    In order to tidy up the mess after a persistent fuel leak i am trying to remove the airbox on my 1971 Euro spec 246GT.

    Can anyone give me any tips on removing the PCV valve which appears to be one of the things holding the airbox in place?

    I can get a 27mm wrench underneath the back of the airbox to the bottom of the valve but can't find a tool that will locate properly on the 27mm hexagonal nut that sits inside the airbox, this seems to be very difficult to get a grip of and is made from soft metal, so rather than chew it to bits, i thought i'd ask the experts, can anyone help?

    I've tried a variety of combination wrenches and adjustible spanners, no success so far.

    I will of course post nice pictures of the car in return, which i will hopefully take this weekend once the sun comes out.

    Thanks in advance

    Andy

    Greetings Andy,
    'been there, done that. I was able to get just enough purchase on the nut with a large spanner (AKA Crescent Wrench). Fortunately, the previous maintainer had not cranked it down too tight, so I was able to ease it loose without damaging it. Failing that, you might try to fab a tool by heating an old wrench and bending the handle, or by cutting a 27mm slot in a small piece of steel plate and welding a handle on it. I believe you can also get a spanner with a hinge-handle on it. Lastly, tape the jaws of channel-locks or needle-nose vise grips. Some of these techniques are more primitive than others; hopefully, one of 'em will work for you.
    You mentioned "the mess." May I suggest pulling the carbs & adapters so that you can clean the top of the block in the valley between the heads. I mopped up nearly a half-inch of thick fuel 'sludge' that had collected there from weaping Webers. Not only did I eliminate a fire hazard, I also cleared up the nasty scent of old fuel. The garage smells much better now!
    Good luck & keep us posted
    Cheers,
    Coop

    Thanks for advice.

    Job done. It didn't help, as i later realised, that one set of the carbs had a recess cut into it to allow better access to the top of the fluffer valve, but it wasn't opposite the fluffer valve, it was on a different set of carbs.

    Airbox removed. Also provided opportunity to tighten fuel lines and make sure no more leaks. Feel calmer now.

    All clean and tidy too.

    Andy
