Question

if an exhaust valve leaks during engine operation, maverick air is drawn into the combustion chamber, causing a lean air-fuel mixture. what symptoms will a leaking exhaust valve cause during engine operation

Answer 1

Reduced engine power: The engine may not produce as much power as it normally would, and it may feel sluggish or underpowered.

Decreased fuel efficiency: The lean air-fuel mixture may cause the engine to burn fuel less efficiently, resulting in reduced fuel economy.

Higher exhaust gas temperatures: The lean air-fuel mixture may cause the exhaust gases to be hotter than normal, which can be indicated by higher exhaust gas temperatures.

Knocking or pinging sounds: The lean air-fuel mixture may cause the fuel to ignite prematurely, which can create knocking or pinging sounds.

Misfiring: The lean air-fuel mixture may cause the engine to misfire, resulting in rough operation and potentially causing the check engine light to come on.
