BMW X5 M57 6 CYLINDER Our diesel vehicle should definitely not be allowed to make chain noise in BMW vehicles due to excessive oil leaks, chain set change, chain set change. We recommend that the vehicle's chain set be changed, engine oil pump be changed and arm bearings be changed together. First, the intake manifold part of our vehicle was dismantled, then the water radiator and air conditioning radiator were removed. We lowered the vehicle's engine by removing the transmission and engine connection perimeter bolts. Our M57 coded engine is actually healthy engines, but software should definitely not be put into our vehicles. Again, the same BMW X5 M57 Coded BMW that gets up to the badge will come in our video. The original oil pump should definitely be renewed in chain change. It is one of the situations that should not be ignored in high hp vehicles. In the future, bearing winding crank winding situation should be taken into consideration. What is the Timing (Eccentric) Chain? The timing (eccentric) chain, called Timing Belt or Timing Chain, is one of the most critical parts of internal combustion engines. The timing chain, which is like a bicycle chain, can be single, double or triple depending on the model and engine structure of the vehicle. What does the timing chain do? In order for the ignition in the engine to be successful, the engine needs the appropriate amount of air and fuel mixture. For this, the engine valves must open and close at the right time. In order for the valves to open and close at the right time, the crankshaft and camshaft must rotate together at the same speed. The timing chain is what provides this synchronization of rotation. For this reason, it is also called the timing chain. Does the timing chain break? When the timing chain breaks, the rotation timing of the crankshaft and camshaft and the combustion process in the engine are disrupted. In this case, the piston and valves hit each other. If the timing chain is not replaced in time, it may break and if the timing chain breaks, it causes very serious repair costs.
