How to disassemble and assemble the intake manifold of Porsche in 2009?

The overall working process of removing the cylinder head from the cylinder block is as follows: remove the electrical connector, accessories and water pipes, remove the intake manifold, remove the exhaust manifold, and remove the synchronous belt (or chain) valve. The specific process is 1) Remove the electrical connectors, fittings and water pipes, and remove the fuel pump fuse. Start the engine. After the engine stops, turn the crankshaft 10s to release the fuel pressure in the fuel system. Disconnect the negative battery cable. Schematic diagram of operation: Remove the ignition coil, accessories and electrical connectors. Remove the outlet flange or water pipe, and remove the throttle plug. Process 2) Remove the intake manifold 0 1, remove the decontamination solenoid valve of the evaporative emission carbon canister from the intake manifold, and unscrew the bracket bolt. Disconnect the intake manifold air temperature sensor connector and the intake pipe from the throttle body. Disconnect the connector of the idle air control valve. Disconnect the connector of throttle position sensor. Disconnect the absolute pressure sensor connector of the bus bar. Disconnect the coolant hose from the throttle body. Disconnect all necessary vacuum hoses, including fuel pressure regulator vacuum hose and intake manifold control booster vacuum hose. Disconnect the throttle cable from the throttle body and intake manifold (cable operation procedure). 10 Remove the throttle cable bracket bolt from the intake manifold (cable operation step). 1 1 Remove the generator bracket bolt and the strap from the intake manifold strap. 12 Remove the locating bolt of the power steering hose and remove the hose from the repair place. 13 Remove the intake manifold bracket bolts from the engine block and intake manifold. 14 Remove the intake manifold bracket. Remove the intake manifold fixing bolts 15 in turn, and remove the intake manifold. Remove the gasket of the intake manifold. Process 3) Remove the exhaust manifold Remove the exhaust manifold bracket bolts from the engine block and exhaust manifold. When there is a heat shield, remove it together. Remove the bracket for the exhaust manifold. Remove the exhaust manifold fixing bolts in turn, and remove the exhaust manifold. Remove the gasket of the intake manifold. Process 4) Dismantle the synchronous belt (or chain) car. When removing the cylinder head for operation, just remove the timing transmission mechanism connected with the cylinder head. That is, remove the timing belt of the camshaft gear and separate the cylinder head from the cylinder block. Take Jaguar 1.6L and Bora 1.6L as examples, and remove the toothed belt sleeve; Then match the opportunity; Loosen the tension pulley bolt and remove the belt from the tension-released camshaft pulley. Instructions for removing the toothed sleeve: Remove the engine belt. Push the fixing lug up to the position indicated by the arrow in the figure below with a screwdriver, and then remove the toothed belt top cover. During installation, press the upper cover of the toothed belt onto the rear cover of the toothed belt and push the fastening bolt 1 until it locks. Timing operation diagram (Czech 1.6 liter, Porsche 1.6 liter), turn the crankshaft to turn the cam timing gear to the top dead center of 1 cylinder. The mark of the cam timing gear must be aligned with the mark of the toothed belt back cover. Remove cylinder head cover. Put the headgear on a clean mat. Remove the valve cover pad and pay attention to the integrity of the valve cover pad. Process 6: Remove the cylinder head
