Many major repair operations can be accomplished without removing the engine from the vehicle. Clean the engine compartment and the exterior of the engine with some type of pressure washer before any work is done. A clean engine will make the job easier and will keep dirt out of the internal areas of the engine. Depending on the components involved, it may be a good idea to remove the hood to improve access to the engine as repairs are performed (refer to Chapter 11 if necessary.) If oil or coolant leaks develop, indicating a need for gasket or seal replacement, the repairs can generally be made with the engine in the vehicle. The oil pan gasket, the cylinder head gaskets, intake and exhaust manifold gaskets, timing chain cover gaskets and the crankshaft oil seal are all accessible with the engine in place. Exterior engine components, such as the water pump, the starter motor, the alternator, the distributor and the fuel injection components, as well as the intake and exhaust manifolds, can be removed for repair with the engine in place. Since the cylinder heads can be removed without removing the engine, valve component servicing can also be accomplished with the engine in the vehicle. Replacement of, repairs to or inspection of the timing chain and sprockets and the oil pump are all possible with the engine in place. In extreme cases caused by a lack of necessary equipment, repair or replacement of piston rings, pistons, connecting rods and rod bearings is possible with the engine in the vehicle. However, this practice is not recomended because of the cleaning and preparation work that must be done to the components involved.
