Lets play name those lines!

[19Cutlass94]

So I have these lines here, appear to be vacuum lines/pcv lines, but I actually have no clue what they are for. Anybody care to help me out? Im almost certian I wont be needing them, but would like to know what they hell they are

I'd call the one on the bottom Robin, and the one on the top, Stephanie. As for where they go, I have no idea.

[ScoobyDoo82]

My guess is that they have to do with the EVAP system... I'm not aware of any solid vacuum lines that are that thick.

[19Cutlass94]

Are they DOHC specific? I know Ive never seen any like this on a pushrod

[ScoobyDoo82]

Now I'm only taking a wild guess, I couldnt say for sure. But seeing as how the evap lines have to run under the car from the tank to the purge canister I'd assume they'd be made out of those type of hoses.

I believe they belong on an LQ1

[GOT2B GM]

the top line is 91-93 LQ1 PCV breather line from the front cam cover to the rear cam cover.

the bottom line is 91-93 LQ1 PCV line from the crankcase valley plate (under the LIM) to the PCV valve near the TB
