    Cavitation Sound Behind Dash Area

    I purchased a 1973 RS backdate on a 1983SC chassis. I'm getting a strange cavitation type liquid sound coming from the dash area during some corning and braking. The oil cooler is still in the passenger wheel well with new braided lines running on the right side rocker area. Ideas?

    The 83 911SC had Vacume powered boosted brakes using a booster in the rear of the trunk. I would start my search there. Rob

    Might be a check valve in the brake booster system. I have a friend who rebuilt a motor and did it again searching for a noise and it turned out to be the brake check valve.
