in .) . Turn the engine in the direction of rotation until the valves in one cylinder are "rocking" . Then turn the engine one turn more and adjust the valves for this cylinder . 14 . Valve clearance cold/warm engine 0 .30 mm ( .01181 Repeat the procedure for the remaining cylinders . 2003 12 . Tighten the two guide screws p/n 884840 in the block and install the cylinder head gasket with the marking "Top" facing upwards . Install the cylinder head . Make sure that the contact surface for the cylinder head bolts are free from paint . Should there be paint on the bolts, there is always the risk of having an insufficiert tightening force in the bolt joint with subsequent leakages as a result .
NOTE! The bolts are phospated, therefore do not clean them with a steel-brush . Coat the cylinder head bolts with molybdenum disulphide and tighten them in accordance with the diagram, first to 20 Nm (2 .0 kpm/14.7 ft .lbs) and then to 70 Nm (7 .0 kpm/51 .6 ft.lbs). Adjusting the fuel injection pump location with shims 15 . if the same block camshaft and fuel Injection pumps are used when assembling, the fuel injection pump must be installed in their original positions and with the same shim thickness as earlier . The so called soft shims, always being installed against the block, must be replaced against new ones .
Carefully clean the contact surfaces between the block and the fuel injection pumps and install shims with thickness equal to the sum of the marking on the block and that on the fuel injection pump, (4) earlier marking . Example : The block marking 4 (= 4 tenths of a millimeter) ( .015748 in .) The pump marking 4 (= 4 tenths of a millimeter) ( .015748 in .) Total amount of shims = 0 .8 mm ( .031496 in .) In this case select two soft shims 0 .2 and 0 .3 mm ( .011811 in .) . Place the hard shim between the two soft ones and install the pump . NOTE! Never install a hard shim together with another hard shim or against the block or the fuel injection pump .
Hard shims are available in thicknesses 0 .3, 0 .6 and 0 .9 mm ( .011811, .02362, .035433 in . respectively) . Soft shims are available in thicknesses 0 .2 and 0 .3 mm 13 . Install the push rods and the rocker arm bridge, push on new rubber rings to the oil pipe which is fitted at the same time as the rocker arm bridge . ( .007874 and .011811 in .) .
