whats this?

the hot side by the maf?? Do you mean on the air inlet tube? If so, that is the breather line from off of the valve cover.
"hot side" usually refers to the charge piping between the turbo and the inter cooler. That is unless you have a maf relocation charge pipe set-up. In that case we're talking to different things here

LNF turbo setup on a L61? No ****, that's pretty cool.. Sorry if I had misguided you then. I didn't read your sig and assumed you just had an LNF.. Dayta is most likely right about this one then. Do you have any pics so we can confirm it?

im actually an LAP... but same difference... im so confused with this thing... i need someone to take pics for me... of where the pcv line on the turbo goes. and the thing i was just asking about i will have to loop around to the front of the engine where my valve cover vent is.

I'm not sure if it helps any, but I have a parts drawing of the LNF turbo/exhaust manifold setup in my pics section that you can reference if it helps any. If you need any other drawings I can see what I have and post them up for you. Unfortunately without pics of your setup, I can't give you an accurate answer to your question but I'm guessing like Dayta said, it's probably vacuum, bypass valve, or recirc related

i have that blown up and printed in a poster lol... but i need to know where the bpv hose leads to. i thought it went to the nipple i asked about and the pcv line went to the valve cover. but thats what i get for thinking
ok im not positive... but if you use an aftermarket bov you just connect it to the nipple on the intake manifold. does the factory bpv just hook to the intake manifold and thats it?

the bpv should go to a good vacuum source off of your intake manifold.. you might have to get a tee fitting to make that work.. I assume you're not going to be using a bov? Also, are you somehow bypassing the solenoid which controls the waste gate on the k04?

ok nice.. Jesus the server is being slow for me tonight.. That's funny how you answered my question via an edit while I was waiting for my last comment/question to post
#16
yeah its really slow for me too... my cell is faster than the computer. but do you have a diagram or a picture of the front of the engine without the engine cover? all the google pics have that cover on them. but the bpv makes no sense to me.... how does it recirc if the vacuum from the intake pulls it open? where does the extra pressure go to?

Basically instead of releasing access boost atmospherically like a BOV it recirculates the blow off into the intake side of the system and reuses the air.
I am loading a parts breakdown for you as we speak. Hopefully it is usefull.. If not then I can take a pic of my motor for you if you'd like

pretty much.. and with a cai you get that bov pssshhh sound that comes through the actual cai.. not quite as loud but it still sounds cool. The breakdown is loaded if you want to check it out. It might be a little on the small side so hopefully you have GREAT eye site.. lol

sorry for the delay.. I'm multitasking over here..
The PCV goes directly to the valve cover... that should be in your exhaust side parts breakdown that you have a blown up poster of actually

The nipple on the inlet tube is for routing fresh air to the crankcase for the PCV system. The hose that connects to it runs to the valve cover. The LNF valve cover has a second nipple with a hose running to the inlet of te turbo. If you have a vent on the front of the valve cover, you could run it to the turbo and plug the nipple on the intake tube. Otherwise, plug both of them and put a small breather filter on your valve cover vent tube.

awesome thanks matt! i pull plug the small nipple and run the hose around the engine to the turbo pcv nipple... seems the easiest. i think i have it all figured out now. i hope anyways.
thanks for all your help and the picture. if i have any more questions i will send you a pm if thats ok? but before i go to bed... i talked to psychocam and he tapped a vacuum nipple on the intake manifold... should i do the same? or can i get away with using the evap or brake booster line?

You can drill and tap the manifold if you want to go that route. Whether you tap off of the mani or branch off of an existing line just be sure to be as far up in the vaccum stream as possible (closest to the manifold).. If you can't tee off of something then the brake booster works as well, seeing as how that HAS to have solid vaccum.
