Hard vibrating coming from underneath car??
I'm checking around to see if anyone knows about this. I have a 1997 that has a hard vibrating that sounds like it is coming out towards the back, bottom end of the engine. I took the Vette into the Chevy dealer awhile ago for a new gas filter and asked about this. I recall the mechanic telling me it was a standard issue with the 97 Vette and that unless the noise was bothering me, it didn't need repair. At that time he told me what is was, but I can't recall now. Does anyone know what this is? The noise now bothers me too much and I'm thinking about getting it fixed. Thanks!
If I had to describe the noise, it sounds like a tin plate vibrating against an oil pan. I know nothing is loose because I'll looked thoroughly under the car when it was running and again, the Chevy mechanic said it was a common problem for a 97 but it didn't require work.
Any help is greatly appreciated. Thanks!
