Even more importantly, it'll prevent serious engine damage and expensive repairs. During operation, the EGR system pulls a small amount of exhaust gases from the exhaust manifold through the EGR valve, into the intake manifold, and back into the combustion chambers. Theses gases mix with the air-fuel mixture inside the cylinders to reduce high temperatures during the combustion process. The lowered temperature inhibits the formation of poisonous oxides of nitrogen NOx.

Overtime, though, this routed gases build up a hard and thick wall of carbon, locking the EGR valve opened or closed and obstructing system passages, which prevents exhaust gases from reaching the combustion chambers and increases NOx emissions. That's why car manufacturers recommend cleaning the EGR valve and passages every 50, miles or fewer.

But you don't need to take your car to the shop. By the end of your repair, you'll have restored engine performance and saved your engine—and your wallet—from irreversible damage. Depending on your car's make and model, your engine may be using one of three common types of EGR valves: vacuum controlled older modelselectronic-vacuum controlled valve newer modelsor the new electronic controlled digital valve.

You'll locate the valve towards the top or side of the engine. However, one or more components may obstruct your view. Look around the side of the cylinder head top area of the engine for the valve. Check near the throttle body, firewall, or intake manifold. If you don't see it, search for your EGR valve online by going to an auto parts store website and entering your car's make, model and engine size to look for the valve. Most auto parts stores will show the picture of the EGR valve that applies to a particular vehicle make and model for quick identification.

Look at the picture and you'll know exactly what you're looking for. Or, better yet, consult the repair manual for your particular vehicle make and model. You can buy an inexpensive aftermarket repair manual at most auto parts stores and online. The manual tells you not only the location but provides illustrations and photos of the valve and related components, troubleshooting procedures, and the necessary steps to remove and replace EGR system components like the EGR sensor, vacuum hoses, and pipes.

A PCV valve helps keep a constant pressure within the engine block by releasing oil fumes when they get to a certain pressure and sending them into the fuel system to be reburned with the gas. While they can be inexpensive, they can be very hard to locate and remove on several makes of cars and trucks. Some are internal and cannot be replaced, meaning they are located inside the valve cover.

The PCVs that can be replaced should be replaced every 15 to 60 thousand miles depending on the make and engine you have. It stands for positive crankcase ventilation.

And what they told u was right about replacing it. All it does is prevent condensation build up and burn fuel fimes that get by the rings. The condensation will build up and create sludge and that is a bad thing because it will block oil galleries and return holes and ur engine will run oil dry and it will be fried.

The PCV Valve, or Positive Crankcase Ventilation valve is an emission control device that routes unburned crankcase blowby gases back into the intake manifold where they can be reburned.

The PCV system is one of the oldest emission control devices, and also one of the most beneficial. Besides totally eliminating crankcase emissions as a source of air pollution, the constant recirculation of air through the crankcase helps remove moisture which otherwise would cause sludge to form.Many Nissan owners have reported excessive oil consumption for, and models like Maxima, Altima, Pathfinders, etc.

I believe that, with the help of the right mechanic, I have discovered the cause and why it has been so elusive.

The story should rightly infuriate many owners who have spent so much money trying to fix the issue. I had the same oil consumption problem with my Maxima. Each time I went to the dealer, they basically played dumb as to what could be causing the problem.

There were no external signs - no leaking, no smoke, etc. When I asked if they had ever seen anything like it - there answer was no. When I asked what is the usual cause?

Their response was that owners were not changing oil at required intervals. The problem with excessive oil consumption that became noticeable at around 70, miles, eventually took my engine out. Luckily, I removed it from the Nissan dealership where it was towed and had it taken to a garage - owned by a Nissan trained mechanic - previously trained at that same dealership. He recognized the underlying cause. The excessive oil consumption was caused by faulty catalytic converter design.

As the catalytic converters aged, they produced a sand like substance that was being sucked back into the engine during the common negative cycle. This created a comet like substance that created excessive internal engine wear.

As engine oil was drawn into areas it should not be and burned off, it further accelerated the catalytic breakdown process.
