No water is coming out of the exhaust on my 1973 A4.
It has run very well for years until now.
I checked the following:
The engine starts up and runs beautifully.
All hoses have been disconnected and observed to have good water flow all the way to the muffler.
At the muffler good, hot, pressurized exhaust comes out.
At the water inlet into the muffler I noticed that with the raw water cooling line disconnected exhaust comes out at a pretty good pressure.
This seems wrong but I don't know.
The engine runs fine but the temperature shoots right up over 200 at idle within just a few minutes.
In summary it looks like I have good cooling water flow all the way through the engine but somehow it is blocked at the muffler and doesn't come out.
What do you guys think?
