Lots of dash left - I think this is a little sparse however -
But even this had the heater still in!

Hi Pete, thank you I tried this today and I have got somewhere but it is still not right! The reason behind me thinking that I have an airlock is that when I last drove the car, it got up to temperature a lot quicker than what I remember it did in standard format and when I returned home, it dumped a hell of a lot of water out of the overflow pipe underneath the n/s front of the car. When you opened the water reservoir, the water was not even warm though; suggesting the water was not pumping around. Also if you pumped the new 'bypass' pipe we have fitted, it did not seem to pulse the water in the reservoir, if you see what I mean.
So I have bleed the engine today, at first I still had no water coming out of the bled screw, I took it for a quick spin, and again the temp got up to half way on the gauge fairly quickly, it did not seem to creep up much more than that however. When I got it home, same thing, it dumped water out of the overflow pipe. However, when I took off the cap on the water reservoir, water boiled out and the water was hot, also if you pumped the new bypass pipe, it pulsed the water. So I had made some progress! I bled the engine again and this time I got water coming out of the bleed screw, took her for a another shorter spin, she was still warm from the previous run and the temp crept up to about 3/4's on the gauge and again dumped a small amount of water on the drive... Any other suggestions?
I would like to get her running fairly right before she goes into Project Nine Engineering. Of course I could get them to look at it, but the cost is increasing evermore! Although I do not think that I have been quoted a bad price for the work I have requested:
The 24k service on a 944 is £260
Prices for cam and balance belt change are:
Labour 4 hrs @ £58 =£232
Cam belt £29.81
Balance belt £44.83
Total £306.64 + vat
The only additional things needed with cam belt change may be replacement rollers or maybe some oil seals, cant really quote on these though as not all engines require these replacing so you would be quoted after belt is removed and before anymore work is done.
Clutch bleed is half hour labour plus fluid, total £37 + vat.
General check over of brakes would be done as part of the service.
I am going to get them to do a front wheel bearing too, which will be further expense and as I am used to wrenching on all my cars myself, I like to keep costs down! Infact, I think this will be the first car that I have ever given to a garage to carry out repairs on!
Simon, thanks for your comments, not a fan of our dash then! The whole dash will eventually be removed. It is, albeit a slight one, still weight loss and a look that we are trying to achieve. This is by no means a finished car, the doors will in fact have metal cut from them and aluminium panels fitted, polycarb windows are on the shopping list as well as the rear hatch and body panels will get replace with GRP ones, as and when we dent them beyond repair! You'll be surprised at how much the heating system weighed, particularly the fan unit and other means of getting air into the car, weight free, will be used.

hmmm
Do you know if it has any history of a head gasket change? do you know if your loosing any water before it overflows from the header to suggest that the gasket may be on it's way out? I can't remember but to save me re-reading the thread has the fan switch been checked or replaced?

It has had a head gasket change, from memory, in 2010. I do not know if it is losing water before it overflows. Fan switch or thermostat has not been replaced. The problems have only come about since we removed the pipework for the heater matrix though, removing the solid pipe that runs along the rocker cover and replacing this with a rubber pipe.
From what I have read on an American forum, the temp gauge getting to half way, is not overheating, its just whenever I go for a drive, water overflows when I stop.
Maybe the coolant cap I had the same symptoms with mine on the Dyno Day in Liverpool if you remember Pete? Guy replaced the cap and that was the end of the problem.
Also had similar on the 2.7.

Have you checked this replacement rubber pipe for damage, that area is extremely hot, I wonder what's going on with the rubber when the car is being run, is it by chance getting so hot that it's deforming and closing off that section, only to open up again once you stop. It's certainly something to look at, perhaps try refitting the OEM pipe and see if the problem goes away.
