Need to know the proper routing of vacuum lines on 69 olds carburator


Standing in front of the car, the lower left vacuum port on the carb goes to the distributor. The upper left port goes to the vacuum switch for the secondaries. The brake booster screws into the rear base of the carburator. The transmission kickdown plugs into a nipple on the rear of the intake manifold.

67 ranchero will not run at idle speed


See you have a different vehicle than 1999 Escort. If you have a 1967 model, there are many things to look for. You did not say the engine and carburetor type and size which would help us solve this.

The power valve in front of some carbs is connected to the accelerator rod by the throttle lever. The rubber part inside can come apart. With older vehicle parts, you do not have the original Vacuum fittings or intake manifolds present all of the time. Some used a complicated "Vacuum tree" in the intake manifold. This can cause RPM problems when the wrong hose is routed to the wrong port. These "Vacuum Trees" work off of Water heat to route Vacuum.

The Automatic versions of some of these vehicles often had a Vacuum shift and if the diaphragm was leaking, RPM could be affected. There were also parts called "Dashpots" which could have Vacuum lines routed to the "Vacuum tree" which triggers throttle position.

Any Intake air leaks will speed up RPM. If my comments do not fix this, supply the engine size and carburetion and another Expert may be able to do more.

answer , very carefully ...

drain coolant , remove and mark all vacuum lines , make a schematic to diagram your hose routing, disconnect and plug all fuel lines, remove distributor and mark location of rotor, disconnect battery, remove any necessary cables, brackets and or accesseries, remove intake mounting bolts, note length of bolts and reference location, pry up on intake , remove intake, scrape old gasket off , must be very clean to reinstall new gasket or you will cause a leak..

I am installing a Holley 2818 on my '65 327 and need help with routing the PCV lines. Which line goes to the PCV inlet on the carb? The rear block inlet or the one on the oil filler neck?


On the 2818 holley there is a calibrated elbow on drivers side of carb about centre of the main body.This connects to oil filler stand pipe in front of intake.Fresh air hose goes from air cleaner to back of block where road draft tube used to be before PCV came along.
The calibrated elbow serves as PCV metered orifice.Be sure flame arrester screen is inside of air cleaner on fresh air connection.

  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Properly relieve the fuel system pressure.
  3. Drain the coolant system.
  4. Remove or disconnect the following:
    • Negative battery cable
    • Air cleaner fresh air hose
    • Positive Crankcase Ventilation (PCV) valve hose
    • Fuel line from the rail
    • Throttle cable from the throttle body
    • Throttle cable bracket nuts
    • Fuel injector electrical connectors
    • Throttle Position (TP) sensor electrical connectors
    • Idle Air Control (IAC) valve electrical connectors
    • Manifold Absolute Pressure (MAP) sensor electrical connectors
    • Exhaust Gas Recirculation (EGR) valve electrical connectors
    • Heater hose from the intake manifold outlet
  5. Position the wiring harness over the brake master cylinder
  6. Remove or disconnect the following:
    • Intake manifold support bracket bolt
    • Label the vacuum line for proper assembly
    • Drive belt
    • Power steering pump
    • Upper intake manifold bolts
    • Evaporative Emissions (EVAP) canister purge valve solenoid vacuum hose
    • Brake booster vacuum hose
    • Lower intake manifold bolts
    • Intake manifold
    To install:
  7. Thoroughly clean all gasket mating surfaces. Be careful not to damage or score the aluminum surface. If replaced, use Loctite® 290, to seal the new PCV valve inlet tube into the manifold. NOTE: Refer to Section 1 of this manual for the intake manifold torque sequence illustration. The illustration is located after the Torque Specification Chart.
  8. Install or connect the following:
    • New gasket and manifold. Torque the nuts in sequence to 22 ft. lbs. (30 Nm).
    • Power steering pump. Torque the fasteners to 27 ft. lbs. (38 Nm).
    • Drive belt.
    • Heater hose and install the manifold support bracket bolt. Tighten the bolt to 22 ft. lbs. (30 Nm).
    • Lubricate the male ends of the fuel lines with a few drops of clean engine oil, then connect the fuel supply and return lines.
    • Fuel line(s) in the retaining bracket. Torque the mounting screw to 36 inch lbs. (4 Nm).
    • Throttle cable to the throttle body and attach the accelerator cable bracket. Torque the bolts to 22 ft. lbs. (30 Nm).
    • Reposition the wiring harness and connect the wiring and vacuum hoses to their original locations. The harness leads to the TP sensor and EGR solenoid must be routed between the intake manifold runners.
    • Negative battery cable
  9. Fill the coolant system.
  10. Prime the fuel system by cycling the ignition ON for 5 seconds and OFF for 10 seconds a few times without cranking the engine.
  11. Start the engine, check for leaks, and repair if necessary.

Engine flooding on #2 and #4 cylinders, replaced fuel injectors, TPS, and ECM.


Just a suggestion, but get a fuel pressure gauge and check your pressure regulator.  They use intake vacuum to control a diaphram that regulates the fuel based on RPM/vacuum relationship.  I had a Supra with a similar problem - had all the mechanics stumped.  It was flooding in #1 and # 2 cyl. badly.  Turns out rubber diaphram in pressure reg. cracked and the engine vacuum was pulling gas directly into the intake manifold on top of what the injectors were supplying!  Also, lifting the regulator's vacuum line off the manifold and holding it close to the vacuum, you'll actually see gas getting sucked in if that's the problem.  I took the same route you did, replaced inj. etc, before I stumbled on this.  Good luck!
