Engine Diagnostics and Repair
Understanding your vehicle’s engine diagnostics and repair needs is crucial to maintaining its performance and longevity. Regular inspections, along with addressing any issues indicated by the check engine light (CEL), can prevent costly repairs and ensure your vehicle runs efficiently.
Check Engine Light
The Check Engine Light (CEL) can illuminate for hundreds of different reasons. While some issues that trigger a diagnostic trouble code (DTC) require immediate attention, most are related to emissions and do not necessarily pose an immediate risk to your vehicle’s safety. However, it is important not to ignore the CEL and have the issue diagnosed promptly to determine the severity of the problem.
Engine Mounts
Engine mounts secure the engine to the vehicle’s frame. When mounts become worn, collapsed, or grounded against the frame, they can transfer engine vibrations through the chassis and into the passenger compartment. During routine maintenance, motor mounts are inspected for signs of wear or collapse to ensure the engine remains properly aligned and isolated from the chassis. Examples of both separated and collapsed mounts are displayed below in the image.
Intake
The air intake system supplies fresh, filtered air to the engine, which is essential for combustion. Sensors within the intake system relay information to the Engine Control Module (ECM), which adjusts the fuel mixture and spark timing to optimize performance and fuel efficiency. A clean and properly functioning intake system ensures your engine operates at peak efficiency.
Timing belt
The timing belt ensures proper synchronization between the crankshaft and camshaft. A worn, loose, or contaminated timing belt can negatively impact fuel economy and engine performance. In worst-case scenarios, a broken timing belt can cause significant engine damage. Replacing the timing belt at manufacturer-recommended intervals is critical to preventing engine failure.
Engine Valve Adjustment
Valves regulate airflow and fuel mixture into the engine’s combustion chamber and allow exhaust gases to exit. Proper valve clearance is vital to maintaining engine performance. Incorrect valve adjustment can lead to poor performance, increased engine noise, and even engine damage. Regular valve inspections and adjustments are necessary to keep the engine running smoothly.
If your check engine light (CEL) comes on, it’s important to have it diagnosed as soon as possible. While some issues may not be urgent, the CEL could also indicate more serious problems. A technician will read the diagnostic trouble code (DTC) to determine the cause and recommend the appropriate repair.
Timing belt replacement intervals vary by vehicle but are typically between 60,000 and 100,000 miles. Check your vehicle’s owner’s manual for the recommended replacement schedule. Failing to replace the timing belt at the recommended interval can result in severe engine damage if it breaks.
Signs of a failing engine mount include increased vibration in the passenger compartment, clunking noises during acceleration or deceleration, and engine movement when starting or shifting gears. If you experience any of these symptoms, it’s important to have the engine mounts inspected.
A ticking noise from the engine could indicate improper valve clearance. Valves that are too tight or too loose can cause engine noise and negatively affect performance. Having the valve clearances adjusted at the recommended intervals can prevent further issues.
A dirty or clogged air intake system can restrict airflow to the engine, reducing fuel efficiency and performance. It can also cause the check engine light to come on. Regularly replacing the air filter and inspecting the intake system helps ensure optimal engine function.
Yes, if the valves are not adjusted properly, it can lead to poor engine performance, excessive wear on engine components, and in some cases, engine damage. Regular valve inspections and adjustments are key to preventing these issues.
Common causes of a check engine light include issues with the oxygen sensor, catalytic converter, mass airflow sensor, or spark plugs. It can also be triggered by problems with the emissions system, such as a loose gas cap or an EVAP leak.
