What Causes the Smell of Burning Engine Oil in Motorcycles?

Motorcycles emitting a smell of burning engine oil may be caused by worn piston rings or valve leakage. Burning Engine Oil: Motorcycle burning engine oil, commonly referred to as oil blow-by, primarily occurs due to increased clearance between the piston rings and the cylinder. During engine operation, this enlarged gap allows oil to enter the combustion chamber. Another critical factor is issues with the valves, valve guides, or valve stem seals—any of these components malfunctioning can also lead to engine oil burning. During repairs, parts should be replaced based on the actual condition. Solutions: Replace the piston rings and valve stem seals (when replacing piston rings, pay special attention to the ring gap to avoid reoccurring oil blow-by from misalignment). Additionally, conduct a thorough inspection of the valves. If uncertainty remains about resolving the issue, consider replacing the valves as well. Neglecting repairs can impair the engine's power performance, as unburned oil in the cylinder fails to contribute to combustion, thereby reducing engine efficiency.

What are the causes of valve leakage?

Here are the causes of valve leakage: 1. Wear, burning, spots or depressions, and carbon deposits on the working slope of the valve and valve seat ring. 2. Excessive clearance between the valve stem and valve guide, causing the valve stem to wobble or bend, or the valve head to tilt, resulting in incomplete valve closure. 3. Weakened or lost elasticity of the valve spring or a broken spring can also prevent the valve from tightly fitting with the valve seat. 4. Small valve clearance causes the valve stem to expand when heated, and the tappet and rocker arm push the valve open, preventing it from fully closing and leading to leakage. 5. Prolonged operation of the engine at high speed and temperature weakens the valve spring tension, preventing the valve head from pressing tightly against the valve seat. 6. Failure of the decompression mechanism, causing the valve to close incompletely.

What is the oil pressure of the Volkswagen Touran?

Volkswagen Touran's oil pressure is determined based on driving speed. Basic criteria: The engine oil system pressure is around 1.0 at idle speed, and generally reaches 4.5kg during acceleration. For gasoline systems, carburetor models have 1.5kg pressure, while fuel-injected vehicles typically maintain 2.5-3.0kg for entry-level models, with maximum pressure not exceeding 3.5kg and minimum pressure never below 2.5kg. Fault issues: If pressure becomes extremely low during driving, triggering warning lights, promptly check whether it's a sensor problem before evaluating the oil pump. If the pump's output pressure is insufficient, immediate repair is necessary. Routine maintenance: Regularly inspect oil hydraulic pressure, examine sensor connections, and periodically clean oil passages to prevent clogging that could cause engine damage.

Why does the rear quarter window of the new LaCrosse rattle?

The rattling noise from the rear quarter window of the new LaCrosse is caused by loose door screws or lifting brackets, or aging window glass sealing strips. Loose door screws or lifting brackets: When driving on bumpy roads, the rattling noise from the car window glass is due to loose internal fastening screws or lifting bracket detachment. To fix this issue, visit a 4S shop to have the staff tighten the loose door glass. Aging window glass sealing strips: Aging door glass sealing strips are one of the reasons for window rattling. If the noise occurs in a new car, there's no need to replace the strips. Simply apply lubricant evenly on the strips and try raising and lowering the window several times to see if the noise diminishes. If the sealing strips are severely aged, they should be replaced directly.
