TCB your PCV (PCV Valve Replacement)

Your gasoline engine goes through some exhausting work.  Yes, it's truly exhausting, as in: it produces exhaust! And when your engine starts behaving like it's exhausted, such as running poorly or getting lousy fuel economy, the trouble may be something called a PCV valve.

Did you know it's a series of explosions that creates the power in your engine? The spark plugs ignite a mixture of gasoline and air and BANG! A whole bunch of those and you're engine is humming away. Leftover vapors from those explosions go into your crankcase, which is also a place where engine oil goes.  Those vapors still have a lot of unburned fuel in them, and if they had nowhere to go, they'd turn your oil into a thick mess called sludge, not good for a smooth running engine. 

Engineers came up with an idea. Re-direct those gasses building up in the crankcase into the engine's air intake and mix them with fresh air.  That way the unburned fuel could go through the engine again and produce power. It also means the unburned fuel doesn't pollute the air.  The part that makes that happen is called the Positive Crankcase Ventilation (PCV) valve.

Besides reducing pollution and preventing the oil from turning to sludge, the PCV valve also relieves pressure in the crankcase, reducing the potential for oil to leak. One of the reasons you should get your oil changed as frequently as your vehicle's manufacturer recommends is that it helps reduce chances for problems with the PCV valve.

After a while, the PCV valve can itself get gummed up and stick, and the driver may notice oil leaks, reduced power or engine hesitation.  That's why it's important to make sure the PCV valve is operating like it should, and often it can be diagnosed during a visual inspection by our technicians.  Replacing a PCV valve is usually quick and inexpensive.  After it's done, your vehicle will run with the performance and fuel economy you're used to.  Goodbye exhaustion!

The Best Book that's Not a Best-Seller

Sometimes the movie is better than the book, sometimes it's the other way around.  But when it comes to your vehicle, the best book of all is the owner's manual. The plot is simple: Owner wants long life and dependable performance from the vehicle, manual has the way to achieve that long life and dependable performance.

And yet, it's amazing that some people will own a vehicle for years and never even crack this book.  They'll only read it when they absolutely have to, for things like finding out how to change the clock. 

Ok, so you're probably not going to rush right over to your glove box and start reading the owner's manual cover to cover.  We know that.  But just think of what you can get out of it.

Consider this.  Those who wrote or helped write this book include the engineers who designed it and the people who tested and refined it.  They know more about your vehicle than anyone, period.  They know how long a part is likely to last and what you need to do to take care of it. They know how far a distance or how long a time you can drive before you have to change certain fluids in it.  They know what temperature it can reach before things will start to break.

And they've put your vehicle model through torture, testing it in the absolute worst conditions to see how to make it stand up to more abuse than it will ever receive.  They've then torn it down, examined it and, in many cases, redesigned the parts to make them even better. 

And they've put down—in fairly minute detail—this blueprint that, if you and our experts at Muffler & Go follow their suggestions, will make it very likely that your vehicle will serve you well for a long time.  If you don't follow those suggestions, all bets are off.

We didn't even mention that the owner's manual tells you how to operate everything in your car.  How to adjust the heat and air conditioning, how to pair your smartphone with the audio system, how to program your key fob so it won't sound the horn when you lock your vehicle.

Have you lost your manual or did you buy a vehicle that didn't come with one?  Many are available either online or in paper form. If you don't know where to begin with such a long book, try a couple of pages a week, just three minutes.  You’ll discover your vehicle does things you never even knew it could do.  And the movie will never be as good.

What is a TSB? (Technical Service Bulletins)

If your vehicle had something in its design or production that the manufacturer had figured out had an unanticipated problem, you'd want to know about it. And you'd want it fixed. There is something that can help drivers with just such a scenario. It's called a Technical Service Bulletin, or TSB.

Here's what a TSB is. Vehicle design and manufacturing is a very complex process. Aftrer every vehicle is introduced, the more units there are on the road, the more likely weaknesses in parts or design will start to show up.

Automakers gather data on the issues and how best to fix them. Then they send out TSBs (usually in the first year of the new model) so technicians will know to look for those problems and what to do about them. There may be more than one cause of a problem with a vehicle so there may be more than one TSB for an issue.

A TSB can be issued for anything from failing water pumps to strange noises to smelly headliners. A TSB and a recall aren't the same thing. A recall is issued if there's a problem that could cause harm to people or if it creates illegal emissions. The manufacturer pays for a safety defect to be fixed, and the repair is usually performed at a dealership.

But when a Technical Service Bulletin is issued, it's because there's a pattern of some system not working the way it should. If a vehicle is under warranty and the problem can be diagnosed in a specific vehicle, the manufacturer will probably pay for the repair. But there may be limits. Take one case with certain models of a minivan. Some wheel bearings were failing prematurely, so the manufacturer extended the warranty on them to 5 years or 90,000 miles/145,000 km. After that, the owner bore the cost. In some cases, a manufacturer will reimburse owners for a repair already done at an independent service facility.

You may have a vehicle that is no longer covered by a warranty but a TSB has been issued for a certain problem. In that case, any service facility can perform the service. At Muffler & Go, your service advisor will have access to TSBs that have been issued for your vehicle's year and model. They will help the technician diagnose it if your vehicle has the issue. The TSB will also have advice for the best repair procedure to get your vehicle working the way it should.
