Coolant Blow-By in Breather-Hoses
In every car I have every owned, this spells slow painful death. Please tell me there's a audi logical solution, other than cylinder rings. There's no chocolate milk in the oil pan yet, but i dumped water out of the breather hoses & there is a gurgling sound coming from inside the dash

gurgling sound coming from inside the dash = blown heater core.
Have fun.

I'm thinking blown head gasket
I'm thinking blown head gasket & cylinder is pushing exhaust up into coolant passages, creating gurgle in dash. Thats what happened to an old 84 subaru I had. I keep driving it until 1 of the cylinders finally had enough. It limped to the junk yard.

if your car is a 93-95 Audi 90, the sound in the dash is the heater core, 99.999999999999999999999999999999%

Yes, my car is a 1995 audi sport 90. Yes, I believe that the heater core is the issue in the dash. Members here, said its not if it happens, but when it happens. But the coolant in the breather hoses concerns me. because it means there is condensation coming from somewhere in the engine. does anyone else here have any input?

Re: "I dumped water out of the breather hoses "...
Are you convinced it's coolant and not just water? I often get just plain water that pours out of my hoses when I remove them with my Noise-damper.
The CCV hoses lay fairly flat and simple condensation can gather there. Short trips aggravates this. Hot engine cools and water condenses in it, more-so in cool weather, then this is expelled as steam, it cools in the hoses; and collects.
If you have coolant loss, clean oil in sump and new gurgling noise from behind the dash, perhaps the leak is elsewhere, such as the core itself.
