today we did a compression test on our cars
and heres the result

fastpace
1993 s13 fb
84,xxx miles
#1 cyl = 185 psi
#2 cyl = 187 psi
#3 cyl = 187 psi
#4 cyl = 189 psi
this motor is ready for ka-t

me
1991 s13 coupe
163,xxx miles
#1 cyl = 185 psi
#2 cyl = 190 psi
#3 cyl = 190 psi
#4 cyl = 187 psi
i noticed some oil in the spark plug chamber on cylinder # 2, 3, and 4
im not sure where it came from. the exhaust pours out white smokes at start up.. but not anymore after a while
im guessing that it might be leaking valveseals or a slight piston ring leak but oh well..
in conclusion.. this motor might be replaced with lower mielage KA.. then turbo

but yea.. im still not sure where the oil came from.. it was quite an amount of oil in there...

crude picture yes, but those are the vc gasket and sparkplug gasket in the middle, just pic up a new one, they sometimes come as one piece, or sometimes as 2.

hope thats where u meant

I was thinking about Bbandit's oil problem yesterday, very weird. 240Driver39 how can you fix that problem with the spark plug well gasket?
