Hey again lol...

I'm onto making sure all my vacuum lines are correct and functional. Is there anywhere or anyone have a comprehensive vacuum diagram for all the vacuum lines including the turbo and wastegate and have the specs on how big the vacuum lines are supposed to be? I have looked everywhere and can't seem to find a suitable one. I found one for the ac and heater lines but not any for the engine vacuum lines. Am I missing it somewhere? I want to make sure all my lines and checks valves and anything else related to the vacuum is good. Can someone point me in the right direction for such info please? I seriously can't find any solid references for this. Thx.

Thanks for the help... however I am more specifically looking for the routing of the hoses around the turbo and the wastegate with the y connection and that area. Is there a diagram that shows all of those connections along with the others? Am I just missing something? Or is it a secret? Lol

Ok. I have seen this too, but I want to see how and what alllll the lines connect to. I think i am missing a hose or two and even may have a few in the wrong places. The car was in a body shop for a long time and i am trying to get it sorted...

There's a guy on here that has a gazzilion vids on these cars. He left a link for his Youtube channel before for you. Maybe he has one on vacuum lines. I think he's in Canada...so you could even call him...for free.

Thanks guys! That's more like what I was looking for. I am gonna go work on the car (gonna do a tranny fluid and filter change (will make a separate post on that) and I will look at the vacuum lines too. Gonna check out the hoses and see whats what. And yes. I have watched a bunch of your videos and they are helpful. Will post back and let you know what I find.
