Acura TSX engine oil leak issue after gasket replacement on Acura TSX

Problem overview

Some Acura TSX owners report experiencing engine oil leaks after a gasket replacement, often attributed to several key components. Issues may arise from the VTEC oil system gasket, which is a common source of leaks if not installed correctly. Additionally, the VTEC solenoid gasket can contribute to oil leaks, necessitating a double-check of its installation if problems persist. The valve cover gasket is another potential culprit; if recently replaced, it should be inspected for damage or improper installation. Furthermore, oil leaks from the front main seal can be misdiagnosed as gasket issues, making it essential to ensure the seal is intact and properly seated. Lastly, some owners find that the VTC strainer and its gasket may also be responsible for leaks if they were overlooked during the gasket replacement. Addressing these components thoroughly can help resolve the oil leak effectively.
