Outkast, you totally have the wrong idea, my comments were not directed to you, but to VegasZ....he was saying this:

As you can see I obviously posted that the line from the elbow to the opti was intact......He just posted this useless information for fun i guess. Thanks for all your info though, I understand how the system works now.

As of now the vacv line to the manifold is plugged with a vaccum cap which is on the 2nd blue restrictor thing...is this ok? Is it alright to leave the vac port on the intake manifold plugged permanetely?

 

Actually, he is not wrong and it is quite relevant to your scenario.

By capping off the vacuum line going to the manifold the flow will reverse unless you have capped off the opti or the vacuum line going to the elbow. If you run a MAF sensor in your car this will allow unmetered air into the motor and it could run a little rough. This would be the case with any kind of vacuum leak so it's not due to the opti messing with your timing or anything.

I would suggest either capping off everything
[list=1][*]Remove vacuum lines[*]plug hole in elbow with something that's not going to get sucked in[*]cap both vents on the opti[*]cap the nipple coming off the manifold[/list=1]

or fix the system so that you can hook up everything.

By doing this you will be running a non-vented opti which will not last long.

 

Even worse, he's running a non sealed, non vented opti. Might as well dump a gallon of coolant on it just for S & G's. And on a side note, unplug the MAF and see if you have a performance difference. This will eliminate the unmetered air after the MAF and therefore in a sense your car will be running in speed density mode. But this does not save you from the fact that you have an exposed opti core. Good Luck

 

Yeah..I know this sucks. But what can I do with the port broke off, I tried gluing a vaccum 90' fitting in there, and it felt perfectly sealed, and with the epoxy it should have been even better, but it was obviously causing a vac leak to the intake, cuz when i plug it of its much smoother, I giess I'll just plug both and wait it out and see what happends. I'd like to have a new opti anywayz so for once I can actually hook up all the lines correctly.

Thanks for the help guys.......
