    Heavy white smoke

    Hi guys new to this group. Just installes a new turbo for my brother in law on his 2013 cruze. They never changed oil for 4 years needless to say the oil feed to the turbo was clogged. I dropped pan and valvecover and cleaned out all the sludge and at first startup it ran perfect. Now with about 1 hour of run time. I have p0496 code and heavy white smoke. I pulled turbo off to see if seals went out in it and i had lots of oill coming out exhaust ports. Any ideas on how this oil is pushing out the exhaust? Thanks

    Welcome Aboard!

    I have always thought that white smoke means coolant in the cylinders. How is the coolant level?

    P0496 is an evap code. I wouldn't think that it would be related to your white smoke.. Is the smoke white or light blue?

    As far as oil out the exhaust ports go, the rings may have stuck and it's pushing oil past the pistons. There's no telling what you'll run into when working on a sludge bomb. It'll probably start knocking next as you've disturbed the sludge and a lot of it will end up in the oil pick up tube screen.
