How to Know if the Oil Pump in Your car is Failing
The oil pump plays a critical role in maintaining proper lubrication and ensuring that your engine's moving parts are adequately supplied with oil. If the oil pump starts to fail, it can lead to serious engine problems. Here are some signs that might indicate a failing oil pump:
Low Oil Pressure Warning Light. Many modern vehicles are equipped with an oil pressure warning light on the dashboard. If this light comes on and stays illuminated while you're driving, it's a clear indication of low oil pressure, which could be caused by a failing oil pump.
Engine Noise. A failing oil pump can lead to insufficient oil pressure, causing metal-to-metal contact between engine components. This can result in increased engine noise, often described as ticking, knocking, or tapping sounds. The noise might be most noticeable at startup or during acceleration.
Poor Engine Performance. Insufficient lubrication due to a failing oil pump can lead to decreased engine performance. You might notice reduced power, sluggish acceleration, or difficulty maintaining consistent speed.
Oil Warning Light. Some vehicles have a separate oil warning light that indicates low oil level. However, this could also be related to oil pump failure, as the pump's inability to circulate oil might lead to decreased oil pressure and subsequent oil consumption.
Overheating. If the oil pump is failing and not providing adequate lubrication, it can lead to increased friction and heat within the engine. This can contribute to engine overheating.
Drop in Oil Pressure Gauge Reading. If your vehicle is equipped with an oil pressure gauge, you might notice a sudden drop in the pressure reading on the gauge. This can be an early indication of oil pump problems.
Consistent Check Engine Light. A failing oil pump and low oil pressure can trigger the vehicle's onboard diagnostics system, causing the check engine light to illuminate. Be sure to retrieve any stored error codes using a diagnostic scanner.
If you observe any of these signs, it's crucial to address the issue promptly to prevent potential engine damage. Continuing to drive with a failing oil pump can lead to serious consequences, including engine seizure.
If you suspect that your oil pump is failing, it's recommended to have your vehicle inspected by a qualified mechanic. They can perform diagnostic tests to determine the exact cause of the issue and recommend appropriate repairs. Regular maintenance and oil changes can also help prevent oil pump problems by ensuring a clean and well-lubricated engine.
How to Test if the Oil pump is Failing
Testing the oil pump's functionality usually requires specialized equipment and expertise. However, there are some basic steps you can take to help diagnose potential issues with the oil pump. Keep in mind that if you suspect your oil pump is failing, it's best to consult a qualified mechanic for a thorough diagnosis. Here's what you can do:
1. Check the Oil Pressure Gauge. Start your car and let it idle. Observe the oil pressure gauge on your dashboard. If the gauge indicates very low or zero oil pressure, it could be a sign of a failing oil pump. However, keep in mind that a faulty oil pressure sensor could also cause inaccurate readings.
2. Use a Manual Oil Pressure Gauge. If you're comfortable working under the hood and have the necessary tools, you can temporarily install a manual oil pressure gauge to get an accurate reading. This involves disconnecting the oil pressure sending unit and attaching the manual gauge. Start the engine and compare the readings from the manual gauge to the dashboard gauge. If there's a significant difference or consistently low pressure, it could indicate an oil pump problem.
3. Inspect for Leaks. Check for any oil leaks around the oil pump and oil filter housing. Leaks could result from a failing pump or worn seals.
4. Check for Engine Noise. Listen for any unusual noises coming from the engine, such as knocking, tapping, or rattling. These noises could be indicative of insufficient lubrication due to oil pump issues.
5. Perform an Oil Pressure Test. This test requires specialized equipment and is best done by a professional mechanic. It involves connecting a pressure gauge to the engine's oil pressure port to measure the actual oil pressure while the engine is running at different RPMs. A significant drop in pressure between idle and higher RPMs could suggest an oil pump problem.
6. Check for Contaminated Oil. Inspect the engine oil on the dipstick. If you notice metallic particles, sludge, or a thick consistency, it could indicate oil circulation problems caused by a failing oil pump.
7. Inspect the Oil Filter. Remove the oil filter and cut it open to inspect for debris or metal shavings. These could be signs of insufficient oil flow and potential pump failure.
Remember, diagnosing oil pump issues can be complex and requires expertise. If you suspect your oil pump is failing, it's advisable to consult a professional mechanic. They have the necessary tools and knowledge to perform accurate diagnostic tests and recommend appropriate repairs. Ignoring oil pump problems can lead to severe engine damage, so it's important to address the issue promptly.
Is Your Car Shaking When Idle? Here's What You Need to Know
Car shakes when idle, the vibration is so extreme that it causes the entire car to shakes even when the car does not move and stay idle.
Why car shakes at idle?
If car shakes when idle the reason is that one of the cylinders is misfiring. For the normal engine to run smoothly the engine cylinder must fire properly, the firing of each cylinder must be in the correct sequence. If one of the cylinders is not firing according to the normal firing order in sequence the engine will be out of balance which will result to engine extreme vibration that is enough to cause the entire car shaking at idle.
But that is not the real problem here, the real problem is why the cylinder misfiring. The reasons for the engine cylinder to misfire are bad spark plugs, bad spark plug wires or a worn distributor cap. Any of the above reasons can cause the firing of the air/fuel mixtures inside the cylinder. Another possibility is that the valves are burned. If the valve is burned the compression of the cylinder will become abnormal and as a results engine misfiring occurs.
Possible cause of car shaking at idle
Engine misfiring on one of the cylinder
What to do when there is excessive car shakes at idle?
Replace Spark Plug
To begin fixing the problem first is to replace the spark plug and the spark plugs wires usually this will fix the problem of engine misfiring.
Replace Distributor Cap
If after the replacement the car still shakes when idle the next thing to replace is the distributor cap. You can do the work by yourself by checking on the service manual that covers your car model or you may bring the car to the shop for tune-up.
If after then cap was replaced and the problem still occurs then the problem is a burned valve, in this case, confirm with the shop mechanic the problem and repair if necessary.

What Would Cause an Engine to Lose Power?
What would cause an engine to lose power? Well, several reasons would cause an engine to lose power like the fault on the ignition system, fuel system, or clogged catalytic converter.
Possible cause of an engine to lose power
Clogged catalytic converter
If the top speed of your car is significantly 15 miles less than it was before, the problem is a clogged catalytic converter.
The purpose of the catalytic converter to clean the unburned gasses that pass through in the exhaust system, if the catalytic converter is clogged the exhaust gasses will not freely pass and will be restricted through the catalytic converter, now the faster the car the harder it is for the unburned gasses to get past the catalytic converter all the way to the tailpipe and back pressure to the engine happens that causes the engine to lose power. The harder the accelerator pedal is pressed the more back pressure in the engine, therefore, the car will not reach the top speed.
Bad spark plug or spark plug wires
If the engine runs roughly especially during idle, then the problem is related to the fuel system specifically a bad spark plug or spark plug wires. If the spark plug or spark plug wires are bad there will be no spark in the combustion chamber and the engine will misfire.
Clogged fuel injector
If the above condition is not met then the possible problem is the fuel system specifically the injector. The purpose of the fuel injector is to provide the engine enough amount of fuel, if the engine does not have enough fuel it will lack power. If the fuel injector is clogged or partially clogged not enough fuel will go inside the engine and the engine will be starved of fuel.
Engine weak compression
Another cause of the engine's lack of power is when the engine is weak on compression, usually, this is because the engine valves or rings are worn out. To check if the engine has weak compression the engine must be subjected to a compression test.
What to do?
Bring the car to the repair shop depending on your initial diagnosis asks the mechanic to check the car if the problem is a clogged catalytic converter then replace it with the new one. If the problem is the spark plug or spark plug wire, replacing these parts will improve the engine performance.
If the problem is the clogged fuel injectors avoid using low octane gasoline, first is to try to fill your car with super gasoline usually 98 octanes and above because super gasoline has additives that automatically clean residue off the injectors. After filling with super gasoline a few times you will notice an improved power from the engine. If there is no improvement then that’s the time to bring the car to the repair shop and asks the mechanic to clean the injectors.
