I have a 97 A4 quatro 2.8, and it is due for an oil change, it burns a little oil normally, but this time it seems to have burned a bit more than usual, I added 2 quarts the other day, and I have noticed the car idleing rough upon start up, and a bit of smoke until it gets warmed up. I have also been having some cooling system problems, IE: leaky/ blown hoses, So I have been having to add water/antifreeze more often. Anyways this leads me to beleive that I may have a blown head gasket. I am familiar with working on cars, but unfamiliar with Audi's and Audi specific problems. Are there any other problems with the car that may be causing this type of behavior from my car. Any help would be greatly appreciated.
