The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

2003 Chevrolet Monte Carlo Reviews
Love my 2003 SS! 611,200km and still running! Just changed my first water pump and alternator in it this winter!
Overall this car is great. I live in the Midwest which means I must handle extreme weather--cold or hot. This car handles very well on ice, however, it doesn't take much to get this car stuck in snow since it rides so low to the ground. For some reason, the radio facing gets abnormally hot to the touch. One major headache has been the breaks specifically the rotors. I've had to rotate and replace the rotors multiple times.
I have been pretty rough on this car but it has served me well. The only issues I've had are with the oxygen sensors and the catalytic converter. Both have had to be replaced multiple times. Other than that I have 132k miles on this baby and she still has some get up and go.
