A check engine light or malfunction indicator lamp (MIL), is a tell-tale that a computerized engine-management system uses to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.).
Most engines have at least two main bearings— one at each end of the crankshaft. Additional bearings may be located along the crankshaft, sometimes as many as one bearing per crank pin, as used on many modern diesel engines and petrol engines designed for high RPM. [1] Some small single-cylinder engines have only one main bearing, [citation ...
Parts that are designed to wear inside a machine—e.g., bearings and O-rings—are intended to be replaced with new ones; consumables like paper, cardboard, fabrics, and product packaging are designed with a service life commensurate with their intended use. For example, grocery stores may issue customers a paper or plastic sack to carry out ...
For instance, .001 of an inch worn off of the engine's main bearings can cause up to a 20% loss in oil pressure. [6] Simply replacing worn bearings may fix this problem, but in older engines with a lot of wear not much can be done besides completely overhauling the engine. Particles in the oil can also cause serious problems with oil pressure.
Aside from the belt/chain itself, also common is a failure of the tensioner, and/or the various gear and idler bearings, causing the belt/chain to derail. Furthermore, in engines where the timing belt drives the water pump, failure of the water pump can cause the pump to seize, which can break the timing belt or chain.
