Positive Crankcase Ventilation – PCV Valve Service at Meadowvale Auto Repair Specialists Ltd.

Posted June 12, 2017 12:05 PM

Hello Mississauga! Did you know that the first federally-mandated emissions control device was introduced in the 1960's? The Positive Crankcase Ventilation valve, or PCV valve, has been installed in Ontario vehicles since 1964 and represents the first legislation by the United States government to regulate harmful emissions as well as to improve performance in the country's vehicles.

The PCV valve, as you can probably guess, is located on the crankcase. The crankcase is the lowest part of a vehicle's engine. It houses the crankshaft and the engine oil. The crankshaft connects to the pistons that power the engine.

Pistons are pushed down when fuel is burned in an engine. This causes the crankshaft to rotate, which sends power to the transmission.  It ultimately turns the axles and causes the vehicle to move. Some of the gases released by the burning fuel squeeze around the pistons and down into the crankcase.

If the escaped gases mix with the engine oil in the crankcase, oil sludge develops. This sludge has the consistency of petroleum jelly and can cause damage by clogging up passageways in the engine. Further, escaped gases can build up pressure inside the crankcase that can blow out seals and gaskets.

Before 1964, a hose was attached to the crankcase that vented escaped gases out into the air. These gases contained about 70% unburned fuel as well as harmful emissions. The PCV valve was designed to curb these harmful emissions as well as recapture unburned fuel.

The PCV valve is a small, one-way valve that allows escaped gases to exit the crankcase. The gases are then routed into the intake system so they can be re-burned in the engine. Fresh air enters the crankcase through a breather tube to facilitate this circulation and keep the air in the crankcase clean.

The PCV valve, like most working parts on a vehicle, will wear out over time. Usually it simply gets gummed up. Preventive maintenance, including routine oil changes at Meadowvale Auto Repair Specialists Ltd. in Mississauga, will extend the life of the valve, but eventually it will have to be replaced. A sticking PCV valve won't allow gases to circulate properly, which can increase pressure in the crankcase. Over time, that pressure will lead to oil leaks.

Your vehicle manufacturer recommends that a PCV valve be replaced every 20,000 to 50,000 miles (32,000 to 80,000 kilometers), depending on the vehicle and Mississauga driving conditions. It's an inexpensive repair but may not be included in the maintenance schedule in your owner's manual.  So if you're looking for auto advice about the PCV valve, you may have to ask our pros at Meadowvale Auto Repair Specialists Ltd..

Taking care of our PCV valve protects the environment in Ontario and improves vehicle performance. It's just part of good vehicle care for Mississauga drivers and a way all of us can do our part to improve the world we live in.

PCV Valve: What Is It?

Posted December 13, 2016 12:44 PM

Most Mississauga drivers know something about preventive maintenance on a vehicle. We know we should routinely replace the oil and wiper blades and other fluids. But have you heard of a PCV valve ? This little car part needs to be replaced regularly or it can cause some serious problems in your vehicle engine.

PCV stands for Positive Crankcase Ventilation. The crankcase holds your motor oil and is located at the bottom of your engine.

When fuel is burned in your engine, it produces waste gases that are mostly vented out through your exhaust system. But some of these gases push their way past the pistons and into the crankcase. There, these gases can mix with motor oil to produce oil sludge, which can damage vehicle engine parts through corrosion and by clogging engine passages. Mississauga vehicle owners should be advised that if the engine is running at high speeds, these gases can also cause pressure inside the crankcase to build up. This pressure, in turn, can blow gaskets and damage seals, leading to oil leaks.

The waste gases that leave the engine are comprised of about 70% unburned fuel. They used to be vented off the crankcase into the atmosphere. But starting in 1964, laws mandated that these gases be recaptured. Manufacturers began installing PCV systems, which recycled the gases into the air intake system where they could be mixed with fuel and sent to the engine to be burned.

The PCV valve is a one-way valve attached to the crankcase. Waste gases exit the crankcase through the valve but cannot enter.

Over time, the waste gases leave deposits on the PCV valve that can gum it up. So it needs to be replaced occasionally. This is an inexpensive part of preventive maintenance that is often overlooked, but which can have very expensive consequences. It's good auto advice to keep this little valve clean and working well.

In order to maintain efficient circulation, the PCV system also has a breather tube that allows clean air to enter the crankcase. This air is usually filtered through the engine air filter. But some vehicles have a separate air filter for the breather tube called the breather element. If this is the case with your vehicle, proper maintenance of the PCV will include replacing this element. To find out whether your vehicle has this type of PCV system, check your owner's manual or ask your service advisor at Meadowvale Auto Repair Specialists Ltd..

The PCV system reduces harmful vehicle emissions. The maintenance it requires is simple and inexpensive at Meadowvale Auto Repair Specialists Ltd.. A fouled or damaged PCV system can lead to serious engine damage for Mississauga drivers.

Let's all learn to practice good car care. It's good for our wallets, and it's good for our Ontario environment.

Exhaust Service at Meadowvale Auto Repair Specialists Ltd.: Passing the Smell Test

Posted May 23, 2016 7:22 AM

The exhaust system on a vehicle is more complex than most Mississauga residents realize. It contains everything from old-fashioned pipes and clamps to sophisticated computers and sensors. All Ontario folks know a properly functioning exhaust system is good for the environment, but sometimes we forget that a damaged exhaust system can be deadly. That's why preventive maintenance on your exhaust system is so important. We can help you with that at Meadowvale Auto Repair Specialists Ltd. in Mississauga.

The exhaust manifold is the first component in your exhaust system. The manifold is attached to the engine. It collects the gases that are produced by the engine and directs them into the exhaust pipes. At this point, these gases are both hot and chemically dangerous.

One of the gases produced in your engine is carbon monoxide. This gas is colorless and odorless. Breathing it can cause headaches, dizziness, nausea and drowsiness. Continue breathing it and you will die.

To keep this gas and others from entering your vehicle passenger compartment, the connections from the manifold to the engine and from the manifold to the exhaust pipes are sealed with gaskets. These connections should be routinely inspected at Meadowvale Auto Repair Specialists Ltd. for cracks and to check if they have come loose.

The exhaust pipes can also get damaged, allowing dangerous gases to leak into your passenger compartment. These pipes can rust or be dented or broken by rocks and other roadway debris, so they need to be inspected regularly.

The catalytic converter is the next component in your vehicle exhaust system. You can breathe a sigh of relief now, because this is where the dangerous engine gases are converted into carbon dioxide and water, greatly reducing the amount of harmful emissions in your exhaust. You'll also be happy to know that your catalytic converter doesn't require maintenance. However, it will wear out. If you fail an emissions inspection because of a faulty catalytic converter, you need to replace it.

The muffler's job is far less critical, but far more noticeable, than the catalytic converter's. It dampens or absorbs the noise from the engine. Most Mississauga residents don't realize that we can actually customize the noise our car makes with a custom muffler. You can upgrade to a muffler that will make your car sleuth-quiet, or you can advertise your presence in Mississauga with a sassy rumble.

Mufflers can also rust or be damaged by road debris. But just because their main function is to dampen out engine noise doesn't mean they can be ignored. If your muffler is leaking, you need to get it replaced quickly. Exhaust fumes need to exit through your tailpipe, not your muffler.

The exhaust pipe contains at least one oxygen sensor. The sensor monitors the oxygen content of the exhaust, which allows it to adjust the fuel-to-air ratio in the engine. This keeps your vehicle engine running smoothly and maintains good fuel economy. So, besides keeping you and the environment healthy, a well-maintained exhaust system also keeps your vehicle healthy. The tailpipe itself can rust or get damaged by road debris, so it needs a quick inspection once in a while, too.

The whole exhaust system is mounted on the vehicle with clamps and hangers. These clamps and hangers can come loose, rust or get dinged up by road debris. Remember that the gases in your exhaust system are hot, so the exhaust system itself gets hot. The clamps and hangers keep the exhaust system attached to the vehicle, but they also prevent the heated components from touching things they shouldn't. If you don't inspect and replace broken, loose or damaged clamps, you may end up with melted wires, hoses or lines. And that can spell some expensive repairs.

You should schedule an exhaust system inspection as recommended in your vehicle owner's manual. Because this system is critical to your health and the health of your car, and because of its sophistication and complexity, you need to have the work done at a qualified service center such as Meadowvale Auto Repair Specialists Ltd. in Mississauga.

Maintaining your emissions and exhaust system is not just good auto advice: it's good health advice for all Mississauga residents and their families.

Meadowvale Auto Repair Specialists Ltd. Service for Your Exhaust System

Posted August 26, 2015 12:00 PM

Your vehicle's exhaust system is more than just a tailpipe and a muffler. In fact, it is one of the most complex systems on your vehicle.

The manifold is attached to the vehicle engine. It collects exhaust from the cylinders and directs it into the exhaust pipe. Gaskets seal the connection of the manifold to the engine and to other joints. A cracked or loose manifold or a leaking or damaged gasket can allow dangerous gases to enter the passenger compartment of a vehicle. One of these gases is carbon monoxide, which is colorless, odorless and deadly. For this reason, it is important Mississauga residents keep their exhaust system in good repair.


The pipes that connect the various parts of the exhaust system can rust or be damaged by rocks or other road debris. Such damage can cause dangerous gases to leak into the air.

The catalytic converter is the next component of your vehicle exhaust system. It sort of looks like a muffler. Its job is to change dangerous gases into harmless carbon dioxide and water. The catalytic converter doesn't require any regular maintenance, but it can wear out. If it fails, you will need a new catalytic converter to pass an emissions test in Ontario. Call Meadowvale Auto Repair Specialists Ltd. at 905-821-4992 if you suspect a problem with your catalytic converter.

Oxygen sensors in the exhaust pipe monitor the oxygen content of the exhaust. This helps the vehicle engine's computer keep the fuel-to-air mixture at optimal levels.

The muffler is also part of your vehicle exhaust system, but it deals with a different kind of emission. It keeps your vehicle from emitting bad sounds. Mufflers act like finely tuned musical instruments. They create a feedback of sound waves to absorb or decrease the noises made by your engine. Different mufflers can create different sound waves, so you can actually “tune” your car to produce a particular sound, anything from whisper to rumble.

It is important that damaged mufflers be replaced immediately at your Mississauga automotive service center, especially if they are leaking. Not only will the extra noise annoy your Mississauga neighbors, a leaky muffler could be serious.

The entire exhaust system is attached to your vehicle by hangers and clamps. These fasteners can rust, come loose or break. The components of the exhaust system can get very hot, so when the hangers or clamps fail, these hot components can come into contact with other parts such as wires and hoses. These can melt, causing serious and damage to your vehicle. Good car care requires that you have your exhaust system inspected regularly.

Caring for your vehicle exhaust system at Meadowvale Auto Repair Specialists Ltd. yields cosmetic benefits like quieting your engine sounds, but also may impact your health and safety. Your life, or the life of a loved one, may actually be on the line.

Mississauga Exhaust and Emissions Service

Posted May 8, 2013 12:00 PM

Many Mississauga residents don't realize that there is more to exhaust system maintenance than just tailpipes and mufflers, if you can see smoke or if it's too loud. Exhaust service at a full-service automotive center like Meadowvale Auto Repair Specialists Ltd. is really a lot more comprehensive these days.

For example, in the U.S., the federal government required catalytic converters for all cars in 1976 and on-board emission control computers in 1990. Ontario and federal emissions requirements have forced manufacturers to come up with much more sophisticated ways to comply with environmental laws. This also goes for cars sold in Canada.

So, exhaust service has really become exhaust and emissions service. High-tech computer-controlled emissions devices are now necessary. And because it's so sophisticated, we recommend having your emission system checked out by a qualified technician, like the ones we have at Meadowvale Auto Repair Specialists Ltd., regularly to make sure everything's working right – which is usually every six months or 6,000 miles/10,000 kilometers.

If your 'check engine light' comes on while you are driving around the Mississauga area, especially if it's flashing, then you need to bring your car into Meadowvale Auto Repair Specialists Ltd. ASAP. Chances are it's an emission related problem. Signs of exhaust or emissions trouble include difficulty starting, engine noise or smoke.

We hope this hasn't been too 'exhausting' of a discussion. Remember that a properly functioning exhaust system is for Ontario’s health and safety. Talk with your friendly and knowledgeable service advisor at Meadowvale Auto Repair Specialists Ltd. in Mississauga if you think you might need your exhaust system checked. A quick look can sure save a lot of pain down the road.

Whenever they hear the term "exhaust service," most Mississauga residents think about exhaust pipes and mufflers. Well, actually, exhaust service at Meadowvale Auto Repair Specialists Ltd. is a lot more comprehensive these days. For example, catalytic converters were mandated in 1976 and on-board emission control computers in 1990. Governmental emissions requirements have forced manufacturers to come up with much more sophisticated ways to comply with environmental regulations.

Exhaust service has really become exhaust and emissions service. High-tech computer controlled emissions devices are now a big part of exhaust service. Because it is so sophisticated, your recommends you have your emission system checked out by a qualified Mississauga exhaust technician regularly to make sure everything is working right - usually every 6 months or 10,000 miles/16,000 kilometers.

If your Check Engine light comes on, especially if it's flashing, get your car looked at right away. Technicians at Meadowvale Auto Repair Specialists Ltd. in Mississauga handle emission problems everyday. You might have exhaust or emissions trouble if your car is difficult to start, runs rough, is noisy or smoking. Call Meadowvale Auto Repair Specialists Ltd. at 905-821-4992 to schedule an appointment if you experience these problems.


Let's review the exhaust system. We will start from the top with the exhaust manifold. That is the part that attaches to the engine and collects the exhaust from the cylinders and directs it into the exhaust pipe. Exhaust gaskets help seal the connection with the manifold and various other joints along the way. If the manifold is cracked or loose or a gasket is leaking, gases could escape into the passenger compartment where you ride. Carbon monoxide can be deadly, so it is important that your exhaust system doesn't leak. The exhaust pipes connect the various components. They can rust or be damaged by a rock, so they need to be inspected periodically.

Next is the catalytic converter. This part looks like a muffler. It changes chemicals that are dangerous to your health and our Mississauga environment into harmless carbon dioxide and water. It doesn't require any maintenance itself. But eventually they wear out. Mississauga drivers find this out when their car fails an emissions inspection.

Now the muffler. Its main job is to quiet engine noises. Mufflers work by either absorbing or baffling sound. And you can actually customize your car's sound with different mufflers - anything from whisper quiet to bad-boy rumbley. Rusted or road-damaged mufflers can leak and need to be replaced right away. Talk to your friendly and knowledgeable service advisor at Meadowvale Auto Repair Specialists Ltd. .

The exhaust system is attached to the vehicle by a series of hangers and clamps. These fasteners hold the system in place. When hangers come loose or break, hot exhaust components can touch and melt wires, hoses and lines.

Finally, we end at the tailpipe. This is the final outlet for the exhaust. These can be plain-Jane or pretty flashy. Also, the oxygen sensors monitor the oxygen content of the exhaust so the engine control computer can adjust the fuel-to-air mix to keep the car running right.

Exhaust and emissions service at Meadowvale Auto Repair Specialists Ltd. in Mississauga covers plain old pipes and high-tech computers. It impacts everything from life-and-death safety due to exhaust leaks to fine-tuning the sound of your ride.
