Default Vacuum line identification…

It’s been quite some time since I’ve visited the forum and the C5 is aging. After putting in a clutch, balancer, and all of the other “while you’re in there” items, I’m about to start driving it again and noticed a vacuum leak. I’d like to replace this line but not sure what it’s called or part number. It goes into the front of the intake on the passenger side…




Any info would be aprreciated!

That is the connection to your pcv valve. Unless someone has started reproducing those, they are obsolete. Replace with compatible hose.

Got it, appreciate the insight. Guessing I should replace the PCV valve at the same time, it has never been changed than I’m aware of.
