12ENGINE 36 DESCRIPTION AND OPERATION CYLINDER HEAD FLOW 1.Cast-in groove between cylinder head and camshaft carrier 2.Rocker shaft flow 3.Lash adjuster supply channels (10 off) 4.Non-return valve 5.Chain lubrication jet supply6.Oil return from vacuum pump 7.Oil supply to timing chain tensioner adjuster 8.Oil supply to vacuum pump 9.Oil supply hole to camshaft sprocket and timing chain Oil passes to the cylinder head from the cylinder block via a non-return valve which is included to prevent oil draining away from the lash adjusters when the engine is switched off. Oil is passed to a cast-in groove between the top of the cylinder head and the camshaft carrier. The part of the channel on the top left hand side of the cylinder head has ten cross-drillings which supply oil to the hydraulic lash adjusters and finger followers. Lubrication oil fed to the lash adjusters passes up through the lash adjuster body and into the socket of the finger followers. The oil exits the finger followers through a small hole to lubricate the surfaces between the camshaft lobes and rollers.
ENGINE 37 DESCRIPTION AND OPERATION An additional tapping is included at the front left hand side of the cylinder head to supply oil to the chain lubrication jet and a through hole near the front centre of the cylinder head allows a passage of oil through from the cast-in groove to lubricate the timing chain and camshaft sprocket. At the centre front of the cylinder head, the cast-in groove channels oil into the rocker shaft via the front rocker shaft fixing. Oil flow through the rocker shaft and clearance around the rocker shaft fixings provides oil feed to the camshaft bearings. A tapping towards the right hand side of the cylinder head diverts oil supply from the cast-in groove down to a stub pipe which attaches to a feed line to the vacuum pump. An hydraulic tensioner is located below the vacuum stub pipe which receives oil through a small hole in the side of the tensioner body to force a plunger against a plastic faced adjuster shoe for timing chain tensioning. Oil from the vacuum pump is returned to the a port in the timing chain cover via a short hose which connects to stub pipes at both ends using spring clips.

12ENGINE 2 REPAIR 13.Position camshaft in camshaft carrier. 14.Check end-float of camshaft using a DTI. Camshaft end-float = 0.06 to 0.16 mm (0.002 to 0.006in). 15.Renew components as necessary to achieve correct end-float. CAUTION: Cylinder head and camshaft carrier are machined together as an assembly. If bearing surfaces in either component are found to be damaged, complete assembly must be replaced. NOTE: The procedure for checking camshaft bearing clearances is covered in Td5 Engine Overhaul section - Cylinder head - overhaul.Refit 16.Using a suitable cleaning solvent, clean mating faces of cylinder head and camshaft carrier. 17.Blow out all oilways and waterways. 18.Ensure threaded holes in cylinder head and camshaft carrier are clean and dry. CAUTION: Support each end of the cylinder head on blocks of wood. With camshaft carrier bolted down some valves and the injector nozzles will protrude from the face of cylinder head. 19.Fit new adjusting screws fully into rocker arms. Fit new lock nuts to screws but do tighten. CAUTION: Ensure screws are correct for type of rocker arms fitted. Replacement screws for Engine Serial No. Prefixes 15P to 19P have a centre punch mark adjacent to the adjusting screw slot. These screws are not interchangeable with those fitted to Engine Serial No. Prefixes 10P to 14P. 20.Lubricate cams and bearing journals on camshaft, cylinder head and camshaft carrier with clean engine oil. 21.Position camshaft in cylinder head with the timing pin hole in the vertical position. 22.Apply an even film of sealant, Part No. STC 4600 to camshaft carrier face as shown and spread to an even film using a roller. CAUTION: Ensure sealant does not block oilways (arrowed) or contaminate camshaft bearings. Assembly and bolt tightening must be completed within 20 minutes of applying sealant. 23.Fit camshaft carrier ensuring that it is correctly located on dowels. 24.Fit and lightly tighten camshaft carrier bolts.
