Ok my temp gauge went up, the engine sounded wierd, I had my car towed to a local shop. They said the engine was blown, it had oil and coolant leaking outthe exhaust!!!? I have heard of oil leaking out the cats due to whatever, but shouldnt that mean a new exhaust, not engine?

They told me this 2 months ago, since this I havent drove my car. I started my car up, after putting some oil and coolant in and it runs great!!!!!!! But when I stop, white smoke pours out the front. Someone said something about timeing belt, or a bad seal. Please help!!!!!!!!!!

p.s. its a 99.5 a4 quattro (standard) 115,000 miles
