What are the steps for disassembling and assembling a Jetta engine?

[HaydenRose]

Remove the fuel pump fuse, start the engine to release fuel pressure, and disconnect the negative battery cable. Disassemble the intake pipe assembly, remove the upper intake manifold assembly, and take off the lower intake manifold assembly to prevent debris from entering the passages. Remove the heated oxygen sensor, detach the exhaust pipe and gasket from the mounting bracket, and clean the exhaust manifold sealing surface to check for holes, damage, or cracks. Remove the protective plate to expose the generator belt, take off the belt, remove the engine crankshaft output pulley, and detach the triangular fixed bracket on the engine side. Loosen the cylinder head cover bolts in a diagonal sequence, remove the cylinder head cover, take off the valve cover gasket (ensuring its integrity), and then remove the cylinder head.
