To say "no one is knowledgeable here" is a very bold, and incorrect statement to make. And besides, what's the going rate for giving a correct (and fast) answer here? Oh yeah, that's right......NOTHING. If you get an answer, and hopefully a correct one, it's from the kindness of our hearts since we all share the same interest. Some answers that are given actually might require a little research, since not everyone here is a walking encyclopedia of mechanical knowledge. And if you don't get an answer right away, try researching it yourself, you might actually learn something. If you want an informational automotive website where you can go and ***** about not getting an answer, then join one where you actually have to pay a pro to get an answer. If you don't know where to find one, I have the answer to that one!!!!!
