cobra upper install problems - HELP!!

blk88lx · 04-19-2003, 07:33 PM

I have a 5.0 Cobra upper and I am wondering about 2 Vacuum connections on the front of the intake.

1. vacuum T on drivers side - 1 goes the PVC Valve where does the other one go?

2. There is a vac port where the T/B spacer would be on the stock intake. What does that connect to?

3. Vac hose off the charcoal cannister (below the air filter) used to go to my stock intake, where does it go now?

HELP! Car running like S@@T!

well you might have to swap the thing that goes into the intake for the charcoal canister hookup, also remember the fpr hookup in the back, someone else might help you who actually has a cobra.

The charcoal canister hooks up to the vaccum port on the intake itself, It would be where the egr spacer is located on the stocker.

Got it.

What about the Vac T on the drivers side lower part of the intake?

ok. One goes to the vac source on the firewall, and one goes to the pcv.

I just pulled my stock intake this weekend, granted it's not a cobra, but maybe it'll give you some idaes.

There's a vacuum line that goes from the the CENTER of underside of the intake where all those ports are to the T on the driver side and the other side of the T went to the PCV...

Also on the center part there was a wierd vacuum tree of sorts, it was a black metal tube that has a right angle and then two smaller tubes that just went straight out... the larger right angle one went to the firewall , one fed vacuum to another vacuum harness over on teh pass. side and the last was the vacuum for the egr diaphragm

lastly there was a vacuum line in the center again that went to the charcoal canister, though it wasnt a straight shot, the line was coupled along the way it was split about where the distributer is. I dunno if it was repair or that was factory...

what's the EGR spacer? did you get rid of your EGR? cause there were no vacuum lines on my EGR unit, only to the diphragm of the valve. there's COOLANT lines that go IN and OUT of the EGR unit.

Maybe Mine's different, but I have:

TB, a gasket, the EGR block, a gasket, intake plenum.

There's a vacuum nipple on the TB but I forget where that's fed from. I'll figure it out when I put my engine back together

The egr spacer is what you called the egr "block". Thats where the coolant runs through. The vaccum line on the tb goes to your oil fill on your valve cover.
