I have 1997 Cavalier that has a little motor work done to it. Its not completely stock. Its a circle track car. I have been replacing vavle seals in it every three races. I just noticed the pcv valve is missing. I know that is the cause of all my dirty oil and smoking problems. Now, if I put the pcv valve back in is it gonna kill any horsepower or hurt my engine?
put it back in and make it run better i assume you have a 2.2L then
