Can a Car Start with an Oil Leak?

1 Answers

Car cannot start with an oil leak. Solutions for engine oil leakage are as follows: Replace failed oil seals: Many moving parts on the vehicle (such as oil seals and O-rings) may leak oil due to improper installation, misalignment between the shaft neck and the oil seal edge, or eccentric rotation. Some oil seals may lose elasticity over time due to rubber aging. Leaks should be promptly addressed by replacement. Tighten all fastening nuts to the specified torque: All fastening nuts on the vehicle must be tightened to the specified torque. If too loose, the gasket won't be compressed enough, leading to leaks; if too tight, it may cause metal protrusions around the screw holes or thread stripping, resulting in oil leakage. Additionally, if the oil pan drain plug is not tightened or becomes loose, it can lead to oil loss and potentially cause severe engine damage such as "bearing seizure and crankshaft locking." Pay attention to the role of gaskets: Gaskets between static parts of the car (such as joint surfaces, covers, housings, sealing pads, and flat enamel covers) play a crucial role in preventing leaks. If the material, manufacturing quality, or installation does not meet technical specifications, they may fail to seal properly, leading to leaks or even accidents. For example, oil pans or valve covers, due to their large contact area, may not be tightly sealed, resulting in oil leaks.

Why does the car body shake at speeds between 120 and 140?

The reason for the car body shaking at speeds between 120 and 140 may be due to poor dynamic balance of the two front wheels. You can have the dynamic balance adjusted to see if it resolves the issue. Here is an extended explanation: Tire Composition: A car's wheel is an assembly consisting of the tire and the rim. However, due to manufacturing reasons, the mass distribution of this assembly is not perfectly uniform. Phenomenon: When the car's wheels rotate at high speeds, this can lead to a dynamic imbalance, resulting in wheel shaking and steering wheel vibration during driving.
