This is a non camaro question, but my 1989 pontiac grand am, Quad 4 motor is spitting oil out of the tail pipe. It also smokes white until it has been driven from about 10 miles. I checked for antifreeze on the dipstick, and checked inside the radiator, nothing out of the ordinary yet. Any Ideas? Thanks.

If your idle mixture is too rich what you see as oil could be black soot and condensation.

Quad 4's are bad about blowing the head gasket between the 2 center cylinders...not quite as bad as the dodge 2.2's but still pretty bad. Run a compression test...that will tell you real quick whether its the head gasket or not. If it really is spitting raw oil, then you either have a broke ring or busted piston. But, like dennis said, it could just be water or condensation mixed with exhaust soot. If the O2 sensor has been bad for a while, the exhaust system could have a lot of soot built up in it.

Thanks for the great advice. I looked over closely, it is just sotty condensation. I need to buy a compression tester to find out if its a head gasket. Working on these newer cars are a real pain the butt, with all the different sensors. I pulled the plugs and they were a white ashy color. I gave the car a complete tune up, including O2 sensor and now, it cut down on the smoke, but after it warms up, it loses all power after 2500 RPMs?!? My Grand am and *7 Iroc are driving me crazy. Thanks again for your responses.
