Turbo seals toast?
I have a 16g turbo on a d16a1 engine. The car smokes blue quite bad. Il will try to explain it as well as I can.
When I first start the car for thwe forst 30 seconds or so I hardly get any smoke.
Once it runs for a bit the smoke begins. It does it pretty bad on idle and boost. Once the engine warms up it will smoke when taking off and under high revs and boost, also a bit under decelration. Soemtimes the smoke is blue, other times its almost a grayish steam.
The turbo has in and out play and I pulled the downpipe off and it is kind of wet and tacky. My question is, how badly can a car smoke with blown turbo seals. At times it smokes so bad it is enough to blind the person behind me.

Re: (iROCKtheSOHC)
It turned out to be the turbo seals.
If it were piston rings, it would smoke all the time.
If it were valve seals, it would smoke when first started up.
The car, however, doesnt smoke once fired up. It really starts to puff only a minute or so after running. I am guessing because it takes time for the EGTS to get hot enough to start burning the oil that blew past the turbo seals when it was last ran. Also, it doesnt burn the oil, it steams it sort of. When it comes out of the tailpipe its almost a bluish white smoke that seems like vapour or steam.
The smoke from downshifiting could possibly be the oil in the intake manifold getting sucked through the engine under vacuum. It would smoke the worst when accelerating after engine braking, this I assume is because of the oil in the charge pipe or most likley the oil pressure once again blew oil past the seals and it gets burned off once the EGTS raise up.
I replaced the seals with a different USED set and its ALOT better now, its still taking time to burn off all the oil in the DP and charge pipes, but I am going to try a restrictor next to further stop the smoke. If that doesnt work, I am moving on to a new or rebuilt turbo once this turbo kicks the bucket.
