Oil leakage on the left side below the engine of a Suzuki Gixxer motorcycle could be caused by a few potential issues. Here are a few possible reasons for oil leakage in that specific location:
Gasket or Seal Failure: The most common cause of oil leakage is a failure of gaskets or seals in the engine. Gaskets and seals are used to create a tight seal between different engine components, preventing oil from leaking out. Over time, these gaskets and seals can deteriorate due to wear and tear, leading to oil leakage. It's possible that a gasket or seal on the left side of the engine has become damaged or worn out, causing the oil to leak from that area.
Cracked Engine Case: Another possible cause of oil leakage could be a crack in the engine case. The engine case is the main housing for the engine components, and if it develops a crack, oil can leak out. Inspect the left side of the engine case for any visible cracks or damage that could be causing the leakage.
Loose or Faulty Oil Filter: The oil filter is responsible for removing contaminants from the engine oil. If the oil filter is not properly tightened or is faulty, it can cause oil to leak from the left side of the engine. Check if the oil filter is securely tightened and in good condition. If necessary, replace the oil filter with a new one.
Oil Drain Plug Issue: The oil drain plug is used to drain the engine oil during oil changes. If the oil drain plug is loose, damaged, or not properly sealed, it can result in oil leakage. Ensure that the oil drain plug is tight and properly seated to prevent any leakage.
Other Possible Causes: There may be other less common causes for oil leakage, such as a damaged oil line or a malfunctioning oil pump. If none of the above reasons seem to be the cause, it's advisable to have the motorcycle inspected by a qualified mechanic who can diagnose and repair the issue accurately.
It's important to address oil leakage promptly, as insufficient oil levels can lead to engine damage and poor performance. If you're unsure about diagnosing or fixing the issue yourself, it's recommended to consult a professional motorcycle technician for proper inspection and repair.
