Oshkosh Drivers: Is It Time to Replace Your PCV Valve?

The crankcase is the lower part of the engine where the crankshaft is housed and where the engine oil lives. The crankshaft is connected to the pistons that power the engine.

When you are diving around Oshkosh, fuel is burned in your vehicle engine, it pushes the pistons down and the crankshaft rotates and sends power to the transmission. Some of the explosive gases from combustion squeeze past the pistons and down into the crankcase.

Now this gas is about 70% unburned fuel. If it were allowed to remain in the crankcase, it would contaminate the oil and quickly turn it to sludge. Sludge is like Vaseline and clogs passages in the engine, leading to damage.

Also, the pressure build up would blow out seals and gaskets. So in the old days, there was just a hose that vented the crankcase out into the air. Obviously, not good for our air quality in Oshkosh, Wisconsin.

Enter the PCV valve. It's a small, one-way valve that lets out the gases from the crankcase and routes them back into the air intake system where they are re-burned in the engine. Fresh air comes into the crankcase through a breather tube. This makes for good circulation in the crankcase. And that gets the air out. As you can imagine, however, the valve gets gummed up over time.

Your vehicle manufacturer usually recommends they be changed somewhere between 20,000 to 50,000 miles/30,000 to 80,000 kilometers. Unfortunately, PCV valve replacement is left out of some vehicle owner's manuals, but your friendly service advisor at Auto Authority LLC, we will make sure your PVC is replaced if needed.

Auto Authority LLC On Your Serpentine Belt

Today we're going to be talking about serpentine belts for our Oshkosh, Wisconsin, customers. Let's start by talking about the accessories that are driven by the serpentine belt. First is the alternator. That's the device that makes electricity to power the vehicle and recharge the battery. Then there's the air conditioning compressor that makes cool air for you while you're driving around Wisconsin in the summer.

The power steering and power brake pumps are driven by the serpentine belt in most Oshkosh residents' vehicles. Those pumps provide pressure that assists your steering and braking.

In many vehicles, the water pump is driven by the serpentine belt. The water pump is what circulates the coolant that protects your engine. In some cars around Oshkosh, Wisconsin, the water pump is driven by the timing belt.

The radiator cooling fans on some vehicles are also driven by the serpentine belt. Some have separate electric motors. That's really a lot of work for one belt.

But modern engine design has a single belt that snakes around the front of the engine and drives most, if not all, of these accessories. Serpentine belts do a lot of work, but they're tough and can last for a long time.

Just how long will they last? That'll vary for each individual car in the Oshkosh area. Your owner’s manual will have a recommendation for when it should be changed, but it could need it sooner. The good news is that a visual inspection at Auto Authority LLC can detect a belt that's getting close to failing.

Your friendly and knowledgeable Auto Authority LLC service advisor can look at the belt: if it has more than three or four cracks per inch, it needs to be replaced. A deep crack that's more than half the depth of the belt - replace. Frayed, missing pieces, a shiny glazed look? Toss it. Come see us.

How to Know When to Change Your Oil at Auto Authority LLC

Today in the Auto Authority LLC auto care blog, we're going to talk to Oshkosh drivers about oil change intervals. It seems that as engine technology advances, oil change intervals become longer for Auto Authority LLC customers. For example, recently four of the world's largest vehicle manufacturer's shortened the published intervals for several of their engine models. They originally published intervals that extended out to a much as 8,000 miles (13,000 kilometers).

In real world Oshkosh driving, the oil started to sludge up before the recommended change interval. Oil sludge is a thick jelly-like substance: quite literally petroleum jelly – like Vaseline. This goop was clogging vehicle small engine passages so the oil wouldn't flow to some parts of the engine. This resulted in engine damage. We see it too often at Auto Authority LLC in Oshkosh.

The vehicle manufacturers began to offer an extended warranty to cover sludge damage. But there was a catch: the vehicle owner had to follow a new, lower service interval and provide proof of oil changes in order to make a warranty claim.

So here's the bottom line for Oshkosh vehicle owners: with longer oil change intervals, it's essential to follow them closely. Back in the day of 3 months or 3,000 miles (5,000 kilometers), if you went an extra month or an extra thousand miles or couple of thousand kilometers, your oil was still fresh enough that it didn't have time to build up much sludge.

But if your recommended interval is 6,500 miles (10,000 kilometers) and you go over another thousand miles or couple of thousands of kilometers, you're getting into heavy sludge territory. You absolutely need to follow mileage intervals very closely. And don't forget your severe service schedule. If you do a lot of stop and go driving in Wisconsin, short trips, drive in dusty or polluted Oshkosh conditions, hot or cold weather  or haul heavy loads, you're driving in severe service conditions. Your Auto Authority LLC service advisor can help you determine which schedule to follow.

So check your vehicle owner's manual or talk with your Auto Authority LLC service advisor about where and how you drive in Oshkosh. Should you change your oil closer to the regular schedule, or the severe service schedule? You need to make the call.

Let me give you an example of this. Some newer vehicles have an oil change indicator. It has a sophisticated computer algorithm that tracks number of cold starts, engine temperature, RPMs, mileage and many more variables to come up with a recommendation for when to change the oil.

Depending on driving conditions, the indicator in one test vehicle came on at anywhere from 2,500 miles (4,000 km) to almost 7,000 miles (11,000 km). It's typically just over 4,000 miles (6,500 km). Sometimes our driving is easy on the vehicle – like a long road trip. Sometimes, our driving is hard on it – like towing a heavy trailer or a lot of around town driving. But, usually, it's a combination of both.

Once again, it's up to you to make the call as to when to change your oil at Auto Authority LLC to protect your vehicle engine. Another place where Wisconsin drivers can go wrong is with the type of oil they use. More and more new cars are coming to Oshkosh owners filled with synthetic oil. Without going into a lot of detail right now, let's just say that synthetic oil lasts longer and is very resistant to oil sludge.

But it also costs quite a bit more, so some people are tempted to use conventional oil for their oil changes. Now, it's always best to use the oil recommended by your vehicle manufacturer. Check your owner's manual see if a conventional oil alternative is allowed.

But getting back to the problem, if your vehicle came from the factory with synthetic oil, the recommended oil change interval is for synthetic oil. If you use conventional oil, you can't use the synthetic interval. You need to shorten it.

Keys to Long Lasting Vehicle

New cars cost so much these days. Add financing and insurance and, well a new vehicle may not seem so attractive. A lot of Oshkosh, Wisconsin people are hoping to make their cars last a lot longer.

The good news is that with the current state of automotive engineering and manufacture, there’s no reason a modern vehicle can’t be made to last for a 150,000 miles or more.

There is an old saying that says, 'a stitch in time saves nine' and that is really true when it comes to taking care of your car. A great example is coolant service.

Over time, coolant becomes corrosive and actually starts to damage your radiator and other parts. That’s why you need to have your cooling system serviced on a regular schedule.

The same is true for your power steering system, brake fluid, air conditioning system, differential and transmission. And your oil changes should be done right on schedule to avoid the build up of harmful oil sludge.

Don't let your brake pads go too long before they are worn to the point that they cause damage to rotors. Preventive maintenance is a great way to keep your operating costs down.

Replacing belts and hoses is much cheaper than repairing the damage that can be caused by failure.

Now this is a lot to remember. The Auto Authority LLC can keep on top of this stuff. We can tell you what your manufacturer recommends and help you with a plan to take care of it.

Bottom line – take care of this stuff on schedule and you will reduce operating costs, prevent costly damage and maintain your warranty coverage. Call The Auto Authority LLC today for an appointment; you can reach us at 920-231-1016.

Take good care of your car, and it’ll take good care of you.
