I have a 1994 Plymouth Grand Voyager and just removed the Air Plenum to replace the spark plug wires. I found that 2 intake manifold bolts were loose, 2 were broken and one was missing. I believe the bolts were broken by a garage that left the broken bolts at some time in the past. Definitely no reason for one of the intake manifold bolts being missing. I removed the intake manifold and replaced the bad bolts. I also cleaned the injectors and replaced all the O-Rings on the injectors. After putting everything back together and starting the car, I found that there was a gas leak that appeared to be coming from the fuel rail or an injector. The rim of the valve cove had gas standing in it. I moved the van out of the basement and into the driveway and checked to see where the leak was coming from. I couldn't determine so I turned the van off. A little later I checked and the leak was gone. I have driven the van around a while but it isn't leaking any more. Would the fuel being de-pressurized cause the fuel rail to leak until the system is repressurized? If not, do you have any idea as to what would cause the leak to stop?
