    1970 wiper door & headlights open when starting

    Hi Guys,
    Can someone point me in the right direction.

    After my car sits for a few hours (454/390) and I start it up, the wiper door and head lights pop up for a few seconds and then shut back down.

    Could this be as simple as a check valve or is there something else I should look for?

    Thanks for your help.....

    Mark you have a leak on the control side of your system. Those are the small hoses some with a white stripe. It could be the check valve off the manifold that's the one with one input and two output lines. Also if you scroll down to the bottom of your thread there is a list of related discussions that may help you. Paul 18046

      I usually found that a vacuum line at the tank was loose.
