Exhaust camshaft bearing cap tightening sequence - 1.3 litre

B DO NOT use the timing marks for the S engines when installing the camshafts and gears

28 Install the exhaust camshaft bearing caps (except the right-hand cap) in numerical order with the arrows pointing toward the timing belt end of the engine.

29 Tighten the bearing cap bolts uniformly and alternately, in several stages, until the caps are snug with the cylinder head. Do not tighten the bolts to the full torque setting at this stage.

30 Remove the service bolt from the intake camshaft gear.

31 Apply a thin coat of RTV sealant to the intake camshaft right-hand bearing-cap-to-cylinder-head mating surface. Note: The cap must be installed immediately or the sealer will dry prematurely. Install the cap and tightenthe two bearing cap bolts uniformly and alternately, in several stages, until the cap is snug with the cylinder head. Do not tighten the bolts to the full torque setting at this stage.

32 Install the housing plug to its location in front of the intake camshaft.

33 Following the recommended sequence (see illustration), tighten all the intakecamshaft bearing cap bolts uniformly to the torque listed in this Chapter's Specifications.

34 Lubricate the lips of a new exhaust camshaft oil seal with engine oil or multi-purpose grease and install the seal in the cylinder head. Push the seal fully into the recess in the head.

35 Apply a thin coat of RTV sealant to the exhaust camshaft right-hand bearing-cap-to-cylinder-head mating surface. Note: The cap must be installed immediately or the sealer will dry prematurely. Install the cap and tightenthe two bearing cap bolts uniformly and alternately, in several stages, until the cap is snug with the cylinder head. Do not tighten the bolts to the full torque setting at this stage.

36 Following the recommended sequence

(see illustration), tighten all the exhaustcamshaft bearing cap bolts uniformly to the torque listed in this Chapter's Specifications.

37 Install the timing belt sprocket on the exhaust camshaft and tighten the bolt to the torque listed in this Chapter's Specifications. Prevent the camshaft from turning by holding it with a spanner on the hexagonal section.

38 Install the timing belt (see Section 5).

39 The remainder of refitting is the reverse of the removal procedure.

1. 6 litre 4A-FE engine

Note: Before beginning this procedure, obtaintwo 6x1.0 mm, bolts 16 to 20 mm long. They will be referred to as service bolts in the text.
