C6 Modulator valve vacuum line routing
« on: June 07, 2021, 07:47:46 AM »
Recently received  my new modular valve vacuum line  and I don't  think the routing is correct, does anyone have a photo of a original 67  GTA,C6 with  a 390

John, I found this 68 but I wouldn't take this for gospel.

It does not look typical on the upper section where it crosses over the dip stick tube.

Took a look but no clear 67 applications to show - only ones from other years but agree it appears the tube is longer than needed producing an extra bend where your tube makes a left turn at the back side of the head.


Do have a few close quarters pictures of that turn area behind the head as mentioned above from the 7R02S car in the Unrestored Picture Section of the site. Hope it helps in some way. To make it somewhat easier to follow. Green arrow = vacuum line Red arrow = Dipstick tube for a couple of landmarks
