Hi all again,
I took my C5 out for a very quick run and my motor is whining. I say "whining" it sounds more like it's in between a whine and a squeak. Then the motor started whistling ??? ??? ??? Then I went over a small bump and it stopped. Some times I can drive for quite a way without it whining.
I'll see if I can get my dad to take it apart and oil/lubricate it
