SO, I removed my vaccuum lines...

[Jiggalude]

Alright, so I was removing some vacuum lines from the car and I'm curious now if I did it correctly. I removed the ones from the top of the TB and capped them. Now the four lines ran to other vacuum sources on the car, so I pulled the hoses off and capped those spots as well. There were four nipples down underneath the intake manifold. There were also two on the passenger side of the intake manifold. And I also removed the lines and capped the nipples on the little black canister underneath of the battery. The car runs fine, and I'm assuming this is correct seeing as how the lines ran from the TB to other locations on the car.

Sounds like you got most of the emissions stuff. depending on your situation and possibly you mi9ssed it but you should have also blocked off the egr valave on the intake manifold if you wanted to. But that will throw a CEL without mod. No need to worry about the hard lines under the intake manifold, they are just bridges for your soft hoses, silly really. if your doing an emissions delete you can take the charcoal canister (under battery box) right out too.

You only should have two vaccuum lines actually running off the intake but that also depends on your setup. Basically the BOV and FPR need vacuum/boost. I use the top tb ports for my boost and vac gauges.

Ok cool thats what I thought.

block of the EGR or that will be a nice boost leak for you!

I broke one of the nipples off the charcol canister when I pulled my motor, can I just cap them off or do I need to do more

 

[Ghostriderdsm]

Are you gonna delete emissions?

If so Just do the vaccum elimination process and you can pull the charcoal can right out!

I havent thought about it, if thats the easier fix with out causing other problems other than a cel. I dont have emmissions testing here.

Yah. it's REALLY simple and it cleans up your engine bay lots and cuts down a possible boost leak source.. Just remeber to do a EGR block off!.. That diagram is pretty retard proof.. but let me know if you get lost.

 

[docb002000]

cool thanks i printed off the diagram, I was worried about finding another canister set up. I am getting ready to put the motor back together, so basically it will get rid of all those little line on the back of the intake? were can I pick up the block off plate?

 

[Ghostriderdsm]

You can make one out of a pop can or there is a place that sells them.. Just search egr block off plate.. should get some information

I believe your supposed to leave the line running under your battery uncapped. Just as a back up if your gas tank goes positive pressure. It's a pressure relieve hose running all way from gas tank. When pressure builds up it release's the gas fumes back into your intake. Not sure what the results would be with pressure build up in your gas tank. But the relieve was built in for a reason. It's ok to dissconnect it just I wouldn't block it off. I left the tube running from firewall running into canister but removed all tubes running from canister. You do how ever wanna make sure you block off the hole on the intake tube.

A +1 on the EGR block off, will give you a nasty case of idle surge and be a leak. If your running the stock boost control solenoid then all you have to block off are the ports on your throttle body and the one larger hole on intake from the charcoal canister. All the others you can leave uncapped. If your running a Manual Boost controller then your gonna wanna also cap the nipple on your J pipe also the one right behind your air filter box.

GL I did mine a few months ago and fixed alot of issues with the idle. I'm figuring I had some leaks somewhere and my EGR valve was nasty almost completely clooged with debris.
