Once again im stumped and cant find in the haynes manual what this opening does. i dont want it to be gas or oil and have it chucking out **** and destroying my engine.

So if anyone can please tell me what this is...you get a million internets.

FYI it's by the oil neck on the passenger side. A little bit lower than those lines that lead to teh rats nest and next to he oil filter.

 

PCV connection.

 

it's for crank case ventillation.

not connected properly will cause lung butter.

 

where does it lead back into?

 

I think It goes back into the Intake manifold.

 

It ventilates the crank case and connects to the PCV valve that sits right above it (which I don't see in the pic). Its a black round looking device. Check for a vacuum nipple above the one in question on the filler neck (It looks like you have an N/A from the filler neck). Is that capped off? If you have emissions removed you will want to cap off the lower nipple (one in question) and use vacuum tubing to connect the top nipple to a catch can to catch any oil that is comes out. If you plug both of these pressure will build up in your crank case resulting in your engine smoking. That or hook the stock PCV system back up and route the lines correctly per FSM specs.

Thats really wierd, my oil neck is on the drivers side....whew....

 

RETed would probably be the one to know for sure.. But I didn't think there were any 13B's with the oil kneck on the passenger side.. Unless of course it was a JDM RX-7.

 

sorry. i was **** tired when i wrote that. it is on the drivers side. i dont know what i was thinking.
the engine is a jdm t2 btw

 

I think i took the picture at an akward angle too. the left part of the picture is towards the front of the motor

 

I just cranked it. started fine. and cranked lung butter it did .........

 

Just hook the PCV back up so it can route fuel vapor (charcoal canister) and crankcase emissions into the intake tract. It's not going to be pumping anything solid into your motor, that's what the PCV is there for.

 

It's a fitting for emissions.
It will normally connect to this thing called a purge valve.
All the purge valve does is suck fumes from the "crankcase" back into the motor so it can be burned - pure emissions.
Leaving it uncapped should not affect the way the engine runs.
The only thing it might do is cause a mess on that part of the engine when crap and maybe some engine oil leak out due to spirited driving.
If you're using a catch tank, cap that fitting and use the fitting at the top of the oil filler pipe...at least this is for turbo engines.
I cannot confirm if non-turbo engines are similar.

Well i got that fixed. But as always another problem arose. I got the car started.

Once again this is a jdm swap. And when I started the engine, I let it run for about 4-5 mins and while i had it on it was idling at 4.5k and slowly worked its way down to 3k. It didn't look like it was going lower than that. I drove it down the block and then back into the parking spot and noticed another leak. Not from the problem previously fixed but on the other side by the turbo. I turned the car off because it was filling the streets with smoke. (Possibly from not being started in a while?) Mind you the engine was not overheating or anything.

So After I shut it off I looked at the turbo side and there was oil everywhere. I haven't gotten under it yet to look for any missing hoses. But my question is...
Is it usual for it to leak into the first part of the exhaust? (downpipe?) Because when i took off the exhaust, there was just black grimey oil. (Hence the smoke) Is the turbo done? When I had the engine out, the turbo had very minimal play whatsoever. If any at all.

So two more problems before i have it working smooth...(Yeah right?)
Well maybe three.

Heavy Smoke?
Leaky Turbo? (anything i should double check?)
And Ungodly high idle?

Any Ideas are greatly appreciated.

 

Ok to follow up on everything that has happened...
I got the idle fixed. It's still ungodly smokey as hell. Not as bad as before though.
It was just a matter of a snagged throttle cable. So now at least it idles at 1k.
Sometimes it dies though. Might be a vacuum leak. I'm not sure.

I'm going to go ahead and take back the leaky turbo problem. I think it might still be leaking a little but...I think i have a bigger problem. So the lung butter went from spewing out from the pcv to now the charcoal canaster on the passanger side.
I'm attaching pics on this post. But it looks like oil is spewing out. I thought only fumes from fuel are suppose to come out. I could be wrong. Can someone elaborate?

Here are some pics

 

The second most prominent problem i'm having is the brake booster. I have this line that's coming out of it and goes across the engine bay over to the passanger side. But the line isn't connected to anything. I think this may be causing the lack of brake power. i mean literally i release the brake pedal just a little and it rolls. The two may be related but I still need to find where this line goes.

Here are two more pics of the hose in question.

I'll upload the video of how much smoke is coming out later on tonight. Once again any help is really appreciated to get this 7 off its wheels and fully functional

 

You really should start another thread, and / or start a thread with a more appropriate title.
You're now getting way off your original title topic with all the additional questions you're asking now, and people are not going to click the thread anymore.
