The oil pump is driven off the cam gear on the bottom of the dist. The pump just needs to pump and hold the correct oil pressure for the engine. Hope this helps.

Auto Talk site online type in question start with oil pan removal.also ck youtube videos.

First thing,don't let the manufacture tell you that you can 5000 to 6000 mile without an oil change.Next thing they want you to use oil that is much too thin.They don't want the engine to last too long because they can't sell you a new car that often.City driving you need to change your oil at least every 3000 mile and highway every 4000 mile.The biggest problem is having you oil changed at a quick change that uses BULK oil.If they don't offer oil from a jug,next time bring you own oil if you have to.Use 10w30 in the winter months and 10w40 in the Summer.It don't hurt to put in a can of STP after each change.

That could be from not having any oil pressure "oil pump failure, clogged filter, etc" or from a faulty oil pressure sending unit. More tests would need to be performed but is it really an oil pressure light or is it the change oil light. More info would be needed

WELL NO OIL LEAKS.WARRANTY MIGHT COVER IT BUT YOU NEED TO SHOW ALL OIL CHANGE RECEIPTS.ALSO YOU HAVE TO USE GM MOTOR OIL LIKE 5W - 30 VALVOLINE USE GM OIL FILTERS.THEY WILL CHECK TO MAKE SURE YOU BEEN KEEPING UP WITH SERVICE MAINTENANCE AND SERVICE SCHEDULES.CHECK YOUR OIL LEVEL ON DIP STICK SHOULD BE AT FULL MARK LINE. THE CHEVY COBALT LS LT LTZ 2.2 ENGINE HOLDS 5.0 QUARTS OF OIL WITH NEW FILTER AND CHEVY COBALT SS SC HOLDS 6.0 QUARTS WITH NEW FILTER.IF OIL LEVEL LOOK OKAY.CHECK ON INTERNET FOR ANY RECALLS OR ANY TROUBLE WITH EARLY OIL PUMP FAILURE.

Oil pressure is created by the oil pump, the main bearings and cam bearings. If these bearing are worn, excessive clearance, you will lose oil pressure. The rattling could be a rod bearing or wrist pin. You could try installing a "wet gauge" and check the oil pressure against the OEM specs, at different RPMS.

The best thing to do is run a trouble code check on it.
Other than that check for a vaccum leak, the EGR valve, or the idle air control valve.
