[QUOTE="2012Equinox2.4Turbo, post: 21162, member: 7598"] There are some Youtube videos claiming the orifice on the intake manifold is the problem. It's not. Ultimately, GM pushed the compression higher on the LAF and LEA Ecotec than any previous NA version of this engine. The oil ring failure typically causes oil evaporation instead of burning. My 2.4 always ran great and never smoked, even though it used a lot of oil. You can try 20/50 syntheic oil and see how it goes (thicker oil). That slowed things down for me. Another thing to try I posted here.
