    Default CX leaks

    "Queeny" the 1981 CX 'Familiale' I drove back from Queensland earlier this year has developed a leak. Dribbling from around the yellow box underneath and forward of the drivers feet.

    Tried replacing the rubber "t" found in the yellow box to no avail. Then checked with Bob who told me it was most likely a brake line above and forward of the yellow box. This put it under the heater air intake.

    Bob told me that it was best done by removing the front wheel, weather cover and away you go. He had the necessary parts which he kindly put in the mail to me.

    pic 1 shows mudguard area with wheel removed.
    pic 2 shows weather cover removed and leaking line.
    pic 3 shows the front of the 't' where a fracture is leaking.
    pic 4 shows the two new lines.
    pic 5 have moved the scuttle drain to right to clear area.
    pic 6 the other end of the two lines that were replaced.

    Above and behind the obvious leak was a second line that had been cut by the clamp after years of friction. Removed and replaced it with the plastic line. What a sod! Very difficult to hold the clamp in a position where you can tighten it. Half an hour and a 7mm socket in the bowels and still not tightened.

    At the top the plastic line, after heating in hot water, slipped on to the metal pipe joining the return to the LHM reservoir. (old line and pipe cross near centre of image 6 - the new plastic line was softening) The other end of the moulded line has the screw driver in it to ensure it doesn't drop back. It will need a short joiner to link it to the original return line. The new piece is shorter than the broken one.

    The rubber gets old, I've found once it starts leaking, you simply can't get a permenant fix until you replace the octopus. You see, no matter how often you trim the ends and rejoin them. It still splits further along where you have joined it, or pushed the hose over any sort of barb.

    Not really cheap, but the next one will probably last 20years too!

    The other option is make up your own joiners/tees etc. and use straight lines. However, for the hassle involved for most people, just buy the 'octopus' and marvel at how supple it's new rubber is!

    I have replaced these lines with new ones as well. I have also done the main octopus and the small return lines from the steering governor. The genuine parts aren't cheap for the bits of rubber tube that they are, but they are good quality and nice and flexible. And as Shane says, they should last another 20 years.

    Not much access at some of the connections - and working upside down under the car with all that oily dirty s**t dropping in your face isn't much fun. But it did cure the minor oil leaks. My car is nice and dry at the moment. And it stays a lot cleaner for that.

    I have also had (on a previous CX) one of the nylon return lines abrade thru til it started leaking. The quick fix was to cut it at that point and use a bit of rubber return line to rejoin. I used a cable tie to tension the line so that it didn't rub anymore. That fix lasted until the car was sold.

    Ross, you are telling us you bought a CX that was leak-free! Wow.

    Good information. Mine has leaked for 6 years, despite many fixes here and there. Octopuses are good. Heaven knows where it is coming from this time!!

    Thanks for the photos and best wishes for Xmas and the new year.

    Not only was it leak free it performed faultlessly on the drive back (apart from the broken belt)

    The leak started when I loaded a pallet of books into the boot. That and turning in tight places seemed to stretch the rubber that fraction too far I suppose.

    Happy Christmas and a Wonderful New Year to you and your family also.

    We must have a CX Day/weekend in Denmark in the New Year.
