1. Clean the spark plug recesses with compressed air.
2. Remove the spark plugs and record the cylinder number of each spark plug for future reference.
3. Inspect the spark plug electrodes for abnormal firing indicators such as fouled, hot, oily, etc.
4. Disable the fuel system and perform the fuel system pressure release procedure. Refer to FUEL
SYSTEM PRESSURE RELEASE PROCEDURE .
5. Insert a compression pressure gauge and rotate the engine with the engine starter motor for three
revolutions.
6. Record the compression pressure on the 3rd revolution. Continue the test for the remaining cylinders.
7. Compression should not be less than 689 kPa (100 psi) and not vary more than 25 percent from cylinder
to cylinder.
8. If one or more cylinders have abnormally low compression pressures, repeat the compression test.
9. If one or more cylinders continue to have abnormally low compression pressures, perform the cylinder
combustion pressure leakage test. Refer to CYLINDER COMBUSTION PRESSURE LEAKAGE .
CYLINDER COMBUSTION PRESSURE LEAKAGE
The combustion pressure leakage test provides an accurate means for determining engine condition.
Combustion pressure leakage testing will detect:
Exhaust and intake valve leaks (improper seating).
Leaks between adjacent cylinders or into water jacket.
Any causes for combustion/compression pressure loss.
1. Check the coolant level and fill as required. DO NOT install the radiator cap.
2. Start and operate the engine until it attains normal operating temperature, then turn the engine OFF.
3. Remove the spark plugs.
4. Remove the oil filler cap.
5. Remove the air cleaner hose.
6. Calibrate the tester according to the manufacturer's instructions. The shop air source for testing should
not be valid for diagnosis purposes.
NOTE: The recommended compression pressures are to be used only as a guide
to diagnosing engine problems. An engine should not be disassembled to
determine the cause of low compression unless some malfunction is
present.
NOTE: If the same cylinder or cylinders repeat an abnormally low reading on the
second compression test, it could indicate the existence of a problem in
the cylinder in question.
2012 Dodge Journey R/T
2012 ENGINE 3.6L - Service Information - Journey
maintain 483 kPa (70 psi) minimum, 1, 379 kPa (200 psi) maximum and 552 kPa (80 psi) recommended.
7. Perform the test procedures on each cylinder according to the tester manufacturer's instructions. Set
piston of cylinder to be tested at TDC compression. While testing, listen for pressurized air escaping
through the throttle body, tailpipe and oil filler cap opening. Check for bubbles in the radiator coolant.
All gauge pressure indications should be equal, with no more than 25% leakage.
FOR EXAMPLE: At 552 kPa (80 psi) input pressure, a minimum of 414 kPa (60 psi) should be maintained in
the cylinder.

NOTE: Engine oil consumption may be greater than normal during engine break-in.
Repairs should be delayed until vehicle has been driven at least 7, 500 miles.
2012 Dodge Journey R/T
2012 ENGINE 3.6L - Service Information - Journey
Sustained high speed driving and high engine RPM operation may result in increased oil consumption.
Failure to comply with the recommended oil type and viscosity rating, as outlined in the owner's manual,
may impact oil economy as well as fuel economy.
Oil consumption may increase with vehicle age and mileage due to normal engine wear.
Oil leakage is not the same as oil consumption and all external leakage must be eliminated before
any action can be taken to verify and/or correct oil consumption complaints.
Verify that the engine has the correct oil level dipstick and dipstick tube installed.
Verify that the engine is not being run in an overfilled condition. Check the oil level 15 minutes
after a hot shutdown with the vehicle parked on a level surface. In no case should the level be above
MAX or the FULL mark on the dipstick.
OIL CONSUMPTION TEST
1. Check the oil level at least 15 minutes after a hot shutdown.
2. If the oil level is low, top off with the proper viscosity and API service level engine oil. Add one bottle of
MOPAR® 4-In-1 Leak Detection Dye into the engine oil.
3. Tamper proof the oil pan drain plug, oil filter, dipstick and oil fill cap.
4. Record the vehicle mileage.
5. Instruct the customer to drive the vehicle as usual.
6. Ask the customer to return to the servicing dealer after accumulating 500 miles, Check the oil level at
least 15 minutes after a hot shutdown. If the oil level is half way between the "FULL" and "ADD" mark
continue with the next step.
7. Using a black light, re-check for any external engine oil leaks, repair as necessary, if no external engine
oil leaks are present, continue with oil consumption diagnosis.
OIL CONSUMPTION DIAGNOSIS
1. Check the positive crankcase ventilation (PCV) system. Make sure the system is not restricted and the
PCV valve has the correct part number and correct vacuum source (18-20 in. Hg at idle below 3000 ft.
above sea level is considered normal).
2. Perform a CYLINDER COMPRESSION PRESSURE LEAKAGE test and CYLINDER - TO -
CYLINDER LEAKAGE TEST using the standard leak down gauge following manufacturers suggested
best practices.
NOTE: Because a few drops of external oil leakage per mile can quickly account for the
loss of one quart of oil in a few hundred miles, ensure no external engine oil
leaks are present.
NOTE: Verify the spark plugs are not oil saturated. If the spark plugs are oil
saturated and compression is good it can be assumed the valve seals or
valve guides are at fault.
2012 Dodge Journey R/T
2012 ENGINE 3.6L - Service Information - Journey
3. If one or more cylinders have more than 15% leak down further engine tear down and inspection will be
required.
TOP 19 REASONS THAT MAY LEAD TO ENGINE OIL CONSUMPTION
1. Tapered and Out-of-Round Cylinders
The increased piston clearances permit the pistons to rock in the worn cylinders. While tilted
momentarily, an abnormally large volume of oil is permitted to enter on one side of the piston. The rings,
also tilted in the cylinder, permit oil to enter on one side. Upon reversal of the piston on each stroke, some
of this oil is passed into the combustion chamber.
2. Distorted Cylinders
This may be caused by unequal heat distribution or unequal tightening of cylinder head bolts. This
condition presents a surface which the rings may not be able to follow completely. In this case, there may
be areas where the rings will not remove all of the excess oil. When combustion takes place, this oil will
be burned and cause high oil consumption.
3. Improper operation of "PCV "system
The main purpose of the Positive Crankcase Ventilation (PCV) valve is to recirculate blow-by gases back
from the crankcase area through the engine to consume unburned hydrocarbons. The PCV system usually
has a one way check valve and a make up air source. The system uses rubber hoses that route crankcase
blow by gases to the intake manifold. Vacuum within the engine intake manifold pulls the blow by gases
out of the crankcase into the combustion chamber along with the regular intake air and fuel mixture.
The PCV system can become clogged with sludge and varnish deposits and trap blow by gases in the
crankcase. This degrades the oil, promoting additional formation of deposit material. If left uncorrected,
the result is plugged oil rings, oil consumption, rapid ring wear due to sludge buildup, ruptured gaskets
and seals due to crankcase pressurization.
4. Worn Piston Ring Grooves
For piston rings to form a good seal, the sides of the ring grooves must be true and flat - not flared or
shouldered. Piston rings in tapered or irregular grooves will not seal properly and, consequently, oil will
pass around behind the rings into the combustion chamber.
5. Worn, Broken or Stuck Piston Rings
When piston rings are broken, worn or stuck to such an extent that the correct tension and clearances are
not maintained, this will allow oil to be drawn into the combustion chamber on the intake stroke and hot
gases of combustion to be blown down the cylinder past the piston on the power stroke. All of these
conditions will result in burning and carbon build up of the oil on the cylinders, pistons and rings.
6. Cracked or Broken Ring Lands
2012 Dodge Journey R/T
2012 ENGINE 3.6L - Service Information - Journey
Cracked or broken ring lands prevent the rings from seating completely on their sides and cause oil
pumping. This condition will lead to serious damage to the cylinders as well as complete destruction of
the pistons and rings. Cracked or broken ring lands cannot be corrected by any means other than piston
replacement.
7. Worn Valve Stems and Guides
When wear has taken place on valve stems and valve guides, the vacuum in the intake manifold will draw
oil and oil vapor between the intake valve stems and guides into the intake manifold and then into the
cylinder where it will be burned.
8. Bent or Misaligned Connecting Rods
Bent or misaligned connecting rods will not allow the pistons to ride straight in the cylinders. This will
prevent the pistons and rings from forming a proper seal with the cylinder walls and promote oil
consumption. In addition, it is possible that a bearing in a bent connect rod will not have uniform
clearance on the connecting rod wrist pin. Under these conditions, the bearing will wear rapidly and
throw off an excessive amount of oil into the cylinder.
9. Fuel Dilution
If raw fuel is allowed to enter the lubrication system, the oil will become thinner and more volatile and
will result in higher oil consumption. The following conditions will lead to higher oil consumption;
Excess fuel can enter and mix with the oil via a leaking fuel injector
Gasoline contaminated with diesel fuel
Restricted air intake
Excessive idling
10. Contaminated Cooling Systems
Corrosion, rust, scale, sediment or other formations in the water jacket and radiator will prevent a cooling
system from extracting heat efficiently. This is likely to cause cylinder distortion thus leading to higher
oil consumption.
11. Oil Viscosity
The use of oil with a viscosity that is too light may result in high oil consumption. Refer to the vehicle
owner's manual for the proper oil viscosity to be used under specific driving conditions and/or ambient
temperatures.
12. Dirty Engine Oil
Failure to change the oil and filter at proper intervals may cause the oil to be so dirty that it will promote
accumulation of sludge and varnish and restrict oil passages in the piston rings and pistons. This will
increase oil consumption; dirty oil by nature is also consumed at a higher rate than clean oil.
2012 Dodge Journey R/T
2012 ENGINE 3.6L - Service Information - Journey
13. Crankcase Overfull
Due to an error in inserting the oil dip stick so that it does not come to a seat on its shoulder, a low
reading may be obtained. Additional oil may be added to make the reading appear normal with the stick
in this incorrect position which will actually make the oil level too high. If the oil level is so high that the
lower ends of the connecting rods touch the oil in the oil pan excessive quantities of oil will be thrown on
the cylinder walls and some of it will work its way up into the combustion chamber.
14. Excessively High Oil Pressure
A faulty oil pressure relief valve may cause the oil pressure to be too high. The result will be that the
engine will be flooded with an abnormally large amount of oil in a manner similar to that which occurs
with worn bearings. This condition may also cause the oil filter to burst.
15. Aftermarket Performance Chips and Modification
Increasing performance through the use of performance/power enhancement products to a stock or factory
engine will increase the chance of excessive oil consumption.
16. Lugging Engine
Lugging is running the engine at a lower RPM in a condition where a higher RPM (more power/torque)
should be implemented. Especially susceptible on vehicles equipped with a manual transmission. This
driving habit causes more stress loading on the piston and can lead to increases in engine oil
consumption.
17. Turbocharged Engines
There is a possibility for PCV "push-over" due to higher crankcase pressure (as compared to naturally
aspirated engines) which is normal for turbocharged engines. This condition causes varying amounts of
engine oil to enter the intake manifold, charge air cooler and associated plumbing to and from the charge
air cooler, also a leaking turbocharger seal will draw oil into the combustion chamber where it will burn
(blue smoke from tail pipe may be present) and form carbon deposits which contribute to further oil
consumption as they interfere with proper engine function.
18. Restricted Air Intake
Excessive restriction in the air intake system will increase engine vacuum and can increase oil
consumption, an extremely dirty air filter would be one example of this situation.
19. Intake Manifold port seals
Engines that have a "V" configuration and a "wet valley" (3.3/3.8L) could draw oil into the intake ports
due to improper sealing between the intake manifold ports and cylinder head. Causes may include
improper torque of intake manifold bolts, corrosion (aluminum intake manifold) and or warped sealing
surface.
