okay i have a 1991 Honda CRX just a base model. I bought it used with about 157000 miles on it. It was burning wat we thought to be oil so I had the head rebuilt including guides new seats and we replaced the gaskets. Got the head back on still smoked. The color of the smoke btw is hard to tell but is usually blue or white but more often blue. Now I just replaced the PVC valve still burns. Also the plugs aren't wet just have lots of carbon build up so i don't think the rings are bad. The compression is good. My guesses are either the catalytic converter, cracked block, or bad rings. I NEED HELP BAD! any words of advice are greatly appreciated.
Thanx
Bryan
