Hi guys, I was checking my transmission fluid the other day (engine running of course) and noticed one of the rubber hoses in the engine bay looked like it was 'sweating' a little. There didn't seem to be any direct leak, just very small droplets sticking to the outside of the rubber hose. I wiped it down with a tissue and it didn't smell like gas or look like oil.
Can anyone tell me what the hose in the picture under the arrow is?
I know hoses deteriorate over time and I plan to have it looked at. Is this something I should be immediately concerned about?
This is a standard pic I got from wiki, but my engine is the same. eg NA 3.8L
