PCV Valve Replacement

Hello St. Peter auto owners, 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. Cleveland folks know that sludge is one of the biggest enemies of your engine, clogging it up, eventually leading to expensive failures. Also, the pressure build up 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 harmful 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 Cleveland air would be if every car had been releasing those poisonous fumes for the last fifty years?) Diesel engines are not required to have these valves.

The positive crankcase ventilation, or 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 harmful 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 St. Peter car owners. If the PCV valve is sticking enough, you could have oil leaks, excess oil consumption and a fouled intake system. If you experience hesitation or surging or an oil leak, it may be a sign of PCV valve problems. Your auto manufacturer’s owners’ 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 auto manufacturers don’t list a recommendation in the manual, so it can be easy to overlook.

Many PCV system problems can be diagnosed with an automotive analysis by your knowledgeable Autotronics of ST Peter tech. Fortunately, PCV valve replacement is both quick and inexpensive at Autotronics of ST Peter. 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 St. Peter 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 value, ask your service advisor to check yours out or call Autotronics of ST Peter at 507.934.9290.

Exhaust Service At Autotronics of ST Peter In St. Peter

Whenever they hear the term “exhaust service,” most St. Peter car owners think about exhaust pipes and mufflers. Well, actually, exhaust service at Autotronics of ST Peter 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 vehicle 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 vehicle manufacturer recommends you have your emission system checked out by a qualified St. Peter 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 Autotronics of ST Peter in St. Peter 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 Autotronics of ST Peter at 507.934.9290 to schedule an appointment if you experience these problems.

Let’s review the exhaust system. We will start from the top and start with the exhaust manifold. That is the critical 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, detrimental 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 St. Peter environment into harmless carbon dioxide and water. It doesn’t require any maintenance itself. But eventually they wear out. St. Peter motorists 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 knowledgeable Autotronics of ST Peter service professional.

The exhaust system is attached to the minivan 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 Autotronics of ST Peter in St. Peter 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.

Power Steering Service In St. Peter

Most St. Peter auto owners are too young to remember life before power steering – cranking those great big steering wheels! It was a pretty good workout. Now power steering is standard. Let’s look at how it works. The heart of any power steering system is its pump. The pump pressurizes the power steering fluid that provides assist for steering. Most pumps are driven by a belt that is run by the engine – a few are electrically powered. A high-pressure hose passes fluid from the pump to the steering gear. A low pressure hose returns the fluid back to the pump.

These hoses can develop leaks, so it is a good idea fir St. Peter auto owners to have them inspected at every oil change. Low fluid can damage the power steering pump. That is why fluid level is on the checklist for a full-service oil change. The fluid needs to be compatible with the hoses and seals, so check your owners’ manual for the right type – or just ask your knowledgeable service advisor at Autotronics of ST Peter in St. Peter.

The fluid cleans, cools and lubricates the power steering system. It breaks down as the years go by and collects unwanted moisture, so St. Peter auto owners need to replace it from time to time. Many auto manufacturers specify power steering service intervals. Unfortunately, this important service is sometimes left off the car maintenance schedule for many of us in Cleveland. So, when in doubt, every 25,000 miles/40,000 km or two years is a good fallback. Your knowledgeable Autotronics of ST Peter tech will use a detergent to clean the system, flush out the old fluid and replace it with the good stuff.

Here are some important warning signs of trouble with your power steering: It’s harder to turn the wheel, there’s erratic power assist, you hear loud whining coming from the pump (which may be difficult to hear over the loud whining coming from the backseat), you have to top-off the fluid frequently, or you hear squealing belts. Remember to never hold the steering wheel to the far right or left for more than a few seconds at a time. That will wear out your power steering pump real fast.

Other essential steering components can be bent or damaged from wear or hard knocks. Ball-joint, idler-arm, steering-gear, steering-knuckle and tie rod to name a few. Warning signs here are steering play, wandering, uneven tire wear, and off-center steering wheel. An annual alignment check at Autotronics of ST Peter in St. Peter will reveal bent or damaged steering components.

Most SUV’s, pick-ups and rear-wheel-drive cars need regular front-wheel-bearing service.

The bearings should be cleaned and inspected. If they are excessively worn, they need to be replaced. The bearings are then repacked in clean grease. The team at Autotronics of ST Peter also recommends the wheel-seal be replaced when the bearings are serviced. Like everything else, check your owners’ manual maintenance schedule. It’s usually required around every two years or 40,000 miles/64,000 km. If you drive through water in the Cleveland area, the bearings will need service more often.
