Finally *fixed* the vacuum harness

Here is what's left of what I DIDN'T USE!! :eek: I actually re-used the separator/PCV setup and put a K&N breather on the other side of the PCV grommet.



Does anybody know if both nipples on top of the T.B. are full vacuum/boost? I know the 8v and V6 T.B.'s had a port on there that had no vacuum.

Oh BTW...everything works. The only thing is I now have a manual boost controller and lost the purge canister function in the melee attack on the harness. :D

whats to the right of the oil cap? Is that for the intercooler hose? I see your AC foam is cracked. Can you just tear it off? I'm guessing its there for a reason :(

To the right of the oil cap is the intercooler pipe...I didn't have the turbo-to-intercooler tubes ON in this picture sorry.

Who here actually has that A/C line cover foam intact?! :confused: It's just an insulation for the pressure lines. I do intend to re-cover it.

Man this picture makes the engine look dirty...it's quite clean in person.
how do you recover it? Do they sell the foam? I hate that its all ruined. Any tips for someone on replacing vac lines? I have no idea what I'm doing :( Do you use zip ties or what? I was going to find the lines where I can find the ends to and put a new piece in for everything. You buy the vac tubing by the roll anyways :)

BTW, that paper filter looks kinda sad :(

That picture is a night and day difference between the picture from when you bought the car. :thumb:

I will soon be redoing the vac harness on my car. Did you get a vacuum distribution block? What did you keep hooked up?

Thanks,
Ryan

Man you're just FULL of kind words today...

The foam you can do without...I imagine it's used as an aid to keep the *sweat* from dripping all over the engine bay.

Replacing vacuum lines is easy if you have a few good *sources*. I prefer not having a single T...all separate lines.
Thanks for your help :)
No more dusty engine bay for you ;)

Why thank you! :thumb: The airbox assembly will soon be removed and put in storage in favor of some flexible silicone intake tubing for the turbo with a cone filter in the nose of the car. Ok Tudds? :D

I WAS going to get a vacuum block before I realized the R/T has like 7 great sources. (2) vacuum/pressure on the front of the intake that are no longer used...(2) vacuum/pressure on top of the throttle body...(2) pressure sources on the turbo...(1) intake vacuum/pressure source at the brake booster that T's to the cruise. It's GREAT once you get all the CRAP outta the way! :D

The following are the only pieces that are no longer functional..the wasegate and purge solenoids. The lines that snake across the fuel rail split down to the front of the intake and across to the purge and wastegate solenoids. Those (2) were removed in favor of manual boost control and eleminated purge circuit. Everything mechanical is still in place and could be functional again by installing a few vacuum lines to the solenoids.

I literally took 3 days studying the routing of the OE harness so I could get it all straight in my head before diving in. I'm a smart guy by most accounts and this setup had me licked for a few days...it's THAT redundant.

So after ripping it completely all out of the car...I was then able to see how many sources I had and how easy it would be to get everything I wanted working again.

AFPR hooked up, cruise hooked up, source for HVAC never touched, MBC hooked up to one of the turbo sources, MAP sensor source never toouched, and that's about it.

I had to buy a bunch of rubber caps to cap off a turbo source, the purge line back to the tank, (2) intake sources, and (2) fittings on the airbox. PHEW!

Now that the leaks are all fixed I can focus on other areas that need attention. :thumb:

Looks Clean Chris, might want to leave the line back to the tank vented though.

When I went to put gas in the the car 2 days ago I noticed that there was a ton of pressure in the tank...so I left that tube vented/open. :thumb:
Or you can just run your boost gauge off the gas cap :p

Or how about using it as a cheap rising rate fuel system ..for every pound of boost = a pound more pressure in the fuel system. :D
