My dad had a air/oil seperator installeld in his pick-up and his caddy. Its run inlune in the PCV line that runs to the throttle body. There is a "filter bowl" that collects the oil that. It seems that they make more power now, and they swear that that your engine burns cleaner and will last longer. Has anyone else herad of this before. I'll try to find the name of the company, and a web site too.
