PCV Valve Replacement

Hello Thousand Oaks, let's talk about your often-unnoticed but extremely important PCV valve. The energy from exploding fuel is what powers your engine. But some of the vapors from the explosions escape into the lower part of the engine, called the crankcase. The crankcase is where your engine oil hangs out. These gases are about 70% unburned fuel. If the gases were allowed to stay in the crankcase, they would quickly contaminate the oil and turn it to sludge. Thousand Oaks folks know that sludge is one of the biggest enemies of your engine, clogging it up and eventually leading to expensive failures. Also, the pressure buildup would cause seals and gaskets to blow out. Therefore, these gases need to be vented out.

Pre-1963, gasoline engines had a hose that let the  fumes vent out into the air. In 1963, the federal government required gas engines to have a special one-way valve installed to help reduce dangerous emissions. (Can you imagine how polluted our CA air would be if every car had been releasing those poisonous fumes for the last 50 years?) Diesel engines are not required to have these valves.

The positive crankcase ventilation (PCV) valve routes crankcase gases through a hose and back into the air intake system where they are re-burned in the engine. Fresh, clean air is brought into the crankcase through a breather tube. It's really a pretty simple system, but it does the job. The re-circulating air removes moisture and combustion waste from the crankcase, preventing sludge. This extends not only the life of your oil but the engine as well. The PCV relieves pressure in the crankcase, preventing  oil leaks.

Eventually, the PCV valve can get gummed up. Then it can't move enough air through the engine to keep it working properly for Thousand Oaks vehicles. If the PCV valve is sticking enough, you could have oil leaks, excess oil consumption and a fouled intake system. If you experience hesitation,  surging or an oil leak, it may be a sign of PCV valve problems. Your vehicle's owner's manual may give a recommendation for when the PCV valve should be replaced - usually between 20,000 mi/32,000 km and 50,000 mi/80,000 km. Unfortunately, some don't list a recommendation in the manual, so it can be easy to overlook.

Many PCV system problems can be diagnosed by our technicians at Niel's Auto Service . Fortunately, PCV valve replacement is both quick and inexpensive at Niel's Auto Service. Proper oil changes will greatly extend the life of the PCV valve. Skipping a few recommended oil changes can allow varnish and gum to build up in the valve, reducing its efficiency. So now when your Thousand Oaks service technician tells you its time to replace your PCV valve, you will know what he's talking about. If you have had your car for a while and this is the first you've ever heard of a PCV valve, ask your technician to check yours out or call Niel's Auto Service at 805-379-4040.

Tire Tread Depth for Thousand Oaks, CA Drivers

Driving on bald tires is like playing roulette. Though you may be fine today, eventually your luck is going to run out.

The Feds don't have any laws for tread depth, but 42 of the states, and all of Canada, do have regulations. They consider 2/32 of an inch to be the minimum legal tread depth. Two other states, including California, consider 1/32 to be the minimum and six states have no standards at all. Call us at Niel's Auto Service; (just call 805-379-4040) to find out what your requirements are in the Thousand Oaks, CA, area.

Since 1968, U.S. law has required that a raised bar be molded across all tires. When tires are worn enough that this bar becomes visible, there's just 2/32 inch/1.6 mm of tread left. But does that older standard give Thousand Oaks vehicles enough safety?

Consider this: Consumer Reports recommends tire replacement when tread reaches 4/32 inch/3.2 mm. And the recommendation is backed by some very compelling studies. Now before we go into the studies, you need to know that the issue is braking on wet surfaces.

We tend to think of the brakes doing all the stopping, but Thousand Oaks vehicles also need to have effective tires to actually stop the car. When it's wet or snowy in Thousand Oaks, CA, the tread of the tire is critical to stopping power.

Picture this: you're driving in Thousand Oaks over a water-covered stretch of road. Your tires need to be in contact with the road in order to stop. That means the tire has to channel the water away so the tire is contacting the road and not floating on a thin film of water – a condition known as hydroplaning. When there's not enough tread depth on a tire, it can't move the water out of the way and you start to hydroplane.

This is where the studies come in. We think Thousand Oaks drivers will be surprised. A section of a test track was flooded with a thin layer of water. If you laid a dime flat on the track, the water would be deep enough to surround the coin, but not enough to submerge it. 

A car and a full-sized pick-up truck were brought up to 70 mph/112 kph and then made a hard stop in the wet test area. Stopping distance and time were measured for three different tire depths. First, they tested new tires. Then tires worn to legal limits. And finally, tires with 4/32 inch/3.2 mm of tread were tested (the depth suggested by Consumer Reports.)

When the car with the legally worn tires had braked for the distance required to stop the car with new tires, it was still going 55 mph/89 kph. The stopping distance was nearly doubled. That means if you barely have room to stop with new tires, then you would hit the car in front of you at 55 mph/89 kph with the worn tires.

Now with the partially worn tires – at the depth recommended by Consumer Reports – the car was still going at 45 mph/72 kph at the point where new tires brought the car to a halt. That's a big improvement – you can see why Consumer Reports and others are calling for a new standard.

Now without going into all the details, let us tell you that stopping the truck with worn tires needed almost 1/10 of a mile (.16 km)  of clear road ahead to come to a safe stop. How many Thousand Oaks drivers follow that far behind the vehicle ahead? Obviously, this is a big safety issue.

The tests were conducted with the same vehicles but with different sets of tires. The brakes were the same, so the only variable was the tires.

How do people in Thousand Oaks know when their tires are at 4/32 inch/3.2 mm? Well, it's pretty easy. Just insert an American quarter into the tread. Put it in upside down. If the tread doesn't cover George Washington's hairline, it's time to replace your tires. With a Canadian quarter, the tread should cover the numbers in the year stamp.

Now you may remember doing that with pennies. But an American penny gives you 2/32 inch/1.6 mm to Abraham Lincoln's head. The quarter is the new standard – 4/32 inch/3.2 mm.

Tires are a big ticket item, and most people in Thousand Oaks, CA, want to get thousands of miles/kilometers out of them. Just remember: driving on bald tires is like playing roulette.

Have Mr. Washington look at your tires today. If he recommends a new set, come see us at Niel's Auto Service in Thousand Oaks.

Below 45 Degrees in Thousand Oaks: Consider Winter Tires

Remember snow tires? They were basically just regular tires with big, knobby lugs to get them through deep snow. They were loud and rode hard, and Thousand Oaks drivers couldn't wait to get them off the car. Then along came television advertisements for “all-season” radials. CA drivers ran out and bought some and we thought we were done with snow tires forever.

Tires have come a long way since then. Modern winter tires sold in the Thousand Oaks area are much better designed for the wide range of conditions that come with CA winter weather. They are made with a rubber compound that helps them stay flexible in cold weather. Regular tires become hard and stiff at Thousand Oaks temperatures below 45°F (7° C) which reduces their traction. That's a concern in winter, especially with snowy or wet conditions. But it also means that Thousand Oaks drivers are better off with winter tires in cold weather even when it's dry.

The tread design on winter tires has been improved to move snow, slush and water. The lugs and grooves throw packed snow out of the tread as the tire rotates. This means the tread is open and ready to move more snow when it rolls around again. Summer tires can pack up with snow, which makes them more dangerous than a bald tire.

The all-season tire that is popular among Thousand Oaks drivers is a compromise between summer and winter performance. This means they give adequate performance for Thousand Oaks drivers in either season but aren't great in either. Summer tires give great performance in hot weather but lousy performance in winter. Thousand Oaks drivers need to put more thought into their tire choices these days.

If you want the performance that new winter tires can give you, you should have them properly installed by your friendly and professional service advisor at Niel's Auto Service. It's best to purchase four snow tires and put them on all the wheels of your vehicle. But if you only want two, you need to put them on the rear of your vehicle, even if you drive a front-wheel drive vehicle. Thousand Oaks drivers always want to put the tires with the best traction on the rear of the vehicle.

For more auto advice about tires for any CA season, ask your friendly and knowledgeable Niel's Auto Service tire professional. They can help you find the right tire for your area and for your driving needs. For the best performance from your tires, whatever the season, don't forget preventive maintenance. Keep your tires up to pressure for the best durability, safety and performance, but don't overinflate them. Remember, good car care provides the safest road for all of us in Thousand Oaks.

The Part You've Never Seen (Flat Tires and Solutions)

They say your vehicle has one, but you've never seen it.  And you might not even know it if you stumbled on it accidentally.

We're talking about the jack, that tool that allows you to lift one corner of the vehicle up so someone can change a flat tire.

So you say you'd never try to change a flat anyway, so you don't care where it is.  But one day, you may find yourself in a spot where you're stranded with no cell service and you'll need to at least know the basics of what to do.

Well, here's the ironic part.  Many of today's vehicles don't even have jacks and spares!  Recently, manufacturers have been saving weight by supplying another solution for a flat tire, such as an inflator kit that has a tire sealant in it, or a small compressor.  If your vehicle has one of those, it's a good idea to get to know how to use it before you need to use it.  Hopefully you'll be able to call roadside assistance and they can take care of things, but circumstances may prevent help from coming for a long time. The next time you're here at Niel's Auto Service for routine maintenance, ask one of our pros to show you the basics of your vehicle's flat tire tools.  Consider watching an online video, too; there are plenty out there and may be specific to your make and model.

Some vehicles have a space-saving spare, a smaller one that is meant to get you on the road long enough to find a place to have it repaired or replaced.  Those vehicles will also have a jack.  Then there are vehicles that have a full-size spare tire and a jack.  Again, you may prefer to call roadside assistance, but if no one is available or reachable (which is sometimes the case in a major storm), you may have to fix your own flat.

Some drivers do a "dry run" of changing a tire in their driveway during daylight hours so they at least know where the jack and spare are and how to use them.   Our service experts may be able to help you locate each part and give you some tips.  And again, there are many videos online that can show you the fundamentals of jacking your make and model of vehicle. 

Nobody relishes a flat tire.  You may be lucky and never have to change one.  But in this case, a little knowledge is better than no knowledge at all.  In the unlikely case you are stranded at the side of a highway at night in the middle of the rain with no cell service, you'll at least be one step ahead.
