CYLINDER COMPRESSION PRESSURE LEAKAGE

Note. To perform a compression test on a MULTI-AIR equipped engine, the ignition MUST remain in the "key on" position. If the ignition is in the "off" position, the intake valves will not actuate and the result will be no compression.

Note. The results of a cylinder compression pressure test can be utilized to diagnose several engine malfunctions.

Note. Be certain the battery is completely charged and the engine starter motor is in good operating condition. Otherwise the indicated compression pressures may not be valid for diagnosis purposes.

  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 DELIVERY, GAS , STANDARD PROCEDURE»(ref-646230-S42658421212014072800000) .
  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. 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.
  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. 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.
  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»(ref-646216-S33438942572014072800000) .

CYLINDER COMBUSTION PRESSURE LEAKAGE

The combustion pressure leakage test provides an accurate means for determining engine condition.

Combustion pressure leakage testing will detect

  1. Exhaust and intake valve leaks (improper seating).
  2. Leaks between adjacent cylinders or into water jacket.
  3. 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 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.

CYLINDER COMBUSTION PRESSURE LEAKAGE DIAGNOSIS CHART

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. If equipped with an engine driven vacuum pump, high oil consumption can be caused by unchecked airflow into the pump. This can be caused by anything that opens the vacuum pump intake port up to the atmosphere such as a faulty vacuum pump, hose fitting, hose and brake booster. If there is not a restriction (normally caused by the pump pulling vacuum on the brake booster), then the vacuum pump will pump a high volume of air. This high volume of air will pressurize the crankcase and cause excessive oil burning and oil flow through the PCV system.
  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 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.
  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.

REPAIR DAMAGED OR WORN THREADS

CAUTIONBe sure that the tapped holes maintain the original center line.

Damaged or worn threads can be repaired. Essentially, this repair consists of

  1. Drilling out worn or damaged threads.
  2. Tapping the hole with a special Heli-Coil Tap, or equivalent.
  3. Installing an insert into the tapped hole to bring the hole back to its original thread size.

FORM-IN-PLACE GASKETS AND SEALERS

Note. All of the sealants mentioned below are not used on every engine, they are listed as a general reference guide. See appropriate Service Information for specific sealer usage.

There are numerous places where form-in-place gaskets are used on the engine. Care must be taken when applying form-in-place gaskets to assure obtaining the desired results. Do not use form-in-place gasket material unless specified. Bead size, continuity, and location are of great importance. Too thin a bead can result in leakage while too much can result in spill-over which can break off and obstruct fluid feed lines. A continuous bead of the proper width is essential to obtain a leak-free gasket. All sealing surfaces that use form-in-place gaskets and sealers must be free of grease or oil. Surfaces should be cleaned with Mopar® brake parts cleaner prior to sealer application. After the sealer is applied, the parts should be assembled within 10 minutes.

There are numerous types of form-in-place gasket materials that are used in the engine area. Mopar® Engine RTV GEN II, Mopar® ATF-RTV, and Mopar® Gasket Maker gasket materials, each have different properties and can not be used in place of the other.

MOPAR® ENGINE RTV GEN II is used to seal components exposed to engine oil. This material is a specially designed black silicone rubber RTV that retains adhesion and sealing properties when exposed to engine oil. Moisture in the air causes the material to cure. This material is available in three ounce tubes and has a shelf life of one year. After one year this material will not properly cure. Always inspect the package for the expiration date before use.

MOPAR® ATF RTV is a specifically designed black silicone rubber RTV that retains adhesion and sealing properties to seal components exposed to automatic transmission fluid, engine coolants, and moisture. This material is available in three ounce tubes and has a shelf life of one year. After one year this material will not properly cure. Always inspect the package for the expiration date before use.

MOPAR® GASKET MAKER is an anaerobic type gasket material. The material cures in the absence of air when squeezed between two metallic surfaces. It will not cure if left in the uncovered tube. The anaerobic material is for use between two machined surfaces. Do not use on flexible metal flanges.

MOPAR® BED PLATE SEALANT is a unique (green-in-color) anaerobic type gasket material that is specially made to seal the area between the bed plate and cylinder block without disturbing the bearing clearance or alignment of these components. The material cures slowly in the absence of air when torqued between two metallic surfaces, and will rapidly cure when heat is applied.

MOPAR® THREEBOND ENGINE RTV SEALANT is a unique gasket material that is specially made to retain adhesion and sealing properties when used to seal components exposed to engine oil.

CYLINDER HEAD GASKET

A cylinder head gasket leak can be located between adjacent cylinders or between a cylinder and the adjacent water jacket.

Possible indications of the cylinder head gasket leaking between adjacent cylinders are

  1. Loss of engine power
  2. Engine misfiring
  3. Poor fuel economy

Possible indications of the cylinder head gasket leaking between a cylinder and an adjacent water jacket are

  1. Engine overheating
  2. Loss of coolant
  3. Excessive steam (white smoke) emitting from exhaust
  4. Coolant foaming

HYDRAULIC LASH ADJUSTER

A tappet-like noise may be produced from several items. Check the following items.

  1. Engine oil level too high or too low. This may cause aerated oil to enter the adjusters and cause them to be spongy.
  2. Insufficient running time after rebuilding the cylinder head. Low speed running up to one hour may be required.
  3. Turn engine off and let set for a few minutes before restarting. Repeat this several times after engine has reached normal operating temperature.
  4. Low oil pressure.
  5. The oil screen in cylinder head or the oil passage to the cylinder head is plugged with debris.
  6. Air ingested into oil due to broken or cracked oil pump pick-up.
  7. Worn valve guides.
  8. Rocker arm ears contacting valve spring retainer.
  9. Rocker arm loose, adjuster stuck or at maximum extension and still leaves lash in the system.
  10. Oil leak or excessive cam bore wear in the cylinder head.
  11. Faulty lash adjuster.
  1. Check lash adjusters for "sponginess" while installed in the cylinder head and cam lobe at base circle. Depress part of rocker arm over the adjuster. Normal adjusters should feel firm when pressed quickly. When pressed very slowly, lash adjusters should collapse.
  2. Remove suspected lash adjusters, and replace.
  3. Before installation, make sure adjusters are full of oil. This can be verified by little plunger travel when lash adjuster is depressed quickly.

Scheme 550

Scheme 550: DESCRIPTION

The timing drive system consists of the following

  1. Timing Chain (2)
  2. Camshaft Sprockets (1, 3)
  3. Crankshaft Sprocket
  4. Right Timing Chain Guide (Moveable) (6)
  5. Left Timing Chain Guide (Fixed) (4)
  6. Timing Chain Tensioner (5)

The camshaft sprockets are attached to the cam phasers which are attached to the front of the camshafts and are used with the timing chain and crankshaft sprocket to turn the camshafts. The camshaft position sensors target is part of the camshafts and is used with the camshaft position sensors to provide the PCM with valvetrain position information.

The timing chain tensioner is installed in the right side of the engine block. Using engine oil pressure, the tensioner applies constant pressure to the right side (movable) timing chain guide, which in turn applies pressure to the timing chain. Also as the tensioner extends, it rachet locks in position to provide constant timing chain tension.

STANDARD PROCEDURE - VALVE TIMING VERIFICATION

CAUTIONPainted or colored chain links are used during initial engine assembly and can not be relied upon for valve timing verification. Only use top-dead-center marks, cylinder head cover mounting surface and camshaft sprocket marks to verify valve timing or engine damage may result.

Correct timing is critical for the NON free-wheeling designed, 2.0L engine. Engine timing can be verified by using the following procedures

  1. Remove the cylinder head cover. Refer to «COVER(S), CYLINDER HEAD, REMOVAL»(ref-646216-S10550530762014072800000) .
  2. Remove the spark plugs. Refer to «SPARK PLUG, REMOVAL»(ref-646264-S20945443012014072800000) . CAUTION: When aligning timing marks, always rotate engine by turning the crankshaft. Failure to do so will result in valve and/or piston damage.
