Hi, you may have a plugged up converter. When a converter plugs up, the exhaust has no where to go but stay in the engine. This will cause the engine to get hot in a short period of time. Do a pressure test on your cooling system. If it holds pressure, this would be a good thing, if not, this means the water is going somewhere. It still could be a sign of a leaking head or intake gasket. I'm willing to bet you may have a leaking intake gasket and your water is entering the head and going out the exhaust causing your tailpipe issue and the water has loosened the carbon in the exhaust system plugging the converter. The engine will loose all kinds of power with a plugged exhaust. If that checks out, check out you MAF (Mass Air Flow) sensor. This tells the computer how much air is entering the engine in which the computer tells the injectors how much fuel to give the engine.

hello your intake gasket is most likely leaking internally into your engine.pretty common problem.the plastic and silicon gaskets get weak over time.

There are no Lifters in the Dual Overhead Cam Motors. Once these 2.4 Liters start Tapping, It is just a Matter of time Before they Stop. I had to Replace one not very long ago for a Customer with the Same Problem. Please Rate my Solution, I need all the Help that I can Get! Thanks!

to look up you car. Lots of recalls. I did not see the oil leak.

SOURCE: OIL PRESSUE LOW

At some point, your engine is registering low oil pressure and warning you the oil pressure is insufficient to lubricate the engine properly.

How does the engine know this? What causes it? Excellent questions. The engine 'knows' this because there is one or more sensors that read the oil pressure all the time. The sensors report to the computer which reports to you. They could be faulty. On the other hand, there could be times when oil pressure IS low. Your oil pump may be mal-functioning. Normally, I would expect the oil pump to either do its job properly or NOT do it properly but not act intermittently. It may warrant being checked by a professional. Another reason for this condition could be the oil itself, though you report you just had it changed. Presumably, whom ever did the change put in the proper oil grade, service and weight, recommended by GM.

Another thought, is this warning seen by you immediately after you start the car? If yes, it is normal for oil to take a second or two to build the proper pressure, particularly in cold weather. Where I am at, it is cold. Oil doesn't like to move when it is cold (like me) so it takes a bit of time to get up pressure (like me).

If this continues, you may want to have this problem looked at by a professional, as I said.
