Hello,I will be glad to try and assist you with this,Welcome to Just Answer.


Make sure there isn't an old oil filter seal stuck to the housing the filter threads onto as this will cause this issue.If this is o.k. the next likely component to leak and run down like this is the oil pressure sensor right above the oil filter on the oil filter housing,check and see if it is wet with oil and disconnect the electrical connector from it and see if oil runs out,if you see oil anywhere on this sensor then it needs replaced.

If the sensor is o.k. then most likely the oil filter housing gasket is leaking and causing this here and the gasket would need replaced.

Most common is usually a double sealed filter or the oil pressure sensor as I have seen and repaired both.
