Chevrolet Impala oil leak on passenger side after replacing oil filter adapter gasket on Chevrolet Impala

Some Chevrolet Impala owners report experiencing oil leaks on the passenger side after replacing the oil filter adapter gasket, which may stem from several potential issues. These owners have noted that improper installation of the gasket can lead to leaks, emphasizing the importance of ensuring it is correctly seated and tightened. Additionally, some have encountered problems with defective or damaged gaskets, which necessitate replacement to resolve the issue. Loose fasteners around the oil filter adapter have also been identified as a common cause of leaks, highlighting the need for regular checks and tightening. Furthermore, owners have found that cracks or misalignment in the oil filter housing can contribute to leaks, requiring replacement of the housing in some cases. The condition and installation of the oil pressure switch near the oil filter adapter should also be verified, as a faulty switch can lead to oil leaks. Lastly, some have noted that ensuring the oil cooler lines are secure and undamaged is crucial, as leaks from these lines can also result in oil dripping onto the passenger side. If the oil leak persists after addressing these issues, seeking professional assistance is advisable for further diagnosis and repair.
