I have a 91 Civic LX with 187,000 miles on the original engine. I've discovered the poor performance is due to low compression in all 4 cylinders, 1-135, 2-141, 3-139, 4-143. I believe it's the rings. My question is can i, or is it possible, to replace the stock rings only or do I have to completely rebuild the engine?
