This is the story in short...
The turbo needed a new oil return which when was replaced initially was not done right because it was still leaking. So the mechanics took it off again and fixed it but with instant gasket paste, or some sort of sealing silicone, which I read was a big NO for oil feed and return pipes.
Since then I have been experiencing problems. Stared getting blue smoke in puffs after idling for a while or when starting a hot engine, oil consumption (didn't have it b4), fair bit of oil in the IC pipe.
Now the feed pipe is showing a leak. Could it be that the gasket paste blocked the return pipe and its building up pressure on the feed pipe and exerting pressure on the turbo seals and filling up the IC pipe on one side and the exhaust on the other, hence the mentioned symptoms? Is it possible that is caused problems to the turbo seals now, even if the return pipe is cleared out ?
I didn't realize this until I took pictures of the turbo from underneath and saw the gasket paste, I suspected the behavior on the breather pipes since the one below the crossover pipe was bent and not a lot of room was left for the engine to breathe properly. In the mean time I changed the breather hoses but no improvement.
