Bad ring. make sure your pcv valve and breather tube are working. lack of oil changes can cause ring not to seat. flush engine with gm top engine cleaner. may help release rings. run engine about 25 miles then change oil,
SOURCE: engine blowing oil from oil filler cap
I had the same problem. I changed the pcv valve and checked the hose. It still did the same thing. Then I checked the metal tubing that the hose connects to and found it was full of hardened gunk. I sprayed PB Blaster into the tube let it soak for awhile. Then took an old choke cable, put it on a drill and ran it into the tube like a drain snake. It took a while of doing this over and over but eventually got it cleared out. Now, no more oil all over the engine and hood compartment.
SOURCE: motor oil spitting out from the dipstick. No smoke, no blow by.
Have you checked for a PCV valve plugged? Not sure if there is one an that, but would sure look for one. Crankcase ventilation somewhere.

Hello, what color is the smoke? If it's white in color your burning antifreeze. If your burning antifreeze the most common problems are a bad head gasket or cracked head.
If the smoke is blue in color your burning oil. There are many reasons to why you could be burning oil, all of which mean one of three things. You can either rebuild the motor, replace the motor, or drive it with it burning oil and check your oil level periodicaly.
There isn't really anything you can do to check what is the root of your cause with out disassembly of the motor. There is a tall tale sign of a bad head gasket or cracked head and that is your oil will have a milky color and texture to it or your coolant will have an oil slick on the top when you take off the radiator cap. This doesn't always happen with a bad head gasket or cracked head but it is one way to generally tell.
SOURCE: blue or white smoke comes out when i push the gas
It
appears that the oil is being burned by the engine. You may or may not notice the engine doesn't have the
same power as it used to
Possible causes are piston rings, valve seals may be worn, damaged or worn valve guides, PCV valve is faulty. The only one that would be a DIY would be the PCV Valve, all the others should be left to qualified people

Either the heads are cracked, the cylinder walls are cracked, or the head gaskets didn't seal properly. You need to check your catalytic converter/exhaust, there probably is what caused the problem & accounts for why the smoke is coming out of the top of the motor, it can't escape through the exhaust due to the blockage.
good luck,
sometimes a used motor is less expensive than repairing one that is bad & especially if you get a warranty.
