C-823, equipped with 220 grit stones, is the best tool for this job. In addition to deglazing, it will reduce taper and out-of-round, as well as removing light scuffing, scoring and scratches. Usually, a few strokes will clean up a bore and maintain the required lim- its.
CAUTION: DO NOT use rigid type hones to remove cylinder wall glaze.
(2) Deglazing of the cylinder walls may be done if the cylinder bore is straight and round. Use a cylin- der surfacing hone, Honing Tool C-3501, equipped with 280 grit stones (C-3501-3810). about 20-60
strokes, depending on the bore condition, will be suf- ficient to provide a satisfactory surface. Using honing oil C-3501-3880, or a light honing oil, available from major oil distributors.CAUTION: DO NOT use engine or transmission oil, mineral spirits, or kerosene.
(3) Honing should be done by moving the hone up and down fast enough to get a crosshatch pattern. The hone marks should INTERSECT at 50° to 60° for proper seating of rings (Fig. 3).
(4) A controlled hone motor speed between 200 and 300 RPM is necessary to obtain the proper cross- hatch angle. The number of up and down strokes per minute can be regulated to get the desired 50° to 60° angle. Faster up and down strokes increase the cross- hatch angle.
(5) After honing, it is necessary that the block be cleaned to remove all traces of abrasive. Use a brush to wash parts with a solution of hot water and deter- gent. Dry parts thoroughly. Use a clean, white, lint- free cloth to check that the bore is clean. Oil the bores after cleaning to prevent rusting.
STANDARD PROCEDURE - FORM-IN-PLACE GASKETS AND SEALERS
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.
There are numerous types of form-in-place gasket materials that are used in the engine area. Mopart Engine RTV GEN II, Mopart ATF-RTV, and Mopart Gasket Maker gasket materials, each have different properties and can not be used in place of the other.
MOPARt ENGINE RTV GEN II Mopart Engine RTV GEN II is used to seal com- ponents exposed to engine oil. This material is a spe- cially 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.
MOPARt ATF RTV Mopart ATF RTV is a specifically designed black silicone rubber RTV that retains adhesion and seal- ing properties to seal components exposed to auto- matic 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.

MOPARt GASKET MAKER
DR ENGINE 8.0L (Continued)
Mopart 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.
MOPARt GASKET SEALANT Mopart Gasket Sealant is a slow drying, perma- nently soft sealer. This material is recommended for sealing threaded fittings and gaskets against leakage of oil and coolant. Can be used on threaded and machined parts under all temperatures. This mate- rial is used on engines with multi-layer steel (MLS) cylinder head gaskets. This material also will pre- vent corrosion. Mopart Gasket Sealant is available in a 13 oz. aerosol can or 4oz./16 oz. can w/applicator.
FORM-IN-PLACE GASKET AND SEALER APPLICATION
Assembling parts using a form-in-place gasket requires care but it’s easier than using precut gas- kets.
Mopart Gasket Maker material should be applied sparingly 1 mm (0.040 in.) diameter or less of sealant to one gasket surface. Be certain the material sur- rounds each mounting hole. Excess material can eas- ily be wiped off. Components should be torqued in place within 15 minutes. The use of a locating dowel is recommended during assembly to prevent smear- ing material off the location.
Mopart Engine RTV GEN II or ATF RTV gasket material should be applied in a continuous bead approximately 3 mm (0.120 in.) in diameter. All mounting holes must be circled. For corner sealing, a 3.17 or 6.35 mm (1/8 or 1/4 in.) drop is placed in the center of the gasket contact area. Uncured sealant may be removed with a shop towel. Components should be torqued in place while the sealant is still wet to the touch (within 10 minutes). The usage of a locating dowel is recommended during assembly to prevent smearing material off the location.
Mopart Gasket Sealant in an aerosol can should be applied using a thin, even coat sprayed completely over both surfaces to be joined, and both sides of a gasket. Then proceed with assembly. Material in a can w/applicator can be brushed on evenly over the sealing surfaces. Material in an aerosol can should be used on engines with multi-layer steel gaskets.

COOLING SYSTEM TESTER METHOD
WARNING: WITH COOLING SYSTEM TESTER IN PLACE, PRESSURE WILL BUILD UP FAST. EXCES- SIVE PRESSURE BUILT UP, BY CONTINUOUS ENGINE OPERATION, MUST BE RELEASED TO A SAFE PRESSURE POINT. NEVER PERMIT PRES- SURE 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.
REMOVAL
(1) Disconnect the negative cable from the battery. (2) Drain cooling system (Refer to 7 - COOLING -
STANDARD PROCEDURE).
(3) Remove the heat shields (Fig. 7).

†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 adjacent cylinders, follow the proce- dures in Cylinder Compression Pressure Test in this section. An engine cylinder head gasket leaking between adjacent cylinders will result in approxi- mately a 50–70% reduction in compression pressure.
CYLINDER-TO-WATER JACKET LEAKAGE TEST
WARNING: USE EXTREME CAUTION WHEN THE ENGINE IS OPERATING WITH COOLANT PRES- SURE CAP REMOVED.
VISUAL TEST METHOD
With the engine cool, remove the coolant pressure cap. Start the engine and allow it to warm up until thermostat opens.
If a large combustion/compression pressure leak
exists, bubbles will be visible in the coolant.

VALVE GUIDES
Measure valve stem guide clearance as follows: (1) Install Black Valve Guide Sleeve Tool C-6819
over valve stem for the INTAKE valve and install valve (Fig. 14). The special sleeve places the valve at the correct height for checking with a dial indicator. (2) Install Silver Valve Guide Sleeve Tool C-6818
over valve stem for the EXHAUST valve and install valve. The special sleeve places the valve at the cor- rect height for checking with a dial indicator.(3) Attach Dial Indicator Tool C-3339 to cylinder head and set it at right angle of valve stem being measured (Fig. 15).
(4) Move valve to and from the indicator. The total dial indicator reading should not exceed 0.432 mm (0.017 inch). Ream the guides for valves with over- size stems if dial indicator reading is excessive or if the stems are scuffed or scored.

VALVES
Inspect the remaining margin after the valves are refaced (Fig. 17). Valves with less than 1.190 mm (0.047 inch) margin should be discarded.
VALVE SEATS
(1) When refacing valve seats, it is important that the correct size valve guide pilot be used for reseat- ing stones. A true and complete surface must be obtained.
Fig.17IntakeandExhaustValves
1 - MARGIN 2 - VALVE SPRING RETAINER LOCK GROOVE 3 - STEM 4 - FACE
(2) Measure the concentricity of valve seat using a dial indicator. Total runout should not exceed 0.038
mm (0.0015 inch) total indicator reading.(3) Inspect the valve seat with Prussian blue to determine where the valve contacts the seat. To do this, coat valve seat LIGHTLY with Prussian blue then set valve in place. Rotate the valve with light pressure. If the blue is transferred to the center of valve face, contact is satisfactory. If the blue is trans- ferred to the top edge of valve face, lower valve seat with a 15° stone. If the blue is transferred to bottom edge of valve face raise valve seat with a 60° stone. (4) When seat is properly positioned the width of valve seats should be 1.016-1.524 mm (0.040-0.060
inch).VALVE SPRING INSPECTION
Whenever valves have been removed for inspection, reconditioning or replacement, valve springs should be tested. As an example the compression length of the spring to be tested is 1-5/16 inch. Turn table of Universal Valve Spring Tester Tool until surface is in line with the 1-5/16 inch mark on the threaded stud. Be sure the zero mark is to the front (Fig. 18). Place spring over stud on the table and lift compressing lever to set tone device. Pull on torque wrench until ping is heard. Take reading on torque wrench at this instant. Multiply this reading by 2. This will give the spring load at test length. Fractional measurements are indicated on the table for finer adjustments. Refer to specifications to obtain specified height and allowable tensions. Discard the springs that do not meet specifications.
