Emissions removal

[dsmdeliveryboy]

I know this has been covered tons of times before but I can't find exactly what I'm looking for, I have a 90 Talon TSI AWD and want to remove all the emissions and vacuum lines I don't need etc but I don't know what I can remove and where I can find pics of it or anything. I just want to clean the bay up a little and get rid of the chance of any vacuum hose leaks. Thank you!

This is the link I used to clean up my engine bay vac hoses. I pulled everything out except for the purge evap solenoid, which I left connected (later it will run my cyclone intake control) I did add the a long hose from the gas tank vent line that I ran out the passengers side wheel well to avoid the fumes.

Pretty straight forward. Cleaned up the engine bay a lot, I was surprised by the difference. I had not even dug down to find all the extra junk that was in there before, my car is just now moving away from stock after two years of owing it!

Good luck!

If you don't have a way to remove CELs then you need to keep the solenoids connected.

Pull the charcoal canister but leave the large line hanging with the check valve in place. Remove vac. lines from solenoids and where every they attach too. Cap off nipples on TB and route the vacuum line that goes IM-->FPR solenoid-->FPR to IM-->FPR

Why do you have to leave the check valve in place?

I made this mistake so just wanted to say dont cap off the little metal hose that runs on the firewall to ## canister. its a breather for ## gas tank. some people loop it down so then no water can get it but i didnt.

If someone could post pics of their bay it would be greatly appreciated, I don't want to pull hoses and then have my car running like ass with CEL's left and right .

thats my engine bay with all the extra vacuum lines removed. It is set up the same way the taboo speed shop diagram of race application is set up (except my catchcan setup is a little differnt.)

My TB is all plugged off.

Running one line from my intake manifold to my BOV

One line to the brake booster

One line to the Fuel Pressure Regulator.

My boost source comes from the j pipe, and is connected right to the wastegate.

One line running from the Valve cover to the intake mnifold, with a catchcan and check valve in between.

One line running from the valve cover to the intake pipe tot he turbo with a catchcan between.

TOTAL -6 vacuum lines total

I'm running my mbc t'ed off my bov because my J pipe did not come with a nipple, and I'll be running my pcv to a catch can and then a filter on the catch can because my intake pipe has no sources for vacuum lines. What is the thick line going into the stock intake pipe on the 1G intake? What do I do with that? I'm gonna need to look at the diagram again, its been awhile since I've checked it out. And what about the vacuum line on back off the valve cover?

What is the thick line going into the stock intake pipe on the 1G intake?
- The thick line, about 3/8 inches I think, is to the brake booster. Leave that connected.

And what about the vacuum line on back off the valve cover?
-The line that is in the back of the valve cover, and not the side, is the PVC line. I hooked it to my intake manifold with a catchcan and a check valve in between (check valve between the intake manifold and catchcan).

I thought the PCV was on the left side of the valve cover?

no, if you are looking at the engine bay on the front of the car, there are two valve ports. The one at the top is threaded and has the ability to have a pcv valve inserted.

The one on the left has no valve for one way travel. It is just a provision for a vacuum line to be attached I have it running to my intake manifold, but have a catchcan to gather the oil.

In my current set up I am using the pcv valve, catchcan and check valve.

When a engine is creating boost, the pcv valve does not allow for the positive pressure of the manifold to leak back into the pcv valve. When your engine is in vacuum it draws air from the valve cover.


I ALSO RECOMMEND NOT USING VACUUM LINE FOR THE PCV SYSTEM. IT WILL BLEED THROUGH THE HOSING.

O I see what you mean, so what should I use for the hose then? I already bought a oil catch can that uses vacuum lines..

 

[agentorange313]

oil resistant hosing, the same hosing you would use for your you oil cooler.

O ok, and I could just find that at a auto parts store? Or should I go a industrial supply to find it.

 

[agentorange313]

u can get it at any auto store autozone etc.

It might tell you if it is oil resistant on the hosing. I think fuel line hosing will work. I have one of the line is fuel hose since I ran out of oil resistant, and it hasn't bled through. Can anyone else confirm this?

 

[dsmdeliveryboy]

I need to find something to do with the thickest line going to the stock intake because I'm putting on a intake with no vacuum ports and that needs to be gone Lol
