Engine damage due to black oil (engine rosak kerana minyak itam) can occur for several reasons related to engine lubrication and maintenance. Here are the key points based on the provided search results:
Oil Combustion: Black engine oil can be a sign of oil getting burned inside the cylinder along with gasoline. This can be caused by issues with the piston rings not effectively preventing oil from entering the combustion chamber (as mentioned in Search Result #1).
Oil Level: Low oil levels or frequent top-ups may indicate a problem with the engine (as mentioned in Search Result #3). Running an engine with insufficient oil can lead to increased friction and heat, potentially causing damage.
Oil Leaks: Oil leaks, as discussed in Search Result #4, can lead to insufficient lubrication, resulting in engine damage. Leaking oil should be addressed promptly to avoid engine problems.
Maintenance: Proper engine maintenance, including regular oil changes, is crucial to prevent engine damage. Delaying oil changes, as highlighted in Search Result #6, can lead to a lack of lubrication, increased friction, and damage.
Valve Seal Issues: Valve seal leaks (as mentioned in Search Result #2) can also cause oil to leak into the combustion chamber, leading to black oil and potential engine damage.
To avoid engine damage caused by black oil, it's essential to address any oil-related issues promptly, perform regular maintenance, and ensure the engine has the correct oil level and quality.
