Problem seems to be solved. Took it for a spin and kept smoking. Decided to take it all into bits to see what is all fooked. Started with intercooler and a hell lot of oil came out. Bit thinner then i expect it to be so maybe with coolant. As i still had an exhaust full of oil and shit i decided to go a different road. Clearly there has been a big turbo failure else IC would be clean. Gave sb a call to borrow a exhaust manifold of a std 1.6 and exhaust. Build it all up again and ran with good oil pressure and no smoke 1dd13 probably first turbo filled IC and second (which wasn't the most beautiful one) gave oil pressure issues. Seems to be i had two bitchy turbo's. So one is being rebuild now and then i am probably fine with this car again.

Also today i heard sb that also has seen white smoke from a ic filled with oil. This case was on a truck. Maybe due to it being mixed very fine with air color changes?

Thanks all for sharing thoughts and helping me forward!
