Ok. I am wondering if I can drive the car with the dipstick unplug (with the dipstick pop up a little off the tube) for a few days. The theory behind this is I want to see if it will release the pressure in the crankcase and stop the oil leak from the rear main seal.Nothing wrong here. When you remove the dipstick you’re creating a vacuum leak which would cause a lean fuel trim.
Question. Does the air always suck in through the oil dipstick tube or the oil will spew out under normal driving conditions?I can’t speak to your theory but I know about fuel trims.
I was driving my car for several days with the fuel trims in the high 30. Your CEL will trigger if you go above 25.
it’s generally an idle only issue as when you drive your air will increase and not create a vacuum.
