— official information
The BMW M62B44 engine may have a knocking noise caused by a stretched timing chain. The maximum resource of the part is 200 thousand kilometers. The tensioner bar, the chain bar, the tensioner itself become unusable. It should be borne in mind that the Vanos system has the same resource as the chain.
At floating engine speeds, check the outlet manifold for air leaks. The reason may be a breakdown of the air flow meter, a faulty KVKG, problems with the throttle position sensors or their contamination.
If a leak appears, check the valve cover gasket, replace if necessary. A bath of cooling liquid may flow. In this case, change the bath, as well as the pump and intake manifold gaskets.
After 250 thousand kilometers, an increase in oil consumption becomes noticeable, it is necessary to replace the valve stem seals. The engine mountings are changed every 200 thousand kilometers.
When operating, keep in mind that the motor is picky about oil, it is better to use the material recommended by the manufacturer. Regular maintenance, use of high-quality consumables will ensure a long service life of the unit.
