1988 F-150, 4.9 straight 6 cyl, 2 w dr, 185,000 miles. I am replacing my valve cover gasket. I found 2 vacuum lines running under the upper intake manifold that appear to have been broken off. They both just stick out from under the protective accordion wrap. I had the fuel rail replaced a year back or so and think it may have happened then. There is a black one and a pink one (vacuum line) and both run around the back of the cover to a "tree" of three valves/switches that mount directly to the valve cover. Where is the broken end supposed to attach too? I can find no tips missing or any other broken ends. There are 3 "plugged" inlets on the vacuum tree that is mounted in the middle of the upper intake manifold.
have the same problem?
