Engine Lubrication Problems – Lack Of Oil, Causing Engine Wear
To start with, a poor maintenance routine is by far one of the biggest causes of, engine lubrication problems.
Not only that, extended oil change intervals, are responsible for low engine oil levels. And subsequent, engine lubrication problems.
As a result, excessive engine oil sludge develops. And, will eventually clog the engine’s oil pump pickup screen, oil filter and oil galleries.
So, engine lubrication problems begin, anytime there is a lack of lubrication. And, will only get worse over time.
Every engine needs oil between its moving parts, not only to reduce friction, but also to carry away heat. Because, oil is the primary means, by which the rod and main bearings as well as the pistons, are cooled.
So, any reduction in oil flow, may cause these parts to run hot, gall and seize. And, detergents contained in fresh oil, will accelerate the clogging of oil pump screens and oil filters. Consequently, by loosening accumulated sludge. As a result, volumes of engine sludge and dirty engine oil, can easily clog today’s compact oil filters.
Quite often the oil filter bypass valve, will open during cold engine starts. As a result, more sludge and dirt, will pass into the engine bearings and reciprocating parts. Then, engine life is drastically shortened, when operated at extreme temperatures and loads.
The Initial Symptoms, Of Engine Lubrication Problems Are:
- A noisy engine, during cold start-up.
- A oil pressure gauge, that rise very slowly.
- Engine ticking noise at all speeds.
Low Oil Pressure Causing Engine Lubrication Problems
So, low oil pressure, is often a contributing factor in, engine failures. The hidden cause may be, a worn oil pump and/or excessive clearances in the main and rod bearings. Most of the time, as a result, of high mileage wear or neglect.
Oil Starvation Causing Engine Lubrication Problems
Oil Starvation, Is Almost Always Fatal To Any Engine, And Is Usually The Result Of:
So, there are Coolant Mixed With Oil – In The Lubrication System – Cleaning Tips.
Bearings that have been damaged, as a result of engine lubrication problems, will be shiny and worn. Usually, where the crankshaft journal wiped away, the bearing material. (OHC) engines, are even more vulnerable to oil starvation and low oil pressure problems.
Due to, the cam and valve train being, farther away from the oil pump. Also, when an (OHC) engine is first started, it takes awhile for oil pressure to reach the camshaft. So, if the oil viscosity is too heavy. Then, it may delay the arrival of oil long enough, to seize the camshaft.
For this reason, most vehicle manufacturers recommend using, a 5W-30 oil in late model (OHC) engines year round. So, filling the crankcase, with the recommended viscosity oil, can prevent engine lubrication problems. A low oil level, can also be the result of neglect, oil leakage and/or oil burning.
Engine Oil Burning
Your Engine May Be Burning Oil, If You Have:
- Oil-fouled spark plugs.
- A heavy buildup of black wet deposits, on the backs of the intake valves.
- Grey exhaust smoke.
Ways Oil Can Enter The Combustion Chamber Are:
So, if oil burning is due to worn or broken rings or worn cylinders, the engine will have low compression. The only cure here, is to bore or hone the cylinders, and replace the worn or broken piston rings. Most often it requires, new valve guides.
In addition, new valve stem seals, can often reduce oil burning. Also, helping reduce engine lubrication problems.
Engine Oil Leaks
Any evidence of oil leakage, would tell you that gaskets and seals, may need to be replaced.
Common Places For Oil To Leak Are:
- Front or rear crankshaft seals
- Oil pan gasket
- Valve cover gaskets
- Intake manifold gaskets
Gaskets and oil seals should be replaced, if worn or leaking or whenever removed, during servicing.
Replacement is simple, but some engine dismantling, may be necessary to reach them. Check for a plugged oil filter and/or a missing air filter or oil filler cap. However, the hidden cause here, may be just not changing the oil often enough.
In Summary: Engine Lubrication Problems
So, regular maintenance might seem pricey, but it’s also critical to keeping your engine, in good working condition. Finally, be sure to keep up, with routine oil changes and other maintenance, to avoid engine lubrication problems.
Thank You !!
