I have a 1992 Audi CS100 quattro wagon with the 12v 2.8liter V6. I have recently come to the realization that the I need t o change the head gasket... No biggie right? Except that I can't find a technical manual of any kind and I am not too excited about starting to pull it apart with the idea of getting the specs later... Will I just be money ahead to drop a new v6 in there? If so what kind of 2.8liter will I need because I used to have a 1996 A6 and I can tell it isn't the same! Any help would be appreciated.

 

go to 12v.org and read everything. There is detailed information on this procedure. However, why do you want to change the gasket? Oil leak, oil in coolant, coolant in oil, low compression, what? Know that this procedure requires several special tools, which you can rent. The head gasket job leads to many, "while I'm in there" jobs that will add to the longevity of the engine, such as a new water pump, thermostat, belt, fresh coolant, valley pan gasket (which is a major source of oil leaks) etc. Further, you need a decent set of tools, a good torque wrench, and some specialty sockets for the head bolts. Gasket kit, $130, head bolts $45, some studs and nuts, $10-15, tool rental $?, machining the heads. It costs a couple of bucks just to do it yourself. Just know that going in.
