Hello i have a 2003 Audi A4 1.8T FWD and i am pretty sure some of the gaskets are leaking. For instance where the exhaust comes up into the exhaust manifold oil is being dripped onto that causing it to smoke. I can see oil residue build up all around this area. Also, on the bottom of the engine their is minor oil. I was wondering how much it would cost including labor to replace all of the gaskets? Also is it just the gaskets causing this?

Also, coolant used to come out of the coolant expansion take overflow pressure thing on the bottom of the tank when the car started to get warm. when i took the cap off of it there was steam coming out of the tank too.
