Three-piece exhaust manifold (typical example)
(4) Gasket
(6) Spacer
(7) Washer Note: The exhaust manifold gaskets have tabs. The tabs should point downward to the oil pan.Use the following procedure during assembly of the three-piece exhaust manifold to the cylinder block:
Excessive use of sealant can cause damage to components.To avoid component damage use only the amount of sealant necessary for the application.
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. Do not apply the sealer at the tip of the male ends. Remove any excess sealer from the assembled joint. Note: Apply 4C-5599 Anti-Seize Compound to the threads of the taperlock studs. Assemble the taperlock studs with the letter X outward. (1) Torque for the taperlock studs ... 35 5 N m (26 4 lb ft) (2) 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. (3) Position the packing material so that the split line of the packing material is at the 12:00 o'clock position. Use the following procedure to assemble the shield and clamp over the joint in the exhaust (5):
Tighten the two clamps to 5 1 N m (45 9 lb in).
Again tighten the two clamps to 16 1 N m (140 9 lb in).
Illustration 2 g00566145Note: Apply 4C-5599 Anti-Seize Compound to the threads of the locknuts. Tighten the locknuts in the numerical sequence that is shown above in Illustration 2. (8) Torque for twelve locknuts ... 55 5 N m (41 4 lb ft)Note: Do not start the engine until the sealant in the exhaust manifold joints has air dried for 24 hours.
