2006 DODGE RAM SRT-10 check oil

3. Clean spark plug recesses with compressed air.
4. Remove the spark plugs.
5. Remove the oil fill cap.
6. Remove the air cleaner.
7. 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, with 552 kPa (80 psi) recommended.
8. Perform the test procedures on each cylinder according to the tester manufacturer’s instructions. While testing,
listen for pressurized air escaping through the throttle body, tailpipe and oil filler cap opening. Check for bubbles
in the coolant pressure bottle.
All gauge pressure indications should be equal, with no more than 25 percent leakage per cylinder.
FOR EXAMPLE:At 552 kPa (80 psi) input pressure, a minimum of 414 kPa (60 psi) should be maintained in the
cylinder.
CYLINDER HEAD GASKET FAILURE DIAGNOSIS
A cylinder head gasket leak can be located between adjacent cylinders, between a cylinder and the adjacent water
jacket, or an external coolant leak may be present.
Possible indications of the cylinder head gasket leaking between adjacent cylinders are:
Loss of engine power
Engine misfiring
Poor fuel economy
Possible indications of the cylinder head gasket leaking between a cylinder and an adjacent water jacket are:
Engine overheating
Loss of coolant
Excessive steam (white smoke) emitting from exhaust
Coolant foaming
CYLINDER-TO-CYLINDER LEAKAGE TEST
To determine if an engine cylinder head gasket is leaking between adjacentcylinders, follow the procedures in Cyl-
inder Compression Pressure Test in this section. An engine cylinder head gasket leaking between adjacent cylinders
will result in approximately a 50-70% reduction in compression pressure.Cylinders adjacent to each other will both
have low compression.
CYLINDER-TO-WATER JACKET LEAKAGE TEST
WARNING: Use extreme caution when the engine is operating with coolant pressure cap removed.
VISUAL TEST METHOD
With the engine cool, remove the coolant pressure cap. Start the engine andallow it to warm up until thermostat
opens.
If a large combustion/compression pressure leak exists, bubbles will be visible in the coolant.
COOLING SYSTEM TESTER METHOD
WARNING: With cooling system tester in place, pressure will build up fast.Excessive pressure built up, by
continuous engine operation, must be released to a safe pressure point. Never permit pressure to exceed
138 kpa (20 psi).
Install Cooling System Tester 7700 or equivalent to pressure cap neck. Start the engine and observe the tester’s
pressure gauge. If gauge pulsates with every power stroke of a cylinder a combustion pressure leak is evident.

CHEMICAL TEST METHOD
Combustion leaks into the cooling system can also be checked by using Bloc-Chek Kit C-3685-A or equivalent.
Perform test following the procedures supplied with the tool kit.
HYDRAULIC TAPPET NOISE DIAGNOSIS
PRELIMINARY STEP TO CHECKING THE HYDRAULIC TAPPETS
Before disassembling any part of the engine to correct tappet noise, checkengine oil level and oil pressure.
1. Check the engine oil level.
Oil Level Check: stop engine after reaching normal operating temperature
The oil level should never be above the FULL mark on dipstick, or below the ADD mark. Either of
these two conditions could be responsible for noisy tappets. Allow 5 minutes to stabilize oil level,
check dipstick.
2. Remove oil pressure sensor.
3. Install a reliable oil pressure gauge at oil pressure sensor location.
The oil pressure should be 206.8 - 551.6 kPa (30 - 80 psi) at 2000 rpm.
OIL LEVEL TOO HIGH
If oil level is above the FULL mark on dipstick, it is possible for the connecting rods to dip into the oil while engine
is running and create foam. Foam in oil pan would be fed to the hydraulic tappets by the oil pump causing them to
become soft and allow valves to seat noisily.
OIL LEVEL TOO LOW
Low oil level may allow pump to take in air which when fed to the tappets, causes them to become soft and allows
valves to seat noisily. Any leaks on intake side of pump through which air canbedrawnwillcreatethesametappet
action. Check the lubrication system from the intake strainer to the pump cover, including the relief valve retainer
cap. When tappet noise is due to aeration, it may be intermittent or constant, and usually more than one tappet will
be noisy. When oil level and leaks have been corrected, engine should be operated at fast idle to allow all of the air
inside of the tappets to be bled out.
VALVE TRAIN NOISE DIAGNOSIS
To determine source of valve train noise, operate engine at idle with cylinder head covers removed and listen for
source of the noise.
NOTE: Worn valve guides or cocked springs are sometimes mistaken for noisytappets. If such is the case,
noise may be dampened by applying side thrust on the valve spring. If noise is not appreciably reduced, it
can be assumed the noise is in the tappet. Inspect the rocker arm push rod sockets and push rod ends for
wear.
Valve tappet noise ranges from light noise to a heavy click. A light noise isusually caused by excessive leak-down
around the unit plunger which will necessitate replacing the tappet, or bythe plunger partially sticking in the tappet
body cylinder. A heavy click is caused either by a tappet check valve not seating, or by foreign particles becoming
wedged between the plunger and the tappet body causing the plunger to stickin the down position. This heavy click
will be accompanied by excessive clearance between the valve stem and rocker arm as valve closes. In either case,
tappet assembly should be removed and replaced.
ENGINE OIL LEAK INSPECTION
Begin with a thorough visual inspection of the engine, particularly at thearea of the suspected leak. If an oil leak
source is not readily identifiable, thefollowingstepsshouldbefollowed:
1. Do not clean or degrease the engine at this time because some solvents maycause rubber to swell, temporarily
stopping the leak.
2. Add an oil soluble dye (use as recommended by manufacturer). Start the engine and let idle for approximately 15
minutes. Check the oil dipstick to make sure the dye is thoroughly mixed as indicated with a bright yellow color
under a black light.

3. Using a black light, inspect the entire engine for fluorescent dye, particularly at the suspected area of oil leak. If
the oil leak is found and identified, repair as necessary.
4. If dye is not observed, drive the vehicle at various speeds for approximately 24 km (15 miles), and repeat inspec-
tion.
5.If the oil leak source is not positively identified at this time, proceed with the air leak detection test method
as follows:
1. Disconnect the PCV hoses at the cylinder head covers and plug or cap the outlet on the covers.
2. Attach an air hose with pressure gauge and regulator to the dipstick tube.
CAUTION: Do not subject the engine assembly to more than 20.6 kpa (3 PSI) of test pressure.
3. Gradually apply air pressure from 6.89 kPa (1 psi) to 17.23 kPa (2.5 psi) maximum while applying soapy water
at the suspected source. Adjust the regulator to the suitable test pressure that provides the best bubbles which
will pinpoint the leak source. If the oil leak is detected and identified, repair per service manual procedures.
4. If the leakage occurs at the crankshaft rear oil seal area, refer to the section, Inspection for Rear Seal Area
Leak.
6. If no leaks are detected, turn off the air supply. Remove the air hose, allplugs, and caps. Connect the PCV
hoses. Proceed to next step.
7. Clean the oil off the suspect oil leak area using a suitable solvent. Drive the vehicle at various speeds approx-
imately 24 km (15 miles). Inspect the engine for signs of an oil leak by usinga black light.
NOTE: If oil leakage is observed at the dipstick tube to oil pan location; remove the tube, clean and reseal
using Mopar
Stud & Bearing Mount (press fit tube applications only), and for O-ring style tubes, remove
tube and replace the O-ring seal.
INSPECTION FOR REAR SEAL AREA LEAKS
Since it is sometimes difficult to determine the source of an oil leak in therear seal area of the engine, a more
involved inspection is necessary. The following steps should be followedto help pinpoint the source of the leak.
If the leakage occurs at the crankshaft rear oil seal area:
1. Disconnect the battery.
2. Raise the vehicle.
3. Remove clutch housing inspection cover and inspect rear of block for evidence of oil. Use a black light to check
for the oil leak. If a leak is present in this area, remove transmission for further inspection.
a. Circular spray pattern generally indicates seal leakage or crankshaftdamage.
b. Where leakage tends to run straight down, possible causes are a porous block, oil gallery cup plug or rear
crankshaft seal retainer gasket leak. See proper repair procedures for these items.
4. If no leaks are detected, pressurize the crankcase as previously described.
CAUTION: Do not exceed 20.6 kPa (3 psi).
5. If the leak is not detected, very slowly turn the crankshaft and watch forleakage. If a leak is detected between
the crankshaft and seal while slowly turning the crankshaft, it is possible the crankshaft seal surface is damaged.
The seal area on the crankshaft could have minor nicks or scratches that canbe polished out with emery cloth.
CAUTION: Use extreme caution when crankshaft polishing is necessary to remove minor nicks and
scratches. The crankshaft seal flange is especially machined to complement the function of the rear oil seal.
6. For bubbles that remain steady with shaft rotation, no further inspection can be done until disassembled.
7. After the oil leak root cause and appropriate corrective action have been identified, replace component(s) as
necessary.

5. Identify the fluid in the cylinder(s) (i.e., coolant, fuel, oil or other).
6. Make sure all fluid has been removed from the cylinders. Inspect engine for damage (i.e., connecting rods, pis-
tons, valves, etc.)
7. Repair engine or components as necessary to prevent this problem from re-occurring.
CAUTION: Squirt approximately one teaspoon of oil into the cylinders, rotateenginetolubricatethecylin-
der walls to prevent damage on restart.
8. Install new spark plugs.
9. Drain engine oil and remove oil filter.
10. Fill engine with specified amount of approved oil and install new oil filter.
11. Connect negative battery cable.
12. Start engine and check for any leaks.

LUBRICATION
DESCRIPTION
The engine lubrication system is a full-flow filtration pressure feed type.
OPERATION
Engine oil stored in the oil pan is taken in and discharged by an internal geartypeoilpump,whichisdrivenbythe
crankshaft. A pressure relief valve is located in the timing chain case cover; it regulates oil pressure. The oil is
pumped through an oil filter and feeds a main oil gallery. Also, oil is routedtoanexternaloilcooler.Themainoil
gallery feeds oil under pressure to the main bearings, connecting rod bearings, and camshaft bearings. Passages in
the cylinder block feed oil to the hydraulic lifters. The oil then flows through hollow pushrods, which feed the rocker
arm pivots.
DIAGNOSIS AND TESTING
CHECKING ENGINE OIL PRESSURE
1. Remove oil pressure sensor (Refer to 9 - ENGINE/LUBRICATION/OIL PRESSURE SENSOR - REMOVAL).
2. Install oil pressure gauge.
3. Warm engine at high idle until thermostat opens.
CAUTION: If oil pressure is 0 at idle, Do Not Run engine at 3000 RPM.
4. Oil pressure should be 68.9 kPa (10 psi) at idle or 310 - 517 kPa (45 - 75 psi)at 3000 RPM.
5. If oil pressure is 0 at idle, shut off engine. Check for a clogged oil pick-up screen or a pressure relief valve stuck
open.

3. Gradually apply air pressure from 6.89 - 17.23 kPa (1 - 2.5 psi) maximum while applying soapy water at the
suspected source. Adjust the regulator to the suitable test pressure thatprovide the best bubbles which will pin-
point the leak source. If the oil leak is detected and identified, repair per service manual procedures.
4. If the leakage occurs at the rear oil seal area, refer to the section, Inspection for Rear Seal Area Leak.
5. If no leaks are detected, turn off the air supply and remove the air hose and all plugs and caps. Install the PCV
valve.
6. Clean the oil off the suspect oil leak area using a suitable solvent. Drive the vehicle at various speeds approx-
imately 24 km (15 miles). Inspect the engine for signs of an oil leak by usinga black light.
