Symptoms of a leaking head gasket over pressurising the coolant system.
If it's getting out of the pipes and cap your pipes and cap are knackered to allow it out. Over pressuring on a Peugeot diesel is a sign that the head gasket is on it's way out. You can postpone the inevitable with a bottle of K-Seal but it'll need doing sooner or later. A mate's wife had a 306 estate that started doing it so he took it in for MoT so he could flog it quick with a years ticket. While in the MoT bay with the testers head under the bonnet and the engine running, there was a loud pop and the tester emerged from under the bonnet covered in anti-freeze as the pressure had split the header tank......It won't get into the oil or try to burn coolant, it'll just put combustion gases into the cooling system.

It has to last until Friday. I shall then persuade my parents to let me flog it pronto!! Anyone got a cheap bike for sale?
Are you 100% sure it's the head gasket gone? The coolant system is under pressure anyway as it runs at over 100 degrees. It's sealed in order to raise the boiling point of the coolant, so it can do its job more efficiently (just like a pressure cooker). It could just be knackered pipes as they go brittle and split with age, so don't write the car off just yet.
Any car garage can do a simple test for gas in the coolant bud, then you'll know for sure.

Damn it man, does nothing go right f' thee?
Put it this way - it went so well, that towards the end of the conversation, they were implying I'd caused the head gasket failure deliberately.
