Q: What causes heavy blue smoke from the tail pipe, and rattling from supercharger? on 2002 Nissan Frontier

When i start the engine there is a loud rattling sound coming from the supercharger. I also seem to be using excessive engine oil, will this cause damage to the engine if driven this way? How can i resolve this problem? I have also received codes showing O2 sensor, knock sensor and crankshaft position sensor, do all these sensors need to replaced all at once?
