ok i picked up a 91 wagon its a6 and i have compreshon leaking in to the water chambers. i replaced the head and i didnt see any cracks in the sleves. i didnt see anything wrong it actuly looked pretty nice. it still wont run rite and it wont start without push starting it at like 3500 rpm. when it starts it sounds good but shoots ---- out the radiator cap and over heats. well i have gone through everything i can think of i might have to just d15b it.
