  Q: How to service and repair the upper intake manifold on Lincoln Blackwood?

  A:

  Service and repair of the upper intake manifold begins with disconnecting the battery negative cable followed by air cleaner assembly removal. First remove the three bolts which fasten the engine appearance cover before disconnecting the accelerator cable together with the speed control cable and return spring. After bolt removal position these parts out of the way. The upper servicing routine requires disconnecting the Evaporative Emission (EVAP) return hose along with the positive crankcase ventilation (PCV) valve tube and then concluding with coolant hoses where all physical connections receive plug installation to avoid coolant escape. You should disconnect the tuning valve electrical connector and then remove the cowl grille followed by taking out the bolts along with five clips and the wiring harness shield. Use a plastic scraping tool to clean all surfaces while carefully discarding old gaskets because metal scrapers along with abrasive tools should be avoided on sealing areas when removing the bolts, stud and balance tube. Disconnect and separate the electrical connectors linking the Idle Air Control motor and Throttle Position sensor and exhaust both the vacuum pressure hoses and EGR vacuum regulator electrical connector. Use a wrench to detach the bolts and the nut from the power steering reservoir bracket before safely placing it away and then remove the stud and oil fill tube. First detach the brake booster vacuum hose followed by the vacuum hose from the EGR valve and then unfasten the bolts on the EGR adapter. You need to disconnect the vacuum hose from the Vapor Management Valve (VMV) before placing it to the side. The upper intake manifold bolts should be removed while noting they are not reusable before extracting the upper intake manifold for gasket evaluation with cleaning applying to each sealing surface. The installation process requires examinations of both upper intake manifold gaskets for usability and notes the use of new upper intake manifold bolts. Begin installation by fitting all parts with their gaskets and upper intake manifold before tightening the bolts in two steps at 10 Nm (89 inch lbs.) followed by an additional 90-degree turn. The service technician needs to reattach the VMV vacuum hose before installing the EGR adapter together with a new gasket which requires bolted installation. The vacuum hose connections should run from the EGR valve to the brake booster while positioning the oil fill tube and reinstalling the power steering reservoir bracket with bolts. Next attach the nut while you join all necessary components between the differential pressure feedback EGR and EGR vacuum regulator and the IAC valve and TP sensor electrical connectors. The technician should install balance tube gaskets along with the balance tube before proceeding to mount the wiring harness shield together with its bolts and clips. Follow this step plan to reinstall the cowl grille and connect the intake manifold tuning valve electrical connector before reattaching the PCV valve tube together with coolant hoses. The repair process ends with connecting the EVAP return hose then reinstalling the cables and bracket before fastening everything with bolts before returning the accelerator cable and speed control cable and return spring. The process finishes with installation of the engine appearance cover together with air cleaner assembly and battery negative cable reconnection followed by filling the engine cooling system.
