I don't know the cobalt personally but if it is the V8, they may have a neck that just use an O ring around the metal sleeve, otherwise it is a leaking rocker cover gasket
Not sure I follow you on the part about it getting worse when you accelerate, but generally speaking an engine burns oil when the rings or valve seals are worn.
Due to tight tolerances on Japanese engines the factory most likely recommends 5W30 I on the other hand recommend : If the engine has less than 50,000 miles 10W30. If it has over 50,000 miles on it and isn't burning oil (black smoke) i use 10W40. If it's over 150,000 and is a little sloppy ( burns a little oil) I use 10W40 in the winter and 20W50 in the summer.
I think that could be your valves, or piston rings. when they get old and worn, oil can get past them, and then the oil burns (along with the fuel), making the smoke coming out of your exhaust. I'v has some car which smoked VERY badly, and I tried a additive called "restore" (that have it walmart, and other auto stores for about $6-$7 in a silver can). After about 400-500, it really helped. But I think it will only help if the problem is your piston rings (and not your valves). If the problem is your rings, the "restore" will also make the rings seal better, and it can improve fuel economy while doing do (giving your engine more compression=runs better=uses less fuel. I cant promise it will solve your problem, but IF your rings are the problem, then you would be luck, because that stuff has done miracle cures for me on the past.
hi, the main cause of major oil consumption is due to cylinder wall deterioration. this is caused be bad piston ring sets that tend to chip of tiny pieces of the cylinder walls over a long period of time. this will start to show in engines with high millage. this will also lead to compression loss as well if it is not fixed soon.
To fix this issue within the cylinder walls, they will have to be machined and a new set of piston rings will have to be fitted around each affected piston. this will stop the oil from leaking into the combustion chamber and it will restore the compression rate as well.
Take your vehicle back to your mechanic, and have him perform a DRY, then a WET compression test. Please provide both readings back to me. In the meantime, ask him what it would cost you to him replace the piston rings. This is your problem. The 2 tests will simply verify me thinking.
