Lubrication Problems and Remedies

Lubrication Problems and Remedies Points : Lubrication Problems and Remedies, High Oil Consumption, Low oil pressure, Lubrication System Problem, Problems in internal combustion engines ic engine They include:
1. High oil consumption (oil must be added to engine frequents).
2. Low oil pressure (gauge reads low indicating light glows of abnormal engine noises).
3. Defective indicator or gauge circuit (inaccurate operation or readings). High Oil Consumption High oil consumption is caused by external oil leakage out of the engine or by internal leakage of oil into the combustion chambers. If the vehicle owner must frequently add oil to the engine, this is a symptom oil high oil consumption. External oil leakage External oil leakage is easily detected as darkened, oil-wet: areas on all around the engine. Oil may also found is small puddles under the vehicle. Leaking gaskets or seals are usually the source of external engine oil leakage. Internal oil leakage Internal oil leakage shows up as BLUE SMOKE coming out the exhaust for exhaust. For example, if the engine piston rings and cylinders are badly worn, oil can enter the combustion chambers and be burned during combustion.

Do not confuse black smoke (excess fuel in cylinder) and white smoke (water leakage into gasoline engine cylinder) with the blue smoke caused by motor oil. Low oil pressure Low oil pressure is indicated when the oil indicator light glows, oil gauge reads low, or when the engine bearings rattle. You must make sure of the actual problem.
The most common causes of low oil pressure are;
1. Low oil level (oil not high enough in pan to cover oil pickup).
2. Worn connecting rod or main bearings (pump cannot provide enough oil volume).
3. Thin or diluted oil (low viscosity or gasoline in oil)
4. weak or broken pressure relief valve spring (valve opening too easily).
5. Cracked or loose oil pump pickup tube (air being pulled into oil pump).
6. Worn oil pump (excess clearance between rotor or gears and housing).
7. Clogged oil pickup screen (reduced amount of oil entering pump).
