i have an oil leak that started last week when i started driveing my truck after a transmission change. i thought it was my filter at first and i replaced it and it still is leaking. the oil is running from the front of my filter around the top and down the back side of it and is a steady drip. on my trip home it went through a qt of oil and it was a 130mile trip and it only leaks when its running. any ideas???
