Oil leaks

With it dry, I wanted to confirm the leak is from the clamp area. I went for a 10 minute drive. Came back, put my hand on the underside of the oil filler tube clamp....all dry. Next few days, still all dry.

Then today, I went for a longer drive, revving up to redline a few times. Afterwards I did the same test (felt the underside of the clamp). However, this time it was...damp. Not enough oil to form a drop. Maybe only 1/4 of a drop. No CELs. Some mechanics told me I would get a CEL if there was a leak on that tube because of the loss of pressure. I'll talk to my local indy mechanic eventually.

On another topic. I noticed two hoses was fusing into each other. See pics below, pics are taken after I separated the two hoses from touching. What are these hoses? Check out that indention on the bigger hose. Anyone experience this before? Is this a real concern?

It could be that the source of the oil is when oil is added, with very little being pushed out during running. I had a filler tube that was cracked at the bellows and oil all over the right side of the engine and the engine compartment. It must of lost 10% of any oil added via the filler tube.

On the other topic. The top "tubes" are the shifter cables, they are supposed to be connected. The tube underneath in your red circle is for the air conditioning. If it is rubbing there you might add some rubber between them.

Did you get a CEL for the filler tube leak? I'll experiment adding a little bit of oil through the tube and see if it leaks. How did you address your issue?

Thank you for explaining the tubes! So great to have knowledgeable people on forums. The shifter cable was resting on top of the air con tube. Where you see the indention on the air con tube is where the shifter cable was touching. I just pryed it off and took the photo after.

There is no OBDII codes directly linked to the oil fill tube.
But if it had a big enough hole in it....that could trigger a vacuum leak code..
Something like the P1128 and P1130 codes.
