So here's the deal. The car idles very smoothly and drives good up until the "Boost" meter starts filling up (when I floor the pedal). All of the sudden, I hear a really loud rattling noise. Sounds like the end of the world, I swear. To be more specific, it sounds like as if there is a lot of rocks inside my engine. I blame the supercharger, but I could be wrong.
Has anyone ever faced the same problem before? I've heard of the infamous coupler issue which I'm going to replace anyways, but I don't think that it's the coupler that's making such a loud noise. Can anyone suggest what exactly needs to be replaced? Or maybe there a link to a supercharger rebuild/clean DIY somewhere?
The car has 90,000 on it and has had the transmission replaced already by the previous owner. Also, the oil pan is leaking, probably just the gasket that needs to be replaced. Maybe now is a good time to replaced the oil pump as well, huh?
Thanks in advance!!
Oh, and here's a video of the sound: http://youtu.be/eHPwJLWbQ-4
