I have a 93 honda civic ex coupe and i just replace the pistons in my JDM B18C with b16 pistons and I replaced piston rings and all that. All new motor basicly. But my question is when will my car stop smoking, I have gone almost 200 miles and I dunno if my piston rings just havent had enough time to seat all the way or what. How many more miles do you think it will take? Or is there something wrong with the rings? thanks guys.
