I removed the bottle from the car last weekend and was about to put it back thinking it was filler cap that was faulty, when I saw a small hairline crack on the rear. So I blanked off the pipe holes and pressurried the botle with boiling water and the water started to leak from the crack.
I could n't get hold of a second hand bottle from anywhere, it appears as if they seem to sell real fast whenever someone is breaking an espace for spares. I wasn't going to buy a new one at nearly £90.
So I have managed to do a temporary repair that has stopped the leak. I have since done about 300 miles and not a drop has leaked.
What I did was get some sealant which is called 'stix all' and put that onto the exterior of the bottle. This stuff is so good it can withstand petrol and temperatures of +150 degress to -40 degrees and is extremely flexible. It can also be used on wet surfaces to seal the gaps.
I will replace the bottle when one comes up at the right price. But at the moment I am enjoying trouble free motoring in my espace.
