Should be on the passenger side valve cover. It will have a hose running to it and you will be able to pull it out without any tools. One way to check if the valve is still good or not is to shake it and if it still moves freely, then its okay. Since they are fairly inexpensive, I always replace mine anyways. Hope this helps and good luck!

My 2000 ford excursion 5.4 v8 gas has a problem at idle every time i come to a stop the idle remains at 1300 rpm for about 2mins then slowly returns to 7000 rpm also has slight miss on accell

Ethanol gas syndrome/ buy a can of SEAFOAM(parts store). change out the fuel filter. add SEAFOAM to full tank of PREMIUM gas. let it idle(even if you have to make it by acceleration in park)/ drive 10 miles, replace fuel filter again at 500 miles. add can of SEAFOAM every 3-5000 miles, and it will clean fuel,emission, and engine valves.<p>
ethanol produces a goop(like choc milk) and creates water in the system/ It causes carbon build up and even affects injectors. If you will try this, it will help prevent costly repairs/ cost 8-9 dollars for the SF. whole lot cheaper than an engine job. good luck.

Smoking engine when first started V-10 gasoline.

well if it is only smoking when you first start it and it clears up after the engine warms up the first thing you need to check is your coolant level could be head gaskets

2003 Ford Ranger 2.3 Diagram

 rough-idling engine can signal a number of positive crankcase ventilation (PCV) valve problems, such as a clogged valve or a plugged hose. But before beginning the functional checks, double check the PCV valve part number to make certain the correct valve is installed. If the correct valve is being used, continue by disconnecting the PCV valve from the valve cover, intake manifold, or hose. Start the engine and let it run at idle. If the PCV valve is not clogged, a hissing is heard as air passes through the valve. Place a finger over the end of the valve to check for vacuum.


With the engine at idle, vacuum should be felt at the PCV valve.

PCV Valve location diagram.....

  I will assume you you have the Duratec engine (24 valve). It is located under the intake manifold on the transmission side of the engine. Real tough to get out without some real long pliers with a ring type end on it. It needs to be twisted counterclockwise to release it. replace the hose to it while you are there also , they degrade and will cause a vacuum leak.

2001 ford focus dohc

Easiest way to find the PCV on a 2000 ZX3 (ZTEC engine)is to stand directly in front of the engine and look at the right side of the oil filler cap. From there, approx 10 inches directly below the the right side of the cap, you will see a black rubber hose/tube (3/4 inches)inserted into a rubber grommet--the PCV valve!! If you were to follow the hose/tube back through the emission components, you would find it connects to the lower rear of the throttle body.
