Q how to check blow by on a diesel engine

To check blow-by on a diesel engine, which indicates wear or damage inside the engine, causing combustion gases to escape past the piston rings into the crankcase, start the engine and let it reach operating temperature. Remove the oil filler cap or the dipstick. If there’s noticeable smoke coming out, that’s a clear sign of blow-by. Be cautious, as a small amount of vapor is normal, especially in cold weather. Another method is to place your hand over the opening; if you feel significant pressure or air puffing out rhythmically with the engine’s RPMs, this is another indication of blow-by. For a more quantitative assessment, a manometer can be used to measure crankcase pressure. Always refer to the engine manufacturer’s specifications for acceptable levels. It’s essential to diagnose and address the underlying issues causing blow-by, as it can lead to reduced engine efficiency and higher emissions.

Q can bad spark plugs cause engine knock
TeresaTrevelyan

Yes, bad spark plugs can indirectly lead to engine knocking. Often, spark plugs are crucial for proper engine combustion. When they’re worn or faulty, they can cause incomplete or improper combustion of the fuel-air mixture. This misfiring can lead to pre-detonation or “knocking” where the fuel ignites prematurely under high pressure before the optimal point in the combustion cycle. This not only affects engine performance but can also cause damage over time. Good maintenance practices, including regular inspection and replacement of spark plugs, are recommended to avoid such issues and ensure smooth engine operation. Always consult your vehicle’s manual or a professional mechanic for the best advice tailored to your specific engine type and condition.

Q how long can a diesel engine idle

A diesel engine can idle for an extended period, technically ranging from a few hours to several days, under controlled conditions. However, idling for long durations is generally not recommended. Prolonged idling leads to inefficient fuel usage, increased engine wear, and unnecessary emissions. For modern diesel engines, excessive idling can result in the buildup of carbon deposits within the engine and exhaust systems, potentially causing operational issues like reduced efficiency and power. It can also adversely affect the diesel particulate filter (DPF), necessitating more frequent regeneration cycles. Industry best practices suggest limiting idle time to the minimum necessary for operational needs, such as warming up the engine in cold weather for around 5-10 minutes. For drivers concerned with comfort during breaks or rest periods, auxiliary power units (APUs) or other idle-reduction technologies provide an energy-efficient alternative, reducing the need for extended engine idlin...

Q how to clear check engine light

1. Let it clear itself: The best way to clear a check engine light is to fix the issue that the ECU is reporting and let it clear itself. Once the ECU recognizes the problem is fixed, it will eventually turn off the check engine light. 2. Use an OBD2 Scanner: The next way you can clear a check engine light is by using an OBD2 scanner. This small device will read trouble codes, tell you what they mean, and clear them. Here’s how: – Find your car’s OBD-II port. It should be located somewhere underneath your steering wheel. – Plug your diagnostic tool into the OBD-II port. – Turn your ignition on. – Wait for a few moments while your tool communicates with the ECU. – Your scanner will have a function to clear or reset check engine light. Use this function and the light should be turned off (Note: It will come back on unless the problem is fixed). IMPORTANT NOTE: NEVER attempt to disconnect the battery to clear the light. Disconnecting the battery in some...
