2. Remove the intake manifold, after draining the fluid from the cooling system.
3. Remove both exhaust manifolds.
4. Remove the rocker arms and tappets.
5. Make a copy of the gasket out of cardboard, outlining its contours. Punch holes for the bolts, into which you insert the unscrewed bolts, so that when assembling they can be screwed back into their original places (see photo). Show the front of the engine on the cardboard copy.
6. Loosen the head bolts 1/4 turn per stroke so that they can be unscrewed by hand. Unscrew the bolts in the reverse order of tightening.
7. Remove the heads. If the head cannot be removed, then dislodge it with hammer blows through a wooden block. Place the head on the wooden blocks.
8. The procedure for disassembling the cylinder head is discussed in Chapter 2B.
9. Thoroughly clean the separating surfaces of the cylinder head and block.
10. Cover the openings under the pushers. Carefully (taking care to prevent dirt from getting into the holes) scrape off carbon deposits and gasket material residues, and finally rinse the head with acetone.
11. Check the split surfaces of the cylinder head and block for burrs, chips, dents and other damage. Minor damage can be eliminated by cleaning it with a file; in case of serious damage, the head or block must be re-ground. Blow out all channels and holes with compressed air.
12. Tap all threaded holes (see photo).
13. Place the new gasket on the cylinder block, aligning it with the pins.
Caution! If a steel gasket is used, apply a thin coat of K8W Copper Coat sealant to both sides of the gasket. Steel gaskets are installed with the convex side facing up. Composite gaskets should be installed without sealant.
14. Carefully install the head onto the cylinder block without disturbing the position of the gasket.
15. Lubricate the thrust surfaces of the bolt heads with engine oil.
16. Screw the cylinder head bolts back into their original positions by hand. Tighten the bolts to the specified torque Technical data, in the given sequence (see photo).
17. Then assembly is carried out in reverse order.
