1.9Tdi 115. Engine swap?

It is rare that the injectors have an issue in service, the problems start if they have to be removed for one reason or the other. The AJM is prone to head gasket failure.

Thought I would give you an update. Got head off ok (pretty tight and a bit fiddly), you could actually see where there had been some tracking marks between the no 2 cylinder and a coolant channel, hence the pressure build up. Got the head pressure tested etc and skimmed, gew gasket and bolts and it's all back together.
Done around 40 steady miles in it and it seems ok, had to top up about 1/2" of water but hoping thats just it finding the level.....bottom pipe is hot and not rock hard and full of pressure. Will take it on a longer run and do a few motorway miles to test it a little more today.
Only thing that is now puzzling me is this. I don't get any heat coming throught the heaters until I turn them right up to Hi, then if I turn it down to 28/29 it is luke warm and any lower than that and it is cold?? I am hoping that this is a tempreture sender/sensor problem and not something still wrong inside the engine.......
Forgot to mention, both fans also come on and stay on within a minute of starting the engine, not sure if this is normal?

You have a circulation issue there, did you fit a new water pump when replacing the belt? The fans coming on like that is normal if you have the A/C set to auto, try it on ECON and see if they come on.

I fitted new water pump, rad and thermostat before I went for the head gasket so they are all ok. I am told there is a heater valve (not sure if thats the correct name) that sits behind the header tank? Could this be causing the prob? The heaters work but only if you turn them up to Hi.

Car seems to be running fine otherwise, had to top the header tank up a little twice but it's settled down now and I've done 100mls or so and it's ok.

Is this a Golf or a Sharan?

There is a valve for the auxiliary heater, one for the EGR cooler and an additional electric water pump, I think you have an air lock.

Ok Thanks for that Crasher, makes sense as the system was getting very pressurised before I did the head gasket. Obviously a big car/heating system, any tips for bleeding it out please?
