Ive been having some issues on my 94 LS recently and i found this broken line next to cylinder 1s plug wire, can someone tell me what this line does and where i can find a replacement? Thanks
Hey thanks man, i found the part and got it installed and it fixed all the issues i was having! 🤙That is the check valve for the vacuum lines that give vacuum to the EGR system and the VRIS system. They are plastic one way valves, very cheap, like $ 5. You can get one like this or very similar at the standard auto parts stores. Just be sure you install it in the right direction.
