However, you still haven't told us how this actually happened you naughty boy - were you messing again?:sly
well, you know, I was just poking my nose about in the engine bay and er, well, my angle grinder cut it off....sir....
actually, the story goes like this. The pipe is off my Mazda MX3. I used one of those gas refill kits to try to find the issue, I found the problem to be my condenser, which was leaking out the back so hard to spot. I ordered a new one of a Mazda club member, and when it arrived, set about the swap over. well, the main pipe from the compressor was pretty much welded on. it was very awkward to get to, as most things are inside a mazda engien bay, but even so, I have to the tools and this nut wasnt budging.
I ended up having to remove the whole lot, just to get the pipe out, and the nut had been tightened on at an angle, and over time, and pretty much become welded on, hence why I attempted to angle grind the thing off! ah well!!
