Ford 2.4, 2.8 and 2.9 litre V6 engines Manual

Ford 2.4, 2.8 The V6 engine fitted to the Granada is only available in fuel-injected form. Mechanically, the design of the engine is well-established, and it is improved by the latest fuel, ignition and engine management systems.

Ford 2.9 litre V6 engines The combined crankcase and cylinder block is made of cast iron, and houses the pistons, crankshaft and camshaft. The sump is attached to the bottom of the crankcase and the cylinder heads to the top.

The cylinder heads are of the crossflow design, the inlet manifold being located between them and the exhaust manifolds being on the outboard sides. The overhead valves are operated by tappets, pushrods and rockers from the centrally located camshaft. Camshaft drive is by gears (2.8 litre) or chain (2.4 & 2.9 litre).

Ford Service Manual The crankshaft runs in four main bearings. Endfloat is controlled by thrust flanges on the No 3 bearing shells. The connecting rods are selected so that all are in the same weight class. Aluminium alloy pistons are used. The gudgeon pins are an interference fit in their connecting rods.

The lubrication system is of the usual wet sump, pressure fed type, with a full-flow disposable canister oil filter. The oil pump is driven by a shaft which engages in the bottom of the distributor drivegear.

Major operations possible with the engine in the vehicle
The following operations can be carried out without removing the engine, although some work will be easier and quicker with the engine removed.

1. Removal and refitting of the cylinder heads
2. Removal and refitting of the sump and oil pump
3. Removal and refitting of the timing gears
4. Removal and refitting of the pistons, connecting rods and big-end bearings
5. Renewal of the engine mountings
6. Removal and refitting of the flywheel
7. Renewal of the crankshaft front and rear oil seals
8. Removal and refitting of the camshaft (after removal of the cylinder heads, tappets and timing gears)

Camshaft and bearings - examination and renovation
If there is excessive wear in the camshaft bearings they will have to be renewed. As the fitting of new bearings requires special tools this should be left to your local Ford dealer. The camshaft may show signs of wear on the bearing journals or cam lobes. The main decision to take is what degree of wear necessitates renewing the camshaft, which is expensive. Scoring or damage to the bearing journals cannot be removed by regrinding; renewal of the camshaft is the only solution.

The cam lobes may show signs of ridging or pitting on the high points. If ridging is slight then it may be possible to remove it with a fine oil stone or emery cloth. The cam lobes, however, are surface hardened and once the hard skin is penetrated wear will be very rapid.

Excessive endfloat of the camshaft may be remedied by fitting a thicker spacer and/or thrust plate - see Specifications. Excessive backlash in the camshaft drive
gears (timing gears), which will have been noticed before dismantling by virtue of the characteristic growling noise, can only be remedied by renewing the gears.
