Three-piece exhaust manifold (typical example) (1) Exhaust manifold gasket (2) Packing material (3) Shields (4) Studs (5) Spacer (6) Washer (7) Spiralock nut (8) Stud (1) Exhaust manifold gasketNote: The exhaust manifold gaskets have tabs. The tabs should point downward to the oil pan.
Excessive use of sealant can cause damage to components.To avoid component damage use only the amount of sealant necessary for the application.
Use the following procedure during assembly of the three-piece exhaust manifold to the cylinder block.
Mounting surfaces should be clean, and dry. In addition, mounting surfaces should be free of any other foreign matter.
Apply engine oil to the female ends of the exhaust manifold before assembly. Apply 2P-2333 High Temperature Sealer to the outside diameter of the male ends of the exhaust manifold. Remove any excess sealer from the assembled joint. (2) Position the packing material so that the split line of the packing material is at the 12:00 o'clock position. (3) Position the shields so that the gaps of the shields are positioned at 3:00 o'clock and at 9:00 o'clock. Do not pinch the packing material when you install the shields. Position the exhaust clamps as the clamps are shown in Illustration 1.Use the following procedure to assemble the shield and clamp over the joint in the exhaust.
Torque the clamps to 5 1 N m (44 9 lb in).
Again tighten both of the clamps to 16 1 N m (142 9 lb in).
Again tighten both clamps after the hot test to 16 1 N m (142 9 lb in). (4) Apply 5P-3931 Anti-Seize Compound to the stud threads. Assemble the studs with the letter "X" outward. Tighten the studs to the following torque. ... 35 5 N m (26 4 lb ft) (5) Spacer (6) Washer (7) Spiralock nut
