Jeep Six-Cylinder Setup Guide
Thank you for purchasing a Golen performance engine. Your engine will give you many years of
fun and reliability provided you properly follow these instructions for setup and break-in. The
initial setup and break-in of your engine is the most critical part of its life and will determine how it
runs for years to come. Please remember, just because an engine is built with top-end
performance components doesn’t mean it will run correctly with improper break-in and tuning.
We highly recommend that you read through all of this information before starting your
installation, that way you know what to expect throughout the process and may call the tech line
and ask any questions before beginning the installation.
Unpacking and Inspection
Uncrate your engine and visually inspect it for any damage that may have occurred during
shipping. If damage is visible, contact the freight carrier and GES immediately.
Compare the GES engine to the engine you removed from your car. Make sure all mounting
holes and other features are identical between the two.
Remove, clean and thoroughly inspect the following parts from your original motor: oil pan, motor
mounts, starter, flywheel, timing chain cover, fuel pump, water pump, intake manifold, injection,
distributor and ignition components, thermostat, exhaust manifolds, harmonic dampener, oil and
water temperature sending units, dipstick and rocker covers. This is a good time to replace any
part that may have excessive wear. After inspection, install the parts on your GES high
performance engine. We recommend installing the distributor and injection after the engine is
bolted in to prevent damage to these components.
Installation
Install the engine into the engine compartment and bolt up all mounts. Inspect the following parts
and their respective mounting hardware: air conditioning, alternator, power steering pump, smog
pump, radiator, pulleys, fan, fan shroud, hoses, belts, etc. These parts can also have excessive
wear and can be more easily replaced at this time.
Install the fuel injection and throttle cable, then fill the radiator with the proper amount of coolant
and check for leaks.
Install a new oil filter and pour the required amount of oil (6 qrts) into the engine. It is mandatory to run a
true break in oil such as Joe Gibbs BR or Royal Purple Break In, failure to do so can result and
premature camshaft wear. You can run the break in oil for 500 miles as long as it stays clean, after that
you can run either a Zinc based oil such as the Joe Gibb’s Hot Rod oil or you can use a conventional or

synthetic 10/40 or 15/40 oil but you will need to add a Zinc Additive to every oil change with these for the
entire life of the engine.
Priming the Oil Pump
At this point you need to prime your engines oil pump. This step is very important and can severely
damage your engine and void your warranty if not performed properly. Please carefully follow the
instructions included in this packet labeled “How to Prime the Jeep Oil Pump” then return to this
page once this is complete.
Installing the Distributor/Cam Sensor
Now you should install the distributor. Follow the instructions included in this packet labeled
“Installing the Jeep Distributor/Cam Sensor” then return to this page.
Starting the Engine
At this point, you are just about ready to start your engine. Reconnect the positive and negative
battery cables and double-check all connections. Once this is complete, call the Golen Engine
tech line at 800-591-9171 ext 2. This is a required part of our standard setup procedure and allows us
to review all of the final details before starting your engine.
Now you are ready to start your new engine. Keep in mind that you must break in the camshaft.
This is just as important as priming the oil as you may also severely damage your engine and
void the warranty by not performing this step. Please follow the instructions in “Jeep Camshaft
Break-In Procedure” then return to this page.
After the cam break-in has been completed, check for leaks. Be sure to check under the vehicle.
Also check the spark plugs. The porcelain should be fairly clean, almost white. Brand new spark
plugs will remain fairly clean after the cam break-in and should not be interpreted as a sign of a
lean condition. If the spark plugs look black or do not look fairly clean after the cam break-in,
please call the Golen Engine tech line at 800-591-9171 ext 2.
Driving the Vehicle
Now it’s time to go for a drive. Run the engine in high gear and lug it checking for detonation
(spark knock or ping). If you experience spark knock call Golen Engine to discuss.
Next make a test run on the road reaching 30mph. Keep this first ride limited to 2-3 miles, then
return and check the spark plugs. They should still be fairly clean, but may start showing a light
brown color that will get slightly darker as you put more miles on the engine. This is a good sign
and means your engine is running properly. If the spark plugs look black please call the Golen
Engine tech line at 800-591-9171 ext 2.
Periodically accelerate to 50mph and decelerate rapidly. Repeat this procedure at least 10 times.
Applying loads to the engine for short periods of time causes increased ring pressure against the
cylinder walls and helps seat the rings. The rapid deceleration increases vacuum and gives extra
lubrication to the piston and ring assemblies. Drive normally but not at continuous high speeds or
under heavy loads for the first 500 miles. It is important to not “lug” or “baby” the engine during
break-in because the rings will not seat properly.
Double check all bolt torques, hose connections, coolant and oil levels. We
recommend that you check these items for the first two weeks of run time. It will take about 500 miles
to break the engine in all the way. It is mandatory to run a Zinc based oil such as the Joe Gibb’s Hot
Rod oil or a Zinc Additive with every oil change for the entire life of the engine.

How to Prime the Jeep Oil Pump
Priming the oil pump in your Jeep engine brings the oil pressureup to normal before the engine is started.
This will protect the engine from premature failure cause by a dry start. Dry start is a condition whereby
the engine is initially run for a short time without any lubrication on the bearings. This can wipe and spin
bearings and cause quick and devastating damage to the engine internals. Priming the engine using the
following instructions ensures that the first time it is started there is proper lubrication on all internal parts.
Once the engine has been primed and run for the first time, a thin layer of oil always remains on all of the
bearings and protects them for those first few critical seconds during startup while the pressure builds up.
Priming the oil pump is the most important step to take just before starting your engine for the
first time!!
1. After you install the engine into the Jeep’s engine compartment, make sure that you install a
new name-brand oil filter such as Wix and fill the engine with the proper amount of oil. Using the factory
oil pan and oil dip-stick, fill to the factory level on the stick.
2. Install the priming tool into the engine through the distributor hole and attach a ”electric drill
to the priming tool. If you don’t have a priming tool, you may cut the handle off of a flat-head
screwdriver and use that to turn the oil pump drive shaft. Be careful, though, as the cut-off
end may be sharp.
3. Next, turn the drill clockwise until you feel the drill load-up. This may take a few minutes, but
you will eventually feel the drill start to torque back on your arm. This is a sign that the oil has
now been pulled through the oil pump pick-up tube and is now actually pumping through the
engine.
4. Continue running the drill for another minute after the drill loads-up. This ensures that all of
the bearings and moving components have been properly lubricated.
5. After priming is completed, install the distributor and start the engine.
6. If you have any questions regarding priming the oil pump, please call the GES tech line at 1-
800-591-9171 Ext 2.

Installing the Jeep Distributor/Cam Sensor
1. Ensure the #1 piston is at Top Dead Center on the compression stroke. To find TDC on the
compression stroke you can remove the #1 spark plug and put your finger over the spark plug hole while
you have someone turn the engine over slowly by hand, once you feel pressure building up on your finger
bring the piston to TDC and you’ve got it.
2. Remove the distributor cap and rotor and look at the pulse ring on the distributor (see picture below),
note that there are two holes one for the 2.5 (4) cylinder engine and one for the 4.0 (6) cylinder engine.
(pulse ring is located under the rotor and my require you to remove the plastic dust cover to expose it)
3. Insert a 3/16”pin (an allen wrench will do) into the small hole under the bottom side of the distributor
base. Then find the 4.0 (6) cylinder hole in the pulse ring which is located at the end of the half moon
pulse ring and line the two up and lock out the pulse ring. Note: The hole that is “free”is
to time the four cylinder engine, do not use for the six cylinder engine.
4. Pre-position the oil pump slot at 11 o’clock to accept the distributor drive as shown in the picture below.
5. Insert the distributor, engaging the oil pump. Note: The rotor will not be aligned to the
# 1 plug wire on the cap. Once the distributor is fully engaged and flush with the block remove the
alignment pin.
6. Install and tighten the securing bolt at the base of the distributor. Do not rotate the distributor base at all
for this will not change the ignition timing since this is actually a cam sensor for the engine

Jeep Camshaft Break-In Procedure
Follow all of the steps in the “Startup Guidelines”before attempting to start your new Jeep
Engine and make sure that you are using a true Zinc Based break in oil such as the Joe Gibb’s BR or the
Royal Purple Break In oil, this is mandatory in order to break the camshaft in properly
Get the distributor set properly so the engine will fire off immediately by following the steps in
“Installing the Jeep Distributor/Cam Sensor”.
Start the engine and make sure you have oil pressure and a good idle for 15-20 seconds without
using any throttle. If it doesn’t idle well, you need to shut the engine down and determine the
cause of the problem before performing the cam break-in. If this occurs, call the Golen tech line
@ 800-591-9171 Ext 2, Monday through Friday, 9am to 5pm Eastern time.
Assuming oil pressure and idle are good, bring the engine up to 2000 rpm. You will keep the
engine at 2000 rpm for 20 minutes watching for oil or anti-freeze leaks, oil pressure, and engine
temperature. Also listen for general engine operation. The lifters may take up to 20 minutes to
complete pump-up and during this time may make some noise this is perfectly normal. You might also
notice the header getting red hot if this happens shut the engine down and let it cool. Once the engine
has had time to cool (about 30 min) the resume whatever time you have left on the 20 min break in.
After the cam break-in has been completed, you need change the oil filter only, leave the expensive break
in oil in the engine for the first 500 miles as long as it looks clean. After the filter has been changed, you
may then perform the final inspection steps in “Startup Guidelines”.
Note: You will need to use either a Zinc based oil such as the Joe Gibb’s Hot Rod oil or at least a
Zinc additive in every oil change for the life of the engine. Failure to follow this guideline will
result in premature camshaft wear for sure.

Why Zinc in my oil?
The Jeep inline 6 cylinder engine has what is called a flat tappet camshaft which requires certain oil
additives one of which is Zinc. The Zinc additive puts a protective coating on all metallic parts inside the
engine and the camshaft needs this more than any to guarantee a long life.
Now you might be asking yourself why now? All early model engines from the 80’s and earlier came from
the factory with a flat tappet camshaft. Well the US government noticed a few years ago that a huge
percentage of newer vehicles were failing their local emissions tests. Once they looked into it they found
that the Catalytic converters were failing due to the higher levels of Zinc that were present in the engine
oil at the time. As all engines even brand new engines run they burn small amounts of oil through the
combustion chamber and the Zinc was attacking the Cat’s and causing them to break down prematurely
causing the failed emissions tests.
So as you can imagine the US government forced the auto makers to change their recommendations on
oils and in turn had to force the oil producers to dramatically lower the levels of Zinc in the oils to solve
the problem which they did. Now at this time about 2007 the Jeep 4.0 engine was not in production any
longer and the Jeeps that were on the road had long since been properly broken in on the old high Zinc
oil that was available in 2006 and earlier.
Now comes all the engines that are being built in the performance aftermarket such as the Jeep 4.6
stroker engine which has a flat tappet camshaft. We have gone through a seminar with Joe Gibb’s Racing
Oils to get all of the information that you are reading in this article and have found by using their oil or at
least a Zinc additive on the break in as well as all of the oil changes to come has almost eliminated
premature camshaft wear on our Jeep 4.6 engines.
So in close it is 100% mandatory to break your new Golen Jeep 4.6 engine in with a Zinc based oil and to
run a Zinc based oil for the life of the engine.
