There are several things that might happen if a significant amount of excess oil is added to your engine.

Changes in the oil pressure and overall lubrication of the engine can lead to:

  • Engine damage such as bent rods in the engine or collapsed valve pipes
  • Catastrophic engine failure where the engine sustains enough damage that it cannot be repaired, but must instead be replaced
  • Excess engine wear from inconsistent oil pressure over time
  • Spark plug fouling, resulting in the need to replace spark plugs more frequently
  • Excess oil deposits in the catalytic converter

Automotive oil reservoirs are designed to hold a bit of extra oil to compensate for fluid expansion in warm conditions, and to help prevent damage to the engine in case excessive oil is added to the engine. As a result, half a quart may not cause any damage to your engine, but much more than that could lead to engine damage.

When too much oil is poured into the reservoir, the excess oil can be pulled into the crankshaft as it spins. The oil is mixed with air and aerates – also known as ‘foaming’ – like what you might find on your morning latte. The combination of oil and air results in decreased oil pressure as the oil pump is unable to continue pumping the oil effectively.

Overfilling the oil can cause the car to have misfires and run rough. It will also blow a lot of smoke out of the tail pipe. This usually will not cause any long lasting damage.

If you are worried that you have overfilled your vehicles oil just bring it into any of our Sierra Car Care and Tire Center locations and our mechanics can let you know what they recommend.

Built with durability, reliability, and optimization in mind, diesel engine systems are designed to use their own compression to ignite fuel.

In gasoline engines, the fuel is mixed with air, compressed by pistons, and ignited by a spark plug.

The rate of compression in a diesel engine is more than three times that of a regular gasoline engine system. In a diesel engine system, the air is compressed at a high compression ratio, which introduces a great amount of heat. Following this compression, fuel is directly injected into the cylinder, where the fuel vapor is ignited.

Diesel engines are built without spark plugs. Instead, diesel systems use glow plugs to start and run more efficiently in colder temperatures. Glow plugs have two heating elements that allow them to get very hot very quickly for fast starts. Turbochargers increase the compression ignition by quickly compressing the air flowing into the engine, allowing for more air to flow into the chamber. More air in the combustion chamber means more fuel can be added to the combustion process. Turbochargers provide diesel engine systems with improved efficiency, and ultimately, more miles per gallon of diesel fuel.

Importance of Diesel Engine Repair

Your diesel engine plays a major role in your vehicle, so it is especially important that you be aware of problems and seek repairs whenever you experience an issue. Because diesel engines make a considerable amount of noise during normal, everyday operation, diagnosing diesel engine problems can be hard to do if you are listening solely to the engine. However, there are a number of symptoms you can watch out for that indicate your diesel engine needs maintenance.

A diesel engine running at lower RPMs or a hard-to-start engine are signs of low fuel pressure, but these signs may also be symptoms of an insufficient fuel supply or poor fuel quality. Allowing our staff to troubleshoot your diesel engine can help ensure that the proper repair procedures are followed to repair the engine.

Every diesel engine manufacturer requires different preventive maintenance procedures, so referring to your owner’s manual will help in planning and scheduling routine maintenance services. Keeping all diesel engine components—glow plugs, fuel injectors, and turbochargers—in proper working order will increase the life of your diesel engine system while promoting overall vehicle maintenance.

The “check engine” or “service engine” light is a sure sign that your engine should be looked at by an expert sooner rather than later.

Most of the time, your vehicle’s On-Board Diagnostics System will detect an engine issue and store the corresponding repair code, which can be accessed by a member of our service staff. Slow-cranking, rough idling, stalling, knocking, or pinging while accelerating are all signs that you should seek engine repairs or engine diagnostics to determine the full extent of your engine trouble.

A decrease in gas mileage and detectable loss of power during acceleration are also signs of an impending engine tune-up or engine repair service. Engine warning lights help alert drivers to minor issues before they become major repairs.

Be sure to follow up with our staff once your vehicle’s On-Board Diagnostics System detects a problem with your engine.

Description of Engine Diagnostics and Performance

Discrepancies in performance levels are reported through your vehicle’s computer system. Once the “check engine” or “service engine” light is displayed, your next step should be to seek out an engine diagnostic service or an engine tune-up.

Engine diagnostics allow our staff to gather helpful information about the operating condition of your engine. The insights obtained during an engine diagnostic will determine the extent of suggested engine repairs. The most common diagnostic trouble codes are generated in response to malfunctions in the power-train.

Ultimately, regular engine tune-ups are necessary to optimize engine performance. A tune-up is also one of the most effective ways to prevent unexpected engine trouble.

During an engine tune-up, our staff may replace the spark plugs, spark plug wires, air filter, fuel filter, and distributor cap and rotor in your vehicle. Our experts will also check emission levels, fuel lines, and belts and hoses. Engine diagnostics and regular engine tune-ups can help extend the life of your vehicle and improve the health of your engine.

Oxygen (O2) sensors play a vital role in maintaining peak engine performance. If you think your oxygen sensor is malfunctioning, there are a few factors to consider. Continuing to drive while your O2 sensor is not performing correctly can cause a 15% decrease in mileage. That can really add to your cost at the gas pump!

Earth Day 2015

What is the function of the O2 Sensor?
The O2 sensor is mounted in the exhaust manifold to monitor how much unburned oxygen is in the exhaust, as the exhaust exits the engine. Monitoring oxygen levels in the exhaust is a way of gauging the fuel mixture. It tells the computer if the fuel mixture is burning rich (less oxygen) or lean (more oxygen).

How long does an O2 Sensor typically last?
An oxygen sensor can last anywhere from 30,000 to 100,000 miles depending on type and vehicle. When the O2 Sensor malfunctions your “Service Engine Soon” light will come on and a diagnostic trouble code(s) will be stored.

There may be multiple codes stored for a sensor. A fuel delivery malfunction can be the reason for an oxygen sensor to fail. A fuel injector malfunction could be the root cause for the sensor failure. Just replacing the sensor may not be a long-term solution.

Sierra Car Care and MST Tire Center can help!
Bring your vehicle by any of our 4 Full Service vehicle repair and tire stations around the Reno area. One of our technicians can check your engine codes to see if there are any issues and provide solutions to get you back on the road quick.

Don’t try smog your vehicle with a malfunctioning O2 Sensor
A malfunctioning O2 sensor will not pass a smog test.

Also, if your vehicle runs from a main computer and you have just replaced your O2 sensor, your computer codes have been reset. This means that now you need to drive 50 – 75 miles without turning your vehicle off, before your computer will log any new data. After the new data has been logged, then you should proceed with a smog check.

If you go to a smog check station, typically you will be charged a fee (sometimes smaller fee than a regular smog check fee) even if your vehicle does not pass the smog test.

So, save yourself the hassle and get your vehicle looked at if you suspect your O2 sensor is not functioning properly. Visit SierraCarCare.com for locations and more information.

As the mornings have grown colder, I’ve noticed my heater isn’t putting out hot air. With winter approaching, I’d like to get this fixed soon.

Cold-Mornings-Car

The method used to warm a car’s cabin isn’t very different from the one used to keep the engine cool. In fact, it’s all hooked together and runs on the same circuit. Coolant circulates through the engine and absorbs engine heat, which is exchanged with the outside air by way of the radiator. A much smaller radiator called the heater core uses the same hot coolant to keep the cabin toasty. In general, there are two things that can go wrong with this setup.

Here are the two main culprits of reduced heat output in your vehicle’s cabin:

1) The first item to check is the engine temperature. To help cold engines warm up fast, the flow of coolant is restricted by way of the thermostat—a thermal valve that opens when it’s hot and closes when it’s cold. When the thermostat wears out, it remains stuck open or shut, which leads to either overheating or cool operation.

A worn-out thermostat might be preventing the coolant from getting warm enough to heat the cabin. Replacing the thermostat can be a 20-minute job or a real hassle. Check your service manual to see how involved the replacement is or stop by any of our 5 convenient locations in the Reno-Sparks area.

2) If the thermostat is fine, the flow of coolant in the heater core may be restricted by built-up goop. Sediment and grime can accumulate between coolant changes and collect in the heater core.

A flush can be done by disconnecting the heater hoses at the water pump (when the car is cold) and using compressed air to push the coolant and gunk backward, out the inlet hose. Be sure to capture all the old coolant and dispose of it properly. Follow that with a few rounds of filling the core with tap water and flushing it out in the same way, then refill the core with mixed coolant and reattach the hoses. None of these fixes are hard, but the heater-core flush is messy, so you might want to take your car to a shop for service.

Properly maintaining the cooling system is key for the heating system of your vehicle to work efficiently. Having the coolant in your engine flushed regularly and re-filled with the clean coolant/water mix is very important along with repairing any leaks that occur in your cooling system. We recommend having your cooling/heating system inspected on a regular basis with each oil change, so that you are aware of any issues and can have them repaired while they are still small.

flat-tireLet’s take a look at some of the most common roadside emergencies drivers may face.

So, You Have a Flat Tire…
Are you prepared for this? Maybe you ran over a nail at a friends house, or a jagged rock on a dirt road… flat tires happen. But the important thing to think about is: Are you prepared for a flat tire, should it happen to you?

We are in the heaviest part of the travel season and good tires matter, especially with climbing temperatures across the U.S. The last thing you need is less than satisfactory tires when you may or may not have family members with you.

  • Always check tire pressure before any extended driving trips.
  • Make sure you have sufficient tire tread for the trip on or off-road. Try the penny test to measure tire tread. This is especially important for RVs, Campers and Tow Trailers. Search our online tire warehouse for all your tire needs: MST Tire Center | Tire Warehouse

Quick Solutions For a Flat Tire
Important items you will need to repair your flat tire:

  • Spare Tire / Donut
  • Jack
  • Lug Nut Bar

If you are missing any of these items, you had better call a tow truck. (It is recommended to check your spare tire each month and keep it properly inflated as well, so it’s ready to go when you need it most.)

If you have a nail stuck in your tire, leave it in, until you are somewhere you can either get a tire plug kit (temporary fix) or get your vehicle to a tire repair shop.

Is Your Vehicle Leaking Antifreeze?
Did you get ready to leave only to find a puddle of green below you vehicle? You may have a leak in your radiator. This can cause over-heating, reduced engine performance, and ultimately engine failure if not properly taken care of.

Cars are not supposed to leak antifreeze, also known as engine coolant. The fluid runs from different parts of the engine to others and is always contained. If you see this greenish fluid on the ground or other engine parts, something is broken or split and must be repaired or replaced.

If you are not a trained mechanic even the quick-search remedies online may not help, you may want to see a car care professional, preferably an ASE Certified Technician

Smoke Coming From Under the Hood? This could be caused by a few different things, oil on your engine, accidently leaving the oil cap off and driving, blown head gasket, over-heating radiator, etc. Maybe you took your vehicle to one of those “Express” oil change service stations, and they got oil all over your engine?

There are a number of reasons this may happen, but if you car doesn’t start after cooling and maybe adding some water to the radiator… you may want to get your vehicle towed to the nearest service station.

Did You Turn the Key in the Ignition Only to Find that Nothing Works and Your Engine Won’t Start?

If you are having trouble starting your engine, visit us for a battery replacement service. We will determine if the battery is the cause of the problem and in need of replacement.

If your battery has low voltage, it may just be time for a replacement. On average, a battery will last 3-5 years, but driving habits and exposure to extreme elements can shorten the life of your car battery.

If your battery is good, then you may need an inspection on your engine starter and/or electrical system.

These are just a few of the most common roadside emergencies drivers face on the road. If you find yourself in need of an expert opinion for you vehicle, just come on by and we’ll take care of you.
