I had my 300D stored for 3 months. I had left a clean piece of cardboard under engine bay because I had seen some drips. When I got back, there was a large area on cardboard where fluid had soaked in. I renewed the cardboard after driving the car and left it overnight. There was a new small mark. Not engine oil which would be black. It is a light fluid, so could be transmission oil or diesel fuel. It is dripping off middle of cross member just behind engine.
There is a transmission cooler line that runs above the cross member. I moved one of the clips and the tubing (copper?) is deformed. Not sure if it has a pinhole. There is another clip further back but it seems tight and too far back to be cause.
I was thinking of removing the line. Replacements are quite expensive and it seems a dealer only item? (Parts 1232704096 and 1232703396) US$122 each, probably double that in C$.
Has anyone attempted a repair on the wear spots on those lines? Thinking I might be able to clean thoroughly and apply a solder or epoxy repair? Then install new grommets under clips.
Source of drip may be elsewhere, but the wear spot needs fixing one way or another.
Here are pics of the line wear
