Turbo issues troubleshooting
Hey all,
I just finished installing and tuning my turbo FRS. Ran great for about a week, but then noticed some oil smoke coming out the exhaust pipe in city driving, out of boost. It usually happens on low load in 4th or 5th around 2500 to 3000 rpm after its warm. It doesn't happen in boost that I can see, or on the freeway.
My first thought was turbo seals. I took the exhaust outlet flange off and saw no signs of oil on the o2 sensor, or on the turbine fins. Intake inlet side looks fine as well. No shaft play at all, spins freely very nicely.
No oil in the throttle body at all.
Never had a single issue before the turbo was installed. Oil is clean and clear, car still runs great, just that issue. It stops smoking while idle, or higher RPMs from what it seems.
I am about to completely pull the turbo off and check the manfold, but right now I am stumped.
