    Yes we vented the sump tank for the turbo's into the breather as well. Open breather off PCV valve just doesn't work on the VQ motor. I had a small amount of consumption but not much (a little oil makes a lot of smoke). I don't remember the size of the lines off-hand. They weren't huge. The turbo's gravity fed to a tank under the trans/motor then a pump pumped it back up to the pan. I had a lot of oil when you let off gas after pulls (was like a mosquito fogger). After the catch-can there was zero oil. If you have oil at other times it may be more than a small amount of blow-by.

    Hey Tom,

    Thanks for the reply. The thing is, along with smoke I'm getting oil consumption as well. Did you vent your sum tank? I have an open breather set up for the pcv. Also, what size line did you use to scavenge oil? Where was your pump located?

    Hey George.
    I had exact same issue on my sound performance setup (which is very close to SFR). Once we put a catch can setup on the car the problem went away instantly. SP made a custom Catch can that was quite large and mounted above the radiator. We also vented both valve covers not just one bank.

    Hope that helps.

    I have been all over the web researching issues with low mount twin turbo setup. I found you from the G community and finally here. My question is, i have an SFR twin turbo kit that mounts low and having smoking issues with the turbos. Smoking happens while boost and while decelerating. Turbos where sent back and check out fine. Engine is freshly built by SFR and a compression and leakdown test was checked in good health. Along with smoke obviously comes oil consumption. How did you fix your issue? I am going crazy trying to find a solution. I really appreciate all the knowledge you can give me based on your experience.
