I posted this also down in shop forum, so feel free to answer either place. Anyway the first 1500 miles I had this car (had 119k miles when I bought it) it used quart oil every 500 miles. Think mostly leak from rear main or fuel pump flange as plugs didnt look like it was burning oil. Oil consumsion then greatly increased and oil slick under car. Replaced rear main. No change. Used 6 quart in 750 miles and oil all over engine and bay. Figured passenger side driveshaft was tossing oil around that leaked from engine. Epoxied around mechanical fuel pump flange and oil consumption dropped to 3 quart in next 750 miles. Happened to open air cleaner and air filter soaked with lot oil in air filter can. Okay has to be crankcase oil up through pcv fresh air intake hose. I am not just absolutely positive but must be as no other way that much oil would get into air cleaner. Pcv valve is functioning properly. Been looking on internet and couple posts indicating higher mile Festivas have pcv problem. Couple people mentioned installing larger pcv valves and that this helped. Didnt mention oil use to this extent though. Any other Festiva owners out there run into this? How did you solve it short of engine rebuild?
