Many turbo setups use oil drains that are way to small. People don't realize that it has to be at least 1/2" line with a constant downward travel to the pan. If its kinked or too small it will cause excessive pressure in the turbo and blow out the seals. Since you know so little about it your thread needs to be where to take it to get it looked at in the time frame you have to work with. No one is going to be able to fix your car on a forum if you know nothing about it.
