Hello.
I have a 2013 chevy equinox ltz 2.4 ecotech engine flex fuel. my issue is i have an excessive amount of white smoke coming out the tailpipe that smells like burning oil and it hesitates and stalls when hitting the gas. also there is oil coming out of the air intake box and pcv valve. I cleaned out the exhaust manifold orifice I replaced the catalytic converter the 2 02 sensors cleaned out the maf sensor and changed the oil. I use 5w-30 with dexos. It is now smoking like a indian chief smoking a pipe on a sunday evening as soon as i start it which smells like burning oil i ruled out head gasket because the smoke did not smell sweet. there are no codes no check engine light and no oil leaks. im leaning on worn piston rings or bad air intake manifold. what are your thoughts? thank you in advanced.
Sounds like the engine is worn out. You may want to do a compression and/or a leakdown test, but those engines are well known for oil burning and mechanical failure even at low mileage. (Though you did not state mileage.)
