i posted a thread re over heating a week ago for which i recived very good advise to drain down system and flush it all and bleed it like mad again and again. which due to family comitments i havent been able to do
however i have come across a new symptom which after reading a piece on the Wiki has got me scared.
checked the filler tank no water? filled up drove to work and check when it was home time, again no water in filler tank. both times the expantion tank was full to the brim.
So i filled the filler tank again drove it and when i stopped i could hear it boiling. So had a look and there was a boiling noise coming from ( i think around the water pump, a hissing noise comine from around the oil cooler (i think) and there was water p***ing out of the very top of the filler tank.
then i saw this
Mocki:
On the flat four WBX it is normal if you do short journeys this time of year, aircolds do it all the time, it's emulsified oil and the shape of the filler tube encourages condensation, and head gaskets on the WBX are not like inline engines, the oil and water rarely mix when they do go, most references to head gaskets "going" on these are really water jacket seals going, which result in air locks, which cause over heating, rather than oil and water mixing, and water dumping, or over pressuring, and chucking the water out of the top up bottle or blowing pipes off.
Keep an eye on the water level, in the header tank as well as the top up bottle, and the oil level, too, and most importantly the heater output, if it goes cold then hot then cold on your knee its airlocking, and the temp gauge may not show it, if it does it wont be at the same time as your knee feels it!
flem again
the heat from the heater is constant. does this meant i have water jackets seals gone or just that i realy need to drain and bleed it like mad?
