I have a 2000 B18C5 in my 93 Civic H/B and im blowing smoke. I have I/H/E and VAFC on it. It didnt start smoking until i put the JDM 4 to 1 header from DC Sports. So at first i thought it was the header. But after a week that assumption was pretty much tossed out the window. Now the smoke is of a bluish tint which i know is supposed to mean smoke. So i checked my compression and it was perfect in all 4 cylinders at 135psi (well it was a little on the high side at 143psi) So i know its not my rings. So then what could it be. How would i be burning oil? Oh and the motor only as 14k miles on it. Any input would be greatly appreciated.

 

your psi should be around the 180-220 mark. Some are even getting 240. Blue smoke means oil.
IT sounds to me like the rings. or head gasket.

Well i checked the local Acura dealership specs manual and it said 135psi plus or minus 28 psi so 107 low and 163 high and i also check the head gasket and its ok. so i still am not sure.

 

Just curious How did you check the head gasket?

Don't ya have to take the head off the motor to see the whole gasket???
