I am going to replace the PCV valve on the 98 camry in my sig. We only need this vehicle to last another 4 or 5 years max, if that matters. Local dealer is across town. Wondering how important it is, to get an OEM PCV valve. Its not the money (although they do charge more) so much as the inconvenience of having to go there twice, once to order and the second time to pick up the part. Are there good aftermarket suppliers I can count on, or should I just bite the bullet and buy from my dealer?
