Hi all. So we found that a lot of the leaking oil in my Malibu is coming from the oil pressure sensor next to the distributor. I am stock using the idiot light only. The gauge seems simple enough, unscrew from the block add a bit of teflon tape to the replacement, then attach the rubber cap back to the electrode post thing. Of course I didn't have a tool that could remove the old unit and ordered it on amazon. However I didn't replace the rubber cap on the unit when putting things back together. I drove to the store and saw a line of oil from the garage all through the alley. I put the cap back on it and change the oil and filter. Only about a quart and a half of oil left in the car. a lot of oil lost in a short time. My question is I thought the basic sensor was just electric and not mechanical. So does this sensor actually send oil somewhere or was the cap acting like a tournakit and lessening the oil being spewed out. I have enclosed a picture of the sensor that I just purchased.
