I have asked my mechanic to change the PCV valve when I have a tune-up. He keeps telling me that it isn't necessary. I have also asked him to check the emission hoses and replace them some look old and inflexible. Now I am having performance and idle problems with the car and the air filter is full of oil. Did this ruin the motor or is there a hope of recovery?
