psi

Your 170psi cylinder is more then 28, [29] psi off the 199psi cylinder.

Now before you go and pull the head for a valve job, do a valve lash adjustment, you may just have a "tight" valve, then redo the compression test both dry and wet, if psi increases significantly with the wet test, you need now rings. 94

 

do a leakdown test. it'll tell you where the compression is going.

 

Fcm hit the nail on the head
