Blue smoke is a sign that oil is being burnt in your vehicle's combustion chambers. This could be a blown head gasket or a bad oil cooler and a failing output shaft seal on the turbo. So let's rule one the possibilities out. Here are a couple of links that either one will confirm or dismiss that your vehicle has a blown head gasket:

This is most likely caused by a head gasket issue.

We need to test the head gasket to be sure. Here is some info that will explain this in more detail. Let me know what you find. There are a few more possible causes but head gasket is the most likely cause.
