2001 Oldsmobile Aurora L47 4.0 L - On the same car, with the 4.0 L V-8 engine, I believe my son put too much oil in the engine. I think this caused excessive oil pressure. He now has an oil leak, basically streaming out while the engine is running. It is not coming from the oil filter nor is it coming from the oil pan plug. It is not coming from the oil pan gasket. It appears to be coming from an area obscured from visibility due to the exhaust manifold being in the way. I am wondering if it is coming from the seal that goes around the dip stick housing. What do you think? He had changed the oil himself.

The dipstick tube's seal or even oil pressure sensors might be in that area where the leak is coming from I think.

 

update: I found the leak using a snake camera. It appears to be a sensor that is right above a metal bracket. The metal bracket is part of the engine mount and it is also connected to the oil pan. Above it is a sensor that is connected to a metal line that goes right to the oil filter. I will attach some pictures. The snake camera pictures are not great but I was able to see the oil streaming out of this sensor while the engine was running. I would like to confirm that this is the oil pressure sensor.

disregard the datestamp in the picture, i dont know how to set the date on the snake cam.
