As you've seen in the title, my cruze is blowing a ton of smoke. It is a 2012 Chevy Cruze Eco 6mt 1.4t with 49K on the clock. It has a catless exhaust, trifecta tune, and a rear muffler delete. Under acceleration there is a nice long plume of smoke coming out of the exhaust. I will post a video so you guys have a better idea of what color it is and maybe I can figure out what is going on. Taking it to the dealership is almost not an option since I don't really have a local one, and, the two that are relatively close are absolutely horrible. I don't think it's oil. I used to drive the car really hard, but, only after it was warmed up. I bought the car used with 28K on the clock. I don't really drive it hard anymore. It doesn't blow smoke on high revs in first gear. Only a tad in second gear. But, in sixth gear the car smokes like crazy. I haven't examined all of the gears, but, it seems at highway speeds the car smokes more, not necessarily related to rpms. I will try and post a video of the smoke soon. Any help is greatly appreciated. I'll be monitoring this thread closely. I'm fairly sure it's not piston rings as I ran a compression test last week and it checked out. ~190 on all 4 cylinders. I have a boost gauge and it seems to build a ton of boost really fast in sixth gear on the highway. Could this just be something simple or a turbo or a seal somewhere? Thanks!
