Answers :

Try replacing your pcv valve, which means positive,crankcase,ventilation, you will find it on the valve cover closest to front of the car. on the right side of engine[you did not specify which engine size you have] i hate to guess,so, suggest you repost your question with correct engine size,but it's not that hard to find,look for a vacum type hose that connects to one or other side of valve cover.it's a push in cylinder that gives your crankcase positive ventilation. i also suggest you change oil and filter,please purchase a good filter,such as fram,i'm not supposed to advertise for products so please ask your parts dealer for a productive oil filter.the only other two things it may possibly be is a bad oil sending unit which is located above the oil filter,may be unplugged,or bad unit. or may be oil pump going bad-[worst case solution] wish you the best and thank you for choosing fixya.com
