On the valve cover side, not really. On the ICV side it is open to the intake so it would result in a vacuum leak if left unplugged.

I get the vacuum leak part. But why plug everything up? Why not just connect everything with new line?
I'm just curious
-
Personal preference I guess. I don't think that tiny line is doing too much. Especially if you are just VTA
-
On obd1 the large line goes to the intake elbow before the throttle body. Obd2 it goes to the cyclone cannister thing and then to the dipstick tube. You could put a catch can between if you dislike oil in your intake manifold. I just giver, more lubrication hurts nothing.

If there isn't a vacuum issue with them being unplugged I'd rather not get oil everywhere. I've ran out of harbor freight rags as is.

Added oil & put a new belt on.
I still need shorter bolts for the crank pulley, I just wanted to see if the belt was correct. It was.

If you leave them disconnected you will get some oil coming out of the end. If you plug them you will build crankcase pressure and oil will come out all of the seals. Sounds like a catch can is your best option.
Also that looks pretty!

I'll most likely end up running the larger line to a catch can. Since the smaller line is brand new, I'll most likely keep it plugged into the line on the ICV. If it gives me issues, then I'll cap it off
-
That will cause a vacuum leak
Will it cause a big enough leak to be an issue? Not sure. -

What will cause the leak? Running the lines to where they need to go?
Or capping off the ports on the smaller PCV nipple and the ICV nipple?
Or was that regarding the catch can for the larger line
-
Woah, triple post!
That would be with an atmosphere venting catch can on the large line with the small line hooked up to the connector behind the throttle body. -
So if both go to a catch can and the ICV nipple is capped. It will be good to go?
-
Yep!
May I inquire why you are venting the catch can to atmosphere instead of plugging it back into the intake boot? -

I probably won't. I was just curious really.
I have some barbed connectors in a shopping cart waiting to be ordered.
-
Harness is now (kind of) on the s50
That's about it
-
Looking good
-
Is it done yet?
I'm at that point where all the parts I've ordered are currently installed. But now I have to make another order for more crap
-
Left to order:
Clutch/PP/FW
Slave cylinder
driveshaft
Giubo
O2 sensor
Random barbed connectors to bypass coolant lines to TB & to route the PCV line to the bimmerworld intake elbow
Vac line from fpr to intake manifold (may be able to reuse mine, unsure if long enough)
Figure out what to do with purge valve
I can either vent to atmosphere with that line from the tank, cap off the nipple on the TB and just keep the sensor connected to the purge valve (?? Will it throw a CEL) or just run the hose from the tank inline with the purge valve and plug it into the TB (essentially just bypass the charcoal canister thing) and keep harness plugged into purge valve.
If I do the second option I'm not sure if the purge valve still even works so it may just be better to vent to atmosphere.
