I just rebuilt a b18a1 and is fouling the plug on #1 and smoking pretty bad. If its a piston ring would the smoke go away after pulling a hill and wot because it does. If its a valve seal could it act like a piston ring and smoke everytime i accelerate? i know i had trouble installing the valve seals and could've ripped one possibly. after parking the car i pulled the plugs and i can see oil sitting on the piston.
