It depends on the state you live in, as regulations vary. However, in most states, a car with a check engine light on will not pass the state inspection. The check engine light signifies that there are one or more problems with the engine that need to be addressed. You should have the issue diagnosed and repaired before attempting to have the car inspected. In some cases, it might be something minor but ignoring the light can often lead to bigger and more expensive issues down the road.

Q how to adjust hydraulic lifters with engine running
NicolaBlume
UriahJulian Release Time: 3月 22, 2024, 5:48 下午
Adjusting hydraulic lifters with the engine running is a somewhat advanced task, primarily performed on older or performance vehicles equipped with pushrod engines. To proceed, start the engine and let it reach operating temperature. This ensures the hydraulic lifters are fully expanded from the engine’s heat. Identify the rocker arms and listen for any tapping sounds indicating loose lifters. One at a time, slowly tighten the rocker arm nuts (or adjustment screws, depending on the engine) until the tapping stops, signifying that the lifter plunger is just making contact with the pushrod. From there, tighten the nut an additional quarter to half a turn. This additional tightening preloads the lifter, ensuring it maintains contact without leaving it too tight, which could keep the valve open and lead to engine damage. Use caution, as the engine components will be hot, and moving parts pose risks. Always wear appropriate safety gear. Not all engines are suited for this method. Cons...

Q how warm does a block heater keep an engine
NicolaBlume
JaySilas Release Time: 3月 22, 2024, 6:25 下午
A block heater warms an engine’s coolant, which in turn keeps the engine block warm, facilitating easier starts in cold weather and reducing engine wear. Typically, block heaters do not make the engine hot; instead, they maintain a temperature around 10°C-20°C above the ambient temperature. This moderated warmth is sufficient to keep the oil less viscous, allowing for smoother circulation and lubrication upon startup. It’s essential in colder climates, extending the life of your vehicle by reducing stress on the engine during cold starts. Investing in a good quality block heater and using it when temperatures drop significantly can save you from potential engine troubles and ensure your vehicle remains reliable, especially in freezing conditions.

Q can coolant leak into engine
NicolaBlume

Yes, a coolant can leak into the engine. This is a serious issue often referred to as a “coolant leak” which could lead to overheating and severe damage to the engine if left untreated. The coolant can leak into the engine oil, mix with it, and cause it to become milky. It can also leak into the engine’s combustion chamber.
