BMW Exhaust Manifold

When the engine is on, every cylinder generates exhaust gases, and exhaust manifold gather these gases into one pipe. Generally speaking, exhaust manifold is made of simple cast iron or stainless steel units. Here are some advisable hints showing your exhaust manifold is failing: you hear a loud noise from engine when you are driving; the performance of your engine is not as good as it used to be; Check Engine Light (CEL) is on; a smell coming from the engine compartment. For you and your family safety, if the exhaust gases do not exit through the right way, it can be a fire hazard melting. It is a task for you to check the situation of exhaust manifold. If it is failing now, do not hesitate to get a new one. And you don't need to go too far away since you are already here. We provide sincerely dedicated service with BMW OEM exhaust manifold with a surprising cheap price.

BMW Exhaust Manifold Parts Questions & Experts Answers

  • Q: How to remove and replace the turbocharger and Exhaust Manifold in 4-6 cylinder for N54 six cylinder engine on BMW 335i?
    A:
    Eliminate both pre-catalytic converters, and set free right side tie rod acting on the steering rack. Then, it is necessary to uninstall the inteRcooler, turn the engine with idle running until the coolant drains, and then remove the coolant expansion tank. Go on to take out the coolant pump together with two vacuum reservoirs and the air box and air intake duct as well. Unbolt the oil return bolt and the bracket and carefully extract the oil return line from the engines block. At the inter-turbo charger, remove the fasteners and coolant supply hoses. It is allowed, however, to use pliers, but only for getting a firm grip on the flange of the coolant supply line before removing it, although not the pipes. Undo the fasteners of the coolant inlet pipe and the coolant return line, then pull out the coolant return line and the coolant supply line, using the pliers where necessary but should ensure that the wastegate valve linkage is not spoilt. Now unbolt the retaining plate as well as the heat shield; install the heat shield and swing out carry it to the rear. The supply pipe for the coolant can also be disconnected and this goes hand in hand with the heat shield. Disconnect the fasteners from the bracket and place this bracket on top of the cylinder head and the next step is to also disconnect the fasteners from the oil supply line bracket and liberate this line. Remove all the exhaust manifold bolts, and remove exhaust manifold/turbo charger from upper side by pulling out but be careful not to damage wastegate valve linkage, also remove the vacuum hose fitted on wastegate valve. If replacing the turbocharger, unbolt the oil supply line fastener and relocate it on the new unit; graphite gaskets are always required. The rest is very much similar to removal but the new O-rings, gaskets, and hardware is used and the hardware thread is lined with anti-seize lubrication. Last, scan for fault memories with a BMW scan tool and delete, and the air intake and exhaust systems for any signs of leakage.
  • Q: How to remove and install the exhaust manifold for cylinders 4-6 on BMW X3?
    A:
    Remove the exhaust manifold for cylinders 1-3 and the oxygen sensors. For the M54 engine, also remove the secondary air pump. Take out the fasteners from the rear exhaust manifold and then remove the manifold. During installation, which is the reverse of removal, ensure to clean the sealing surfaces of the manifold and cylinder head, use new gaskets and hardware, and check the exhaust system for leaks.
  • Q: How to safely remove and reinstall exhaust manifolds while avoiding damage to oxygen sensors in six cylinder engine on BMW X5?
    A:
    To avoid damaging oxygen sensors, remove them prior to exhaust manifold removal and ensure not to mix up oxygen sensor connectors by marking them before disassembly. Use new hardware and gaskets when reinstalling exhaust manifolds. Begin by removing the intake manifold cover and separating the post-catalyst oxygen sensor connectors. With the engine fully cooled, work above the exhaust manifolds to separate and remove the precatalyst oxygen sensors. Safely raise and support the car, then remove the front end reinforcement, ensuring to follow the proper procedure to avoid chassis or front end damage. Next, remove the front stabilizer bar mounting brackets and rubber mounts, and detach the stabilizer bar links. Separate the rear mufflers from the center muffler, then remove the center muffler. Proceed to remove the post-catalyst oxygen sensors and the exhaust manifold mounting nuts, followed by the removal of the front and rear exhaust manifolds along with their catalytic converters. For installation, reverse the removal steps, ensuring to clean sealing surfaces, replace gaskets, replace manifold and front pipe mounting nuts, and coat fastener threads with anti-seize paste.
