Well ive noticed my supercharger is making a grinding noise. Its faint.. But its still there. I checked the oil.. Its slightly low, so I am going to buy some and hopefully that fixes it. However, does anyone else have any suggestions of what might be the problem? && When i took the filler plug off.. I decided to smell it.. And I couldnt stop gagging for a couple minutes it smelled soo bad. Is it suppose to be like that? Should I change the oil all together? The car has just over 132k miles. Replys would be much appreciated! Thanks!
