Yeah something I have just started to consider! I will replace the hose and see how it goes but I am not optimistic :(Quote:

what part of brissy are you hiding in?
check out the coke bottle bleed techinique I posted up, it'll easily identify any problems for you if the heads gone.
Geebung, although the vehicle is now on the sunny coast (was significantly cheaper to tow it to the in-laws place!)
Do you have a link? A didn't find your post in a search....
So would the indicator of head condition be visible oil in the coke bottle?
oil or lots of air will usually give away a gone head.
Soooo.....
Got back to the car yesterday... I replaced the offending hose, filled it back up with water and flicked it over.
The starter sounded very whiney and it refused to start. I hooked it up to another battery as it seemed sluggish but still no luck.
I tried the coke bottle trick but when I turned it over water spewed out around the bottle.... Does that mean excess pressure in the coolant i.e. head gasket stuffed?
yep, thats the copression gasses coming straight past the fire rings
How can I/We use parts of this thread and the others that deal with 300 TDi overheating problem to get the Wiki thread started?
Is it just a matter of copy and paste?

Bad luck there Matt, I agree with Dave that the head gasket is gone.Quote:

Check for cracks, warping of the head and if the motor was badly cooked get the top of the block checked for distortion.
Make sure that the air bleed hose from the thermostat housing is clear by blowing through it into the expansion tank and into the radiator tank, the plastic venturi is easily cleaned out by running a small 3mm drill bit through it .
As the Coolant is gone and needs to be refilled, I would be taking the radiator in for a rodding out and also think about doing the tropical mod as well.
When the head gasket goes, rubbish gets circulated around and lodges inside the tubes of the radiator core, this isn't obvious at first, but on a long pull the temperature rises slowly and when you stop and run the motor the temperature drops slow as well and this is due to the fact that the baffle in the radiator tank has a bleed hole big enough that you can poke your little finger through, the tropical mod is reducing that bleed hole size down to about 3 mm.
Check to see that the thermostat is opening by placing it in some boiling water on the stove, it should be fully open when the water nears boiling point and just as important, when it is cold make sure that the valve is closed completely and you can't see light coming past the sealing face.
Refill with 50 - 50 mix of coolant concentrate ( Green type for 300TDi ) and water .
If the heater is not effective, then the heater core is blocked as well, as it is a awkward job to remove and put back, the radiator repair bloke I took mine to for servicing suggested that I replace the heater core for a longer service life.
