General information about 1.1/1.3 l engines (VW Golf 1)

The Golf and Jetta models can be equipped with small-displacement engines of 1.1 l (1043 cm³) and 1.3 l (1272 cm³), which are identical in design.

The engine has a valve mechanism with an overhead camshaft (OHC). The camshaft is driven from the crankshaft by a toothed belt. The crankshaft rotates in five main bearings; the middle bearing liners have thrust surfaces and perform the functions of thrust half rings.

The oil pump is housed in a separate housing bolted to the front of the cylinder block and is driven directly by the crankshaft.

The cooling pump is located at the front of the cylinder block and is driven by the camshaft timing belt.

The cylinder head is designed according to the principle of "through flow" of the working mixture, i.e. the intake and exhaust manifolds are located on opposite sides of the head (the exhaust manifold is located in front, and the intake manifold is located at the rear relative to the car).

The camshaft rotates in three bearings located on the cylinder head and acts on the valves using levers resting on adjusting bolts with ball heads.

The ignition distributor is located horizontally at the rear of the cylinder head and is driven directly from the camshaft.

Most repair operations (for example, removing the camshaft drive belt, cylinder head, cooling pump) can be done without removing the engine from the car. The engine must be removed only to carry out major repair work on the cylinder block.
