Hey everyone I'm new here so bear with me if you can i have an 09 chevy tahoe 5.3 vortec and I changed my o ring on the pick up tube and changed the oil pan gasket and also put a new gasket on the oil cooler lines and my oil pressure isn't reading any better and I believe I've picked up a small leak but can't really tell where its coming from I know its around the back somewhere I can see it dripping off the corner on the passenger side and its on the sway bar any advice on what I should do

 

Might need a new oil pump. What's the oil pressure on the dash? How many miles? You really need to check it with an oil pressure gauge.

 

Oil pressure sensor is at the rear of the motor. It also has a filter below the sensor, and it's known to plug as well as sensor issues.

 

How many miles on it?
