Weird deposit in my car

[Moustachienne]

Hey,

Disclaimer: disgusting picture coming up.

So I found this weird oily/fatty/waxy deposit under my car hood. It smelled weirdly of old cheese or something related.
I’m guessing some slow leak between those two tubes?? Any idea what it is and can I continue to drive for some weeks when I’ve got a checkup scheduled?

I know it’s my own responsibility

Thanks

Maybe some animal deposited a piece of cheese that it found somewhere under your hood for later use.

Just remove it, most probably there is nothing under, no corrosive impact, in which case your concerns are immediately settled.

Clean it and watch if it is coming back
