Order of execution
1. Inspect the engine from top to bottom.
2. Slightly oily spots are nothing to worry about - all engines are slightly oily from time to time «sweat» grease.
3. But the reason for the appearance of oil stains under a parked car and obvious oiling should be studied.
4. Wash the engine with a special detergent and a steam jet.
5. After a test drive of several kilometers, check to see if oil is coming out.
Possible Leak Locations
Here we have listed the places where oil can leak in an Audi engine:
- Gaskets, crankshaft, camshaft (s) shaft (ov) and intermediate shaft in a four-cylinder engine. These places are covered by the toothed belt cover.
- Cylinder head cover gaskets.
- Cylinder head gasket.
- Oil pressure switch.
- Oil filter gasket.
- Oil cooler gasket (behind the filter).
- Crankcase gasket.
- Gasket behind the crankshaft (oil leaks into the engine and gearbox housing connector).
Tip: The so-called self-service steam jet car washes can be used to clean the engine inexpensively. In case of severe contamination, it is recommended to pre-spray the engine with a special detergent and wait a little for it to work. Be sure to bring your work clothes!
Running in a new engine
For the first 1000 km, sliding engine parts (pistons and cylinders, plain bearings and shafts) must «get used to» to each other. This should take place at low loads, i.e. at low speeds. The engine power in the future and its service life depend on this. That's why:
1. Do not give full throttle; with an automatic transmission, avoid the position of full throttle and depressing the accelerator pedal all the way. Maximum number of revolutions: 4200 rpm!
2. Raise the speed only when the engine is warm and up to the specified 4200 rpm; switch earlier in cold weather.
3. When running from 1000 to 1500 km, gradually accelerate the engine to maximum speed or to the maximum allowable speed.
Tip: What has been said here about the new engine also applies to the overhauled power plant, which - in experience - is sensitive to the wrong driving style.
