I have a 2013 Cruze Eco 1.4l with 93000 miles on it. Recently I noticed it began running rough on initial startup, but after about 15 seconds it would level out and run just fine. Well in the last 2 weeks its been getting significantly worse so I decided to take a look into solving the problem and would like some feedback from yall before I dig too deep into this thing.
First, knowing I've had ignition coil problems in the past I figured I would pull the plugs. To my surprise they were covered in oil! I then checked the pipe leading to the intake and it also had a good coating of oil, though I would not classify it as totally excessive. I didnt have much time to dig too deep into it that night so I cleaned the plugs and backed it out of the garage.
The next morning when I fired it up I noticed it was running rough again, so I popped the hood and noticed a a decent bit of smoke coming from the turbo and could actually see oil dripping onto the cat and burning off. It looks like it is coming from around the flange but its hard for me to really see exactly where it is coming from as it burns off so quick.
I know of the PCV issues these cars have and am not sure if this would cause the excess oil through the turbo that I am getting. I did check crankcase pressure and it appeared to be around -16in H20 which I believe is correct. With that being said I do not believe it is a PCV issue but before pulling the turbo to inspect further what are some of yalls opinions on this matter?
Symptoms
rough idle on initial startup
Oil covered spark plugs
Oil dripping from turbo onto catalytic converter on initial startup but smoke dissipates after 30 seconds
-16 inchesH20 crankcase pressure
-no CEL or engine codes
What do you think? turbo seals? or clogged turbo oil drain tube? Ill start digging into this more next week, but before I start pulling this apart I wanted to get some expert feedback. Has anyone else seen symptoms like this and what was the final diagnosis.
