I have a 1995 Toyota Camry with a slow freon leak. I can see the oil exiting from the vertical section of the foam rubber insulation that surrounds one of the aluminum freon tubes. It is the tube that runs across the car along the bottom of the radiator. The leak is visible exiting the rubber insulation at the vertical section on the drivers side of the car when it goes to the receiver dryer. There is no joint or any other feature that would be a likely cause for a leak, just a bend in the tubing. The tubing is covered with the rubber insulation so it is hard for me to locate the exact spot. Right now the leak is relatively slow and I can probably just put in a can or two of freon each season. Fortunately it is R134 which I can buy.
My guess is that there is a pinhole at the bend. Have any Toyota experts seen this before. Is there a way to repair the tube or do I need to replace it?
