Someone is giving me a ford or mercury car. About a 1992 +/-. Body/interior good shape..it's been sitting for 1.5 years. He said it was running fine when parked BUT...... It started smoking, and he found about 1/4 inch of oil in the air cleaner. Is this a PCV/emission type problem, or is it more serious. It is a 6 cyl. Sorry about the lack of facts...but I just saw the car briefly yesterday, and am headed over to take a closer look today. Thanks for your help and ideas..
