so i have a 1991 integra with 215000 miles and it runes perfectly except the exhaust fumes smell like its burning straight oil and the oil light occasionally will flicker(this only happens once in a while)but what bothers me is the exhaust fumes are extremely strong and almost make you sick if you have the windows down. i recently changed the oil but that was around 3 weeks ago. any clue on what i should look at?
EDIT:apparently occassionally when i shift the car will blow out smoke. i heard from a friend so as for the color im not sure.
