Crankcases and PCV Valves

I was just told where the PCV valve(s)are on my 2000 Lincoln LS by the Service representative of my local Ford dealer. Apparently there are two PCVs. Each is an integral part of the valve cover(s). They tell me that they cannot be replaced without replacing the complete covers. (What a bad design ?). I am finding all this all out the hard way. They tell me that both PCVs are carboned up and plugged. That in turn has created backpressure in the engine and under the valve covers. This has resulted not only in blowing the seals (gaskets?) on the valve covers, but also in filling up one of the plug wells with oil (yes, the spark plugs are under the covers on the LS), and caused a misfiring of the sparkplug. I have been experiencing this misfiring at certain engine speeds during the last few weeks. Also, there has been a faint smell of oil fumes coming from the engine recently. The repair is going to consist of 2 new Covers (c/w PCV valves), new spark plugs, and at least one sparkplug coil. Estimated Cost of repair : $1,100 !! Anyone have any comments ?

The PCV valve is located just to the right of the alternator...take off the 3800 cover (usually gray in color), and its behind the alternator and to the right of it, and you will see it popping out of the engine block right on the top of the engine case....its best to remove the alternator...u have to remove it to get to the pcv valve and replace it....

The PCV Valve is on top of the breather cannister which is located under the right side (Passenger side) Carb to the right of the oil filter. You can view a diagram at the link lsited beklow .

Yes. Remove it, shake it. It should make a rattling noise. It could be plugged up. Just install a new one. They only cost about 10 dollars.

It's located on top of the valve cover - note that it's not a rubber PCV valve like a lot of other cars, it's fully metal, and costs a little more. I got my new PCV valve in Advance Auto parts (My local Autozone had one that did not match what was on my car.

The pcv valve is located in the cam cover of the engine. The cam cover is also where your oil filler cap is located. Look over to the right of the filler cap. You will see a grey plastic piece stuck into a rubber grommet in the cam cover. This is the pcv valve. Pull it out of it's grommet, remove the hose from the other end, and re-install in the same order. To make your new valve slide easily into the hose and grommet, just spit on the valve housing, being careful not to get it into the valve body. That's it!

you can see the valve on the fuel injector. it is on the passenger side of the car and to the front of the injector.

Just had the same thing, engine cut out after 15 miles, depending on how long i leave it before turning the engine over again depends how long it will stay running.

Resolved by replacing the crank shaft sensor.

After the machanic replaced the crank sensor, I now have no speedo or cigarette lighter.. not sure about that one.

the pcv valve is on the ight hand or drivers side of the valve cover with a rubberhose connected to it it is shaped like a nut or bolt head so u can tighten it it just a plastic check valve. there like $6 at dodge. If it is a SOHC answer could be here. http://www.techknowman.com/Dodge%20Neon/Dodge%20Neon.htm

standing in front of car, on left side of upper intake(black plastic) is your map sensor. unplug electrical connection, turn map sensor and mounting bracket counter clockwise and pull up to remove, being careful not to lose spring and o rings.pcv is located in this hole under spring. reinstall all o rings and spring or you will get crankcase vacuum and engine noise On my 92, it's on top of the motor where it say 3800(engine size)facing the motor it's on the left -PCV inscribed on the plastic/metal cover. It's under a cover with a spring.

On the oil fill cap side of the valve cover. To access the PCV valve you will need to remove the protective plastic cover mounted over the valve cover area.Two small nuts are holding it in place. Unlike other PCV valves you may have changed in the past, this one is screwed into the valve cover instead of being inserted into a rubber grommet. You will need a 22MM deep socket or a suitable wrench to remove it.

Where's the PCV valve located on a 2004 Toyota Sienna van

It is supposed to rattle when you shake it. if it does not, it needs replacing. The rattle you hear is the check valve.

Your Prizm may not have one. Check the valve cover or the intake valve cover on twin cam For a vacuum hose leading to the intake. The PCV should be installed in the cover with hose connected. If cover only has tubing permanently mounted then you vehicle has no PCV valve.

If you go to www.automirrorglassonly.com it will tell you how to replace the mirror glass for the outside mirror. You can buy one there too.

The outside mirror is just glued on , some parts stores sell replacement glass and you can glue the new one on

It is in a hose that is stuck in the top of the drivers side valve cover.

there is no crank case drain plug on your engine, only a plugged drain line coming from your oil tank.

Better heat distribution. The exhaust valve sees a lot more heat.

Inlet & exhaust valves operate in different pressure conditions. Inlet valve in NA engines (Normally aspirated engines) have to work against pressure difference of say vacuum caused by piston going down & atmospheric 1 bar pressure, ie at pressure difference of 1 bar while exhaust valve has to work against pressure of multiple times of 1 bar. So exhaust at high pressure has a tendency of getting exhaled faster.

During designing of valve size, amount of force required to operate the valves during operation is also considered so higher the area of exhaust valve higher is the force required to operate it.

Thirdly Valve overlap timing requirement & the dynamics of the flow of air and physical sizes of valve opening affects each other or dependent of each other

The exhaust valves will be located closest to the exhaust manifold side of the head & are always smaller in diameter than intake valves.

Also if any are open @ the time you will see the carbon build up around the exhaust valves

where as the intakes will be considerably cleaner.

I have a 5.8L in my 1990 and it is located behind the intake on the passenger side. Right by the valve cover.

On a lot of these vehicles, the PVC valve is located on top of the valve cover, or a hose leading from the valve cover to the intake. You have to remove the right front wheel. It will be in the block. It is in an awkward place and Nissan charges about a 100.00 to install it. You can do it your self though.

The purpose of a bearing is to reduce friction, most often on a rotating shaft. It may be made of many different materials including sintered bronze, which holds oil to reduce friction, and various metals which are cast in place to make a soft slippery surface for really heavy shafts. A bearing can also use balls or rods between two hardened metal surfaces, the balls or rollers convert what would be a sliding contact to a rolling point contact.

The PCV on a 1994 Mustang 302 is located on the rear of the lower intake plenum. It fits into a rubber grommet and has a right-angle hose leading off of it.

No, on the 3S-FE there is no PCV valve or grommet. This is the 4cylinder model. The camry V6 of the same year on the other hand, does utilize a PCV valve in its crankcase ventilation system.
