Well I don't have a turbo, but if I did I would like that sound that blows off! And its not the alternator, my battery charges fine, and its not that kind of sound! Some more info that might help is that the ABS modulater, tank thing is leaking, the one beside the fuse box, and I keep filling it with the DOT3 break fluid, I can't find were the leak is, but break fluid does not run out that fast like every few weeks, once a mounth or twice! So does anybody know anything about that, is it easy to fix my self, or is it going to cost me!
