    I documented the vacuum lines from tearing down my motor if it helps anyone.

    Well done. As an Australian CitroŽn DS19 long distance racer said (after racing one around Australia in the RedEx trail in the late 50's

    "If this #$4%6 @%^&87 it had another tube, you could #$4%6 breed from it...."

    Same applies.

    It worked. It's all back together and ready to go in the car.

    Wow, nice neat work! Love the originality.

    Way more than our 2.8 had!

    Great. Got video bookmarked.
    These engines have some 'Italian' added to them- spaghet..

    What we gonna do with our rusted oil pans ? Have not seen new stock replacements.

    Even more fun is coming removing/reinstalling the turbocharger.

    After rebuild, never got all that hose stuff back on, even though i marked everything.
    Figured memory and tags would work. Wrong.
    Found diagrams help, but pictures of parts are required.
    Not much info on internet. Most 2.3T gone or modded.
    Lots of info in shop manuals. Lots of data gaps too.

    Of importance are tees, routing, check valve orientations, carb, manifold connections.

    Mine actually drives fine without the a/clnr, egr parts.
    Still have all of it stored. The puzzle is not finished and may never be.

    Runs real close to what it ran like in the 80s.
    Mpg, power, torque, is better now. Steady idle, vac.
    Starts the same as always. Pedal it to keep it running when cold.
    Choke never really worked.

    The vac array on the fender is gold.
    Never found out how to duplicate or match any of the parts.

    Noticed intact turbo heat shield.
    Mine broke at one of the mounting points and rattled.
    Removed and awaiting repair. Only been 20 years.

    Seems i recall heat shields on the down pipes near the oil pan.

    That's funny! Luckily for me, pretty much everything was intact! The time gap between said documentation and reinstallation still made things challenging!

    Default matching words and wisdom to carry out plan

    It was all about my wording on wire tags.
    Tags allowed more room to write than tape.
    Had no digital camera then. Now use one to document everything.
    Final engine dress came years later after tear down.
    Could not decipher what i wrote.
    Car did fire right up first try after rebuild without many of those connections.
    And with a official reman Holley 5200 that Holley miss calibrated internally.

    Am always tweaking things seeking sweet spots.
    Years of trial and error with vac connections and tuning were valuable learning experiences.
    Changes that did or did not affect another. What worked and not.
    Carb venturi drip after shutdown in hot weather, no boost, high/low fuel mileage, idle vac readings, flat spots.

    Engine now gets 20-27 mpg. Stock was about 17. Have not had to change anything for several years.
    More power, smooth up/down rpm load-no load. Good torque will pull floored from idle in higher gears.
    The lowest boost starts is at 1800. Regular 87 fuel, 4-5# boost.
    Engine likes 1100 rpm setting no load. Drops to steady 900 with everything electrical running (70a 1G large alternator).
    Entire choke assy, flaps, are completely removed. Starts in any weather as always.

    The weird one is the rare no boost after parking for a bit in the summer.
    Boost option back after few hours.
    Finally found out how to fix that couple years ago, after 30 years of what the heck.
    The smaller vac hose to waste gate somehow gets pressurized.
    Engine off. Pull hose off; psst, air comes out. Reconnect. Good to go boost again.
    Is a mystery to this day how or why it gets pressurized during regular driving.

    Was really frustrating when this happened at the 1984 MOSEM event in Dearborn MI..
    Mustang turned 20 years old. Ford people everywhere.
    Annual show and rare Mustang only parade from FWHQ onto their test track a mile away.
    Was a non-member, but having the only 79 Mustang, got to join in for 20.00..
    High speed runs allowed on the track loop.
    Dang. The no boost event happened. A turbo pony/dog combo.
    Was so frustrated did not participate in the 20th anniversary photo of all Mustang years on the track lawn.
    Was told that photo was eventually hung in a Ford building nearby.
    All years, 1964-1984. Except 1979. Photo is missing the only 1979 Mustang that showed up.
    Mine.

    One of these years, if and when they do that type of photo again, hope to correct that bad decision.

    Super job Gregpro50! I have a few loose ends on mine to sort that lost labels or were never attached when I picked it up (plus I took vids/pictures that disappeared when I dropped my iPhone in the ocean!). I have a few books and schematics that I'll need to consult to figure out what the heck all these valves are for (most say what they are in the diagram but no picture to figure out what it looks like) and only then can I try match 'em all up. Can you make another video but this time make it for CA specific vehicles?!

    DIST – Distributor
    EGR – Exhaust Gas Recirculation Valve
    IVV- Idle Vacuum Valve (Thermactor)

    PURGE CV – Purge Control Valve
    SA- FV – Separator Assembly- Fuel Vacuum

    That's a good idea. I still have the engine out and can take close up shots of each one. I do have a pic of all the lines once I removed them.

    The following post might help you a little more....Sadly, TuxStangs far right view of the "9G328 Idle Vacuum Valve (IVV)" has dropped off the net and isn't able to be retrived.


    Might help others ...

    Blue : 9E862 Air Cleaner Cold Weather Modulator (A/CL CWM) opens 55F closes 40F
    Green : 9E862 Air Cleaner Cold Weather Modulator (A/CL CWM) opens 76F closes 50F
