PCV Valve Replacement

Pro Muffler PCV Valve Testing
Pro Muffler & Brake Shop Inc Tech Question:
What is a PCV Valve and should I test it?

Pro Muffler & Brake Shop Inc Tech Answer:

The PCV valve is a little, inexpensive part that does a big job for Benton Harbor and our environment here in Michigan. PCV stands for Positive Crankcase Ventilation. The crankcase is the bottom area of the engine that holds the oil. When the engine’s running, fuel is burned to generate power. Most of the exhaust from combustion goes out through the exhaust system. But some exhaust blows by the pistons and goes into the lower engine, or crankcase.

These hot gases are about seventy percent unburned fuel. This can dilute and contaminate the oil, leading to damaging engine oil sludge. It can also cause engine corrosion. At high speeds, the pressure can build up to the point that gaskets and seals start to leak. Over time, the vented gases will gum up the PCV valve and it won’t work well. That can lead to all of the problems I’ve already described, oil leaks, excessive oil consumption and reduced .

Fortunately, it’s very easy to test the PCV valve and quick and inexpensive to replace at Pro Muffler & Brake in Benton Harbor. Even so, it’s often overlooked because many people in Benton Harbor don’t know about it. Check your owner’s manual or ask our friendly and knowledgeable technicians at Pro Muffler & Brake. If this is the first time you’ve heard of a PCV valve, you might be in line for a replacement.

Please ask us at Pro Muffler & Brake about your PCV valve. For the price of a couple of burger combo meals at your favorite Benton Harbor drive-up window, you can avoid some very expensive deep engine repairs.

Exhaust Systems

exhaust_system_01

We’ve all heard a car or truck in our Benton Harbor neighborhoods that needs a new muffler. But there’s more to the exhaust system than just the muffler.

The exhaust system has three main functions:

  • To safely get hot exhaust gas from the engine out the tailpipe
  • Treats the exhaust to remove harmful pollutants
  • Muffle the engine noise

Exhaust gas is poisonous. You don’t want it getting into the passenger compartment. For example, carbon monoxide can be deadly. That’s why you should never run your engine in a closed garage. If you have a leak in the exhaust system, exhaust could get into the passenger cabin and make you sick or even kill you.

If you smell exhaust in the vehicle, roll down your windows and get it inspected. You may smell or see exhaust coming from the engine compartment or under the vehicle if you have a leak. Sometimes the sound from an exhaust leak is loud and obvious. Sometimes it’s a ticking sound when you start the engine that goes away as you drive. That could be a small crack or a bad fitting that leaks when it’s cold but seals up when the metal heats and expands.

Now, let’s address the environmental issues for our Benton Harbor community. Exhaust gas contains a number of pollutants and particulates. The catalytic converter scrubs some of those harmful substances. And diesel vehicles have systems to deal with soot.

Catalytic converters eventually wear out and need to be replaced. They’re expensive so you want to help them last as long as possible by keeping the fuel system clean and replacing your air filter. These components need to be tested for function with an emissions test from time to time.

And that leaves the muffler. The beauty of getting a new muffler is that you can suit your taste: Some want whisper quiet and others like a little rumble. And some like a roar when they drive down our Benton Harbor streets.

Exhaust Service – Failed Emissions Test

Pro Muffler & Brake Shop Tech Question:
My car failed its emissions test – what do I need to do?

Pro Muffler & Brake Shop Answer:
Let’s get this out of the way: a leak in your exhaust system could be deadly. If Benton Harbor motorists smell exhaust in the passenger cabin or hear an unusual exhaust sound, they should get their exhaust system checked and repaired. Talk to your friendly & knowledgeable Pro Muffler & Brake Shop service advisor This is vital: Carbon monoxide in your exhaust is odorless, colorless and tasteless can be fatal to you and your passengers so don’t delay if you suspect and exhaust leak.

There could be a number of reasons for a failed Michigan emissions test so some vital diagnostic work is in order. A common reason for Benton Harbor auto owners is that the catalytic converter has failed. The catalytic converter removes some of the harmful elements in exhaust.

When a catalytic converter fails it must be replaced, which isn’t cheap for Benton Harbor auto owners. Many Benton Harbor folks stop there – but the converter failed for a reason. There may be any number of engine run conditions that led to the failure. It would certainly be smart to have your friendly & knowledgeable Pro Muffler & Brake Shop technician diagnose the cause so that you don’t end up with another pricey catalytic converter replacement down the road.

Oh, and that Check Engine Light that so many Benton Harbor motorists ignore: It might just be illuminated for a an important condition that could lead to catalytic converter damage. Have your Pro Muffler & Brake Shop technician get to the bottom of any check engine light situation.

Exhaust System Construction & Function

Exhaust System Construction & Function

Your exhaust system begins at the engine with the purpose of removing toxic gases and fumes from your vehicle. The components are a series of pipes, catalytic converters, sensors, mufflers, and often a resonator, as well as other emission devises. The exhaust system is exceptionally “hot” when the engine is running. Please use caution when close to exhaust components.

Beginning at the engine, hot toxic exhaust gases travel through an exhaust manifold, primary exhaust pipe and into a “catalytic converter”. Immediately following the converter is another exhaust pipe that extends to a muffler, then to a resonator or tail pipe. The gases safely exit the rear of the vehicle. Your vehicles muffler reduces the noise your engine makes when it is running. The resonator is another type of muffler that further reduces the noise your car makes. Additionally, condensation is a product of combustion in the engine so you may see water dripping from the tailpipe from time to time.

If you have concerns about your exhaust system we are happy to provide you with a FREE Exhaust Inspection to determine if anything is wrong with your vehicle. If so, we will show you the problem, explain what needs to be done and give you a no obligation estimate. Most importantly, we promise that your bill will match your estimate to the penny.
