Car engine repair VW Golf 1, diesel

Description of diesel engine design
One of the laws of physics states that the amount of energy during the combustion of an air-fuel mixture is greater, the more the mixture was compressed before it ignited. This...

Separate engine components
Based on the theory, now we will take a closer look at the individual components of the engine, and then we will move on to maintenance and repair. Engine block The diesel engine...

Running in a new engine
During the first 1000 km, the engine parts must run in to each other. This should be done at low load and at low speeds. The subsequently developed engine power and its service...

Uncontrolled increase in speed
Previously, a typical engine damage was an uncontrolled increase in the number of revolutions, work "peddling" especially for older models (1.5 l). Even serviceable engines then...

Measurement of compression in cylinders
Compression measurement in the engine's cylinders will give information on whether the valves and piston rings are well sealed. The power, cold start performance, oil and fuel...

Turning the crankshaft of the engine
To carry out some work on the engine, it is sometimes necessary to turn the crankshaft manually. The easiest way to do this is as follows. Wrench for the central nut of the...

Top dead center search
To carry out various work on the engine and fuel pump, the piston in the first cylinder must be at top dead center (TDC). This means that it must be at the point of maximum rise....

Valve clearance
Due to the heating of the engine, individual parts of the valves expand and lengthen. Therefore, there must be a small gap between the camshaft and the cup pushers. Only then can...

Adjustment of valves
To adjust the valves at the top, adjusting washers of various thicknesses are inserted into the cup pushers. From the size of the gap (too big or too small) depends on which plate...

Toothed belt adjustment
The timing belt in a diesel engine is of great importance. It drives the camshaft, high pressure fuel pump, oil pump and brake booster vacuum pump. If the belt breaks or jumps one...

Checking the condition and tension of the toothed belt
Removing the toothed belt cover The purpose of the cover is to prevent foreign particles from getting inside, as this can damage the operation of the toothed belt. Dismantling is...

Toothed belt tension
First of all, pay attention to the section " Toothed belt adjustment ", because tensioning the toothed belt is a labor intensive job. There is one more problem. While the engines...

Toothed belt replacement
In this case, you should first read the instructions under the heading " Toothed belt adjustment ". Two sets of probes are used, a VW 2065 or 2065 A adjusting ruler and a 2064...

Removal and installation of a head of cylinders
Since in order to carry out this work it is necessary to dismantle the toothed belt, it is imperative to take into account the requirements in the section " Toothed belt...

Choosing the Right Cylinder Head Gasket
In a diesel engine, cylinder head gaskets of various thicknesses are installed. The thickness of the gasket depends on which tolerance the installed pistons tend to: to the top or...

Removing the camshaft
If the camshaft is removed from the installed cylinder head, then the dismantling of the toothed belt is added to the above works, as well as the regulation of the start of the...

Removing cup pushers
Remove camshaft. Use a felt-tip pen to number the cup pushers so that they can be re-inserted into the same guides during installation. Pull pushers upwards. For valve stem seal...

Removing valves
To dismantle the valves, their springs must be compressed. Since the dual valve springs are under high pressure in a diesel engine, we recommend the following tool for this job,...

Validation of valves and heads
Old valves can later be used if: their seats are not so worn that the valve plate inserted into the cylinder head is located more than 1.5 mm below the surface of the cylinder...

Replacement of seals (valve stem seals) valve stems
Writing off the course of work, we proceed from the fact that the cylinder head is removed and the valves are removed (see previous section). The old valve stem seal should be...

Additional valve lapping
Worn pistons, piston rings and cylinders, as well as leaky valves can be the causes of poor compression pressure. If the valves are still in good condition, it is enough to do an...

Engine leak test (oil leak)
Heavy oil leaks are found in the diesel engine at the following locations. Rear crankshaft seal near the flywheel. Oil comes out at the junction between the engine and gearbox....

Engine damage
Depending on the defect, the diesel engine can be brought back to serviceable condition in various ways. The older your car is and the more the body has suffered from rust, the...

Dismantling the engine
Preparatory work The engine, together with the gearbox, is removed upwards. This will require a chain hoist that can be stably installed at a sufficient height. It is also...

Disconnecting the engine from the gearbox
For diesel models "Golf" "Diesel" manufactured before November 1978, the engine can only be disconnected from the gearbox when the crankshaft is in a certain position. Remove the...

Engine installation
Installation is carried out in the reverse order ( compared to withdrawal ). All self-locking nuts should be replaced. Lubricate the disengaging clutch and gearing of the drive...
