General Operating Principals
The AMPCO Vapor Lubricator has been engineered on an exclusive principle to meter and introduce a
properly compounded lubricant, as a completely dispersed vapor mist, into the fuel/air stream, below
the point of carburetion and without dilution by the engine fuel, to result in even and immediate
distribution of the oil particles to all cylinders of an engine. The use of a good lubricant is essential to
satisfactory performance of the AMPCO Vapor Lubricator. The AMPCO method of Auxiliary Lubrication
will result in decreased engine wear, reduced engine deposits, improved valve and ring action, lowered
fuel and oil consumption, and increased power potential. Since no two engines are identical in
requirements or operate under the same conditions, the AMPCO Vapor Lubricator is equipped with an
adjustable oil flow control valve which affords proper adjustment and regulation of oil input to provide
for Finger Tip Control of performance and oil consumption.
To Adjust Lubricator
Care of Lubricator
- Assemble Mounting Bracket to Lubricator with screws and lock washers, Mounting Bracket may
be reversed if required. - Locate Lubricator and Mounting Bracket on fire wall or other convenient location. Keep oil
container from contact with wall. Drill or punch starting holes for metal holding screws. Mount
securely. - Connect copper tubing to Injector Plate or Nozzle. On dual-type installations, support dual
connector bow with a 3/8" wrench while attaching tubing. - Remove filter-type Filler Cap and fill oil container to top marking with a lubricant. Replace Filler
Cap. Tighten oil container. - We recommend the use of Marvel Mystery Oil for your upper cylinder lubricant.
To Attach to Engine
- An installation and service kit is required with each Lubricator. Specific installation information is
included with each kit. - Attachment of the Lubricator to the engine provides for either a specific Injector Plate or
Injector Nozzle. The Lubricator will not function properly without the correct attachment of
either the Injector Plate or Nozzle. - Injector Plates and Nozzles are illustrated below as required for various types of engines. These
Injector Plates and Nozzles have been engineered to provide for controlled vapor mist injection
of the lubricant into the fuel/air stream with proper proportions of lubricant and air. The air/fuel
ratio of an engine cannot be disturbed with the use of the proper Injector Plate or Nozzle and
the correct installation of this part. - To use the Injector Nozzle connection, a suitable opening must be available in the intake
manifold, in the riser section and either above or below the carburetor, depending on updraft or
downdraft type. If the manifold is to be drilled, use a 21/64" drill and tap for 1/8th pipe thread.
Use caution not to let any chips fall down inside the intake manifold pipe. Use a magnet next to
the drill and tap or grease the drill and tap to catch the metal chips. Do not attempt to drill
through a double wall or hot spot section of the intake manifold. Use reamed and flared
reducing bushing as required to avoid interference with vapor mist injections.
There is an alternative method to drilling and tapping the manifold. The PCV hose, or other
suitable vacuum hose directly entering the base of the carburetor or intake manifold, can be cut
and a "T" installed (see picture below.) A universal brass "T" has been manufactured especially
for this installation.

for Finger Tip Control of performance and oil consumption.
To Adjust Lubricator
- Start engine. Idle few minutes until warm.
- From finger-tight closed position, open Oil control Valve 1/2 to 3/4 turn to left and continue
engine idle. Continue for a few minutes. - Reduce oil flow and set Oil Control Valve at 1/4 turn from closed position. Observe oil flow
which should be steady but not heavy. - Accelerate engine 3 or 4 times and return to normal idle. Adjust idling speed and low speed
mixture on carburetor for smooth idle. A secondary adjustment of the Oil Control Valve and
carburetor controls may be made after initial 100 or more miles of operation to correct Oil
Control Valve adjustment to engine requirements and smooth idle.
Care of Lubricator
- This Lubricator is designed to provide thousands of miles of trouble-free operation. Air filtration
is provided at the Air Inlet and Filler Cap. If congestion through accumulated road and engine
dirt should restrict filter elements, remove and wash and replace. Replacement filter elements
are available. - The Oil Control Valve provides for a micrometer-type adjustment, and this mechanism should not
be removed or handled roughly. The Oil Control Valve should be opened to 1/2 to 3/4 turn for
a few minutes at 100 to 1500 mile intervals or when refilling the Lubricator to clear any foreign
material from valve and seat. Reset valve to normal position for maximum engine efficiency.
