Many major engine repairs can be performed without removing the engine from the vehicle.
Before performing work, wash the engine compartment and the car body with a special oil-washing compound. This will make your job easier and reduce the chance of dirt getting inside the engine.
Depending on the work ahead, it may be convenient to remove the hood for easier access to the engine from all sides (in this case, please contact chapter 11). To protect the wings from damage to the paint, cover them with a thick cloth.
Without removing the engine, it is possible to replace most seals and gaskets, the failure of which causes leakage of liquids or gases. These include gaskets for the cylinder head, manifolds, sump, crankshaft and camshaft seals, etc.
Without removing the engine from the car, you can remove for repair almost all external devices, such as water and oil pumps, starter and generator, elements of the ignition system and fuel system
Since the cylinder head can be removed from the engine without removing it from its place, all systems located on it can be repaired - manifolds, valves, rocker arms, camshafts and their drive.
In exceptional cases due to lack of equipment or time, it is even possible to perform a medium engine repair with the replacement of pistons, piston rings, connecting rods and liners, although this is not recommended.
