What is part? Snapped off at entry connector also the hose split. Hense the coupling attempt that I had on hand….but now I lost the little orange thing that fit inside….so ill just buy a new one instead of a patchwork fix…..

thanks

 

Not sure. Is it on the parts diagram link below?
Breather Tube - 2001 Acura TL 4 Door TL (NAVI) KA 5AT (acurapartswarehouse.com)

 

Didnt see it, heres zoomed out pics.

 

Found the yellow part

 

PCV valve

 

I wanna say the item you are referring to might be item 8 in Zeta's post. Is that the PCV the tube connects to in the valve cover?
