The most common metal plugs used in automotive engines are made from plated mild steels, stainless steels, brass or bronze. In some high-performance engines the core plugs are large diameter cast metal threaded pipe plugs. [3] Core plugs can often be a source of leaks due to corrosion caused by cooling system water. [4]
While running the leaking pump seal drained cooling water to a level where the pump could no longer return water to the top of the radiator, so water circulation ceased and water in the engine boiled. However, since water loss led to overheat and further water loss from boil-over, the original water loss was hidden. After isolating the pump ...
Head gasket leaks are classified as either external or internal. External leaks are visible as oil or coolant on the outside of the engine (typically underneath). Internal leaks are when the fluids enter another circuit and may result in changes to the coolant or oil.
Until the early 20th century, blow-by gases escaped from the crankcase by leaking through seals and gaskets. It was considered normal for oil to leak from an engine and drip onto the ground, as this had also been the case for steam engines in the decades before. Gaskets and shaft seals were intended to limit the leakage of oil, but they were ...
However, uncooled EGR designs do exist; these are often referred to as hot-gas recirculation (HGR). Cooled EGR components are exposed to repeated, rapid changes in temperatures, which can cause coolant leak and catastrophic engine failure. [9] [10] Unlike spark-ignition engines, diesel engines are not limited by the need for a contiguous ...
A post shared on Facebook claims Tesla CEO Elon Musk announced the creation of a water-powered car engine. Verdict: False There is no evidence Musk has announced such a creation. Fact Check: Tesla ...
