Please help me figure out where my PCV valve and PCV Hose is!!!
Please help me find my PCV valve and PCV valve hose is my car has an after market engine cover so the PCV valve isn't in the usual spot like I've researched my car is idling funny and the diagnostic check came back as the engine was running to lean and I researched that on the Ford Taurus it's usually the PCV valve or hose. I have looked every under the hood of my car for the PCV valve or hose and I can't figure out where it is please help Thank you!!
My car has 168433 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hi there. The PCV valve is located on bank 1; the valve cover closest to the cabin. It is usually found under the intake plenum towards the passenger side of the vehicle. The hose will be attached; or loose. Please understand that a code retrieval and an internet search is not a proper diagnosis as there are several other possibilities that can cause the code to set. Some of the possible causes could be spark plugs, ignition coils, intake manifold leaks, intake plenum leaks, vacuum hose leaks, failing airflow meter, failing O2 sensors, exhaust manifold leaks, low fuel pressure, failing ECU, faulty wiring harness, failing injectors, etc… As you can see, the list of possibilities runs on and on. This is where the expertise and experience of a qualified technician with the proper diagnostic tools and procedures becomes invaluable. I strongly suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts and determine the exact cause of the code. Your Mechanic has several available technicians that can assist you with a check engine light inspection.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
The Positive Crankcase Ventilation (PCV) valve hose is a hose running from the valve cover on the engine to either the intake air box or the intake manifold.
Where is the PCV valve located in my 2003 Ford Taurus? Assuming you have a DOHC engine. If memory serves,it`s at the rear center of the engine. Accessible by removing the upper manifold section.
Common signs of a faulty PCV valve include excessive oil consumption, oil leaking, a blocked breather filter, and reduction in overall performance.
There are a total of 5 hoses:
(1) 11823-30P20 – Passenger side, from valve cover. (2) 11823-30P01 – Passenger side, directly on the PCV valve. (3) 11823-30P11 – Drivers side, directly on the PCV valve. (4) 11826-30P10 – On backside of engine.
The fuel hose is designed for internal pressure. It will collapse under the vacuum of the PCV system. PCV hose is designed specifically so it won`t collapse. So insist on PCV hose, never fuel hose or vacuum hose.
A PCV valve that`s stuck open will allow too much air to enter the intake manifold, leading to a leaner idling fuel-air mixture. Stuck closed leads to a build up of pressure in the crank case which creates a variety of oil leaks! And this in turn can lead to a range of issues, including a rough idle.
Hold the tube at an angle and introduce the microhaematocrit (capillary) tube. Allow blood to track up the tube. Continue until the tube is about 3/4 full. Put your index finger over the top of the capillary tube before removing it from the sample or blood will leak!
The PCV valve regulates how much vacuum can pull through the crankcase. It`s hooked into the intake – when the vacuum is high at idle, the PCV valve stops most of that vacuum. As vacuum drops with an increase in RPM, The PCV valve opens, to allow a higher volume of gasses and pressure to be pulled into the intake.
Bad PCV valves can cause engine oil contamination, sludge build-up, oil leaks, high fuel consumption, and other engine-damaging problems, depending on the type of failure.
However, a bad PCV valve is a tiny, inexpensive part that can cause an engine to burn oil if it goes bad. Replacing it is fast and easy! If your engine is burning oil, hope that it`s due to a bad PCV valve.
A typical PCV system should be pulling about 1 to 3 inches of vacuum in the crankcase at idle. If you see a significantly higher vacuum reading, the intake manifold gasket is probably leaking and pulling vacuum on the crankcase.
The pressure control valve is used to regulate the pressure of a fluid passing through the pipe. A pressure control valve (PCV) opens and closes based on the setpoint predetermined by an engineer. This is usually controlled using a pressure transmitter (PT).
Answer: A silicone hose cannot be used to replace a PCV hose. Silicone hoses cannot be used for oil and fuel applications.
Yes, it`s possible to create your own custom hoses. PCV hoses can be anything from a short run of hose to a complex pipe with brackets depending on the car, so there`s really no one general answer.
Whether due to clogging or mechanical failure, a stuck or clogged PCV valve can lead to a lot of additional problems. Two of these that can cost you additional money include increased fuel consumption and increased oil consumption.
When your PCV valve is malfunctioning, it throws the air to fuel mixture out of balance and can lead to poor performance and rough idle, as well as misfires. In the very short term, these issues should not damage your car, but if you don`t fix the issue, you can do lasting damage, so it`s best to get it fixed promptly.
The PCV valve controls the flow of crankcase gases entering the intake system. At idle, with almost closed throttle, the manifold vacuum is high, which would draw in a large quantity of crankcase gases, causing the engine to run too lean.
The Breather Element is typically a paper or foam element that helps filter the air pulled into the engine crankcase by the Positive Crankcase Ventilation (PCV) system.
NO. The PCV (Positive Crankcase Ventilation) valve is necessary to maintain steady oil pressure in your system, to maintain oil seal integrity throughout your engine, to maintain correct emissions levels and to prevent excessive engine wear.
PCV = height of red blood cell column x 100% divided by total height of blood column.
Installation position of the PCV valve on the cylinder head. In vehicles with turbochargers, power loss, rough idling, or whistling noises are indicators of a defective crankcase ventilation system, MAHLE Aftermarket reports.
A stuck closed PCV valve results in excessive crankcase pressure. It forces oil past the engine`s seals and gaskets. A stuck open PCV valve or leaking hose results in a large vacuum leak, a rough idle, and drivability issues like surging.
If you hear a hissing sound from the engine, it is time to get your vehicle looked at. The PCV valve hose may have a leak in it, which is causing the hissing sound. Leaving this for too long can cause misfires, rough running, vacuum leaks and you will have a more extensive repair on your hands.

Is the pcv supposed to fit loose on the valve cover? And how do you remove the pcv itself?
ANSWER : The PCV on this engine has a lock tab and unscrews from the valve cover. The tab may break when you try and remove it so make sure you have the correct one before you try and remove the old one. It will have what looks like threads on the bottom of the valve and will screw into the valve cover with a half turn and locks in place. To remove it, lift and turn counter clockwise and pull out. It will have an O-ring to seal it on the valve cover. If you end up needing some help with this, consider YourMechanic, as a certified technician can come to you and assist you with servicing your PCV valve.

PCV valve hose collapses
ANSWER : I am guessing your PCV collapsed because it is old and weak. This will cause your PCV to collapse while it is in vacuum. I would recommend going to your local auto parts store and picking up a reinforced braided hose. These have a solid structure that will not collapse under vacuum. They will also be able to cut and match the length of your existing hose. Also, make sure the hose is sealed on both ends to ensure that there are no leaks. If you are in doubtful about this repair, I would recommend enlisting the assistance of a qualified professional in order to guide you through proper replacement of the PCV valve hose.

installing a upper radiator hose, about an inch down the piece you slide the hose over has a raised lip, do i slide hose over lip
ANSWER : Hello, thank you for writing in. Correct, you want to place the hose clamp between the two raised lips. If the hose will willfully go over the second lip, that is fine. The goal is to have the hose beyond the first lip, and have that lip there to give the clamp something to hold the hose on with. The second lip is to give an area for the hose to recede down into so the hose clamp can get a good grip. The longer the hose stays in place, the more the hose will form to the area giving you a good seal.

Pcv valve problem
ANSWER : Hello. In most case a PCV valve should not noticeably rattle, though that varies from engine to engine. If it appears to be rattling excessively that could signify that the PCV valve is not secured properly, that there is a vacuum leak, or that the internal spring is weak or broken, and that the valve needs to be replaced.. An excessively rattling PCV valve could cause an unstable idle, hesitation, and oil consumption. A code for the EVAP system will usually be a separate issue from that of the PCV valve. If the code came on after working on the PCV valve, I would carefully check to see if there are any vacuum hoses or emissions hardlines that run near the PCV valve to see if they may be damaged or broken. If not, it may be possible that the EVAP leak is elsewhere. I would recommend having a professional technician, such as one from YourMechanic, come to your location to determine the cause of the PCV valve rattling, and if it may be related to the trouble code.

PCV valve or hose failure?
ANSWER : Hello. The PCV valve regulates the flow of crankcase fumes to the engine to be burned when there is greater pressure in the crankcase than there is in the engine intake – which is most of the time. If the engine has worn piston rings, there is more combustion gases (also known as "blow by") and pressure in the crankcase, so more oil fumes are vented to the engine, gunking up the throttle body, idle air control valve, mass air flow sensor, etc.
This is somewhat normal over the life of the engine, but also indicates an engine wear condition. Perhaps the hose you mention is a generic hose bent from a straight piece, and instead should be a molded hose that is pre-bent to the correct shape, and has good flow? Check that out. I would recommend having a rough idle inspection completed by a mobile, professional mechanic, such as one from YourMechanic. They will be able to come to your location, diagnose this problem, give you an accurate assessment of damage and cost for repairs.
