SOURCE: where is the pcv valve on the 2005 chevy trail blazer

It is located on top of the valve cover. Buy the new one and you will see what it looks like, then you will pull the hose off of it and put the new one on, 5-minutes at top to do this job.

SOURCE: PCV VALVE REPLACEMENT

The pcv valve is usually located on one of the valve covers look for the larger vacuum hose coming from the intake manifold and follow it you should find it that way. changing it is a matter of sometimes using a pair of pliers to remove a small clamp then rotate back and forth the pcv valve while holding the hose and pulling it away and off.

it should be in the top of the intake manifold, the air cleaner tube goes into the throttle body and there is a little line that runs from the air cleaner tube into the pcv value and is screwed into the intake manifold.

90k , timing belt new @ 80k worked fine sprayed engine with water to clean dust started and ran fine nest day started but then idled up to 4k and wouldn't idle down drove it about 5 miles and got off...


I have ran into this problem at my shop. There are 3 things that could be bad. Idle air control valve, pcv valve or the vacum hose for the pcv valve. Vicually inspect the pcv vale hoses. If you dont see a tear, spray carb cleaner around the hose, if engine idle changes there is a vacum leak in hose some where. If pcv valve and hose are ok than its your idle air control valve. You can attempt to remove part and clean it but this is only a temporary fix, Good luck.

    Remove PCV valve from rocker cover. Run engine at i

    check for vacuum. If there is no vacuum at valve, c

    valve. Repair or replace as necessary.

    Turn engine off. Remove PCV valve. Shake valve and
    listen for rattle of check valve inside. If a clear
    rattle is not heard, replace PCV valve.

    Visually inspect valve for varnish or deposits whic

    properly, check engine for cause and repair as requ

    properly. An engine operating without any crankcase
    ventilation can be damaged so it is important to
    replace PCV valve and air cleaner breather at regul
    ar intervals (at least every 30,000 miles). Check a

    and clamps for failure or deterioration.

    Heavy black smoke/lack of power


    bad injector stuck rings with carbon build up ty doing a top engine clean to free up rings, also check PCV valve to see if it is defective when you remove it and shake it it should rattle if not it's plugged. Black smoke is indicative of over fueling or burning oil. Is the oil black? Also burnt valves could do this, is it using oil? if not let me know so we check more items seems to me they had an issue with the PCV VALVE OR HOSE OR BOTH.

    How difficult is it to change the PCV valve. 2004


    PCV is an acronym for positive crankcase ventilation.
    The PCV Valve is a very common replacement item on many engines today. It's called the PCV valve for short but it stands for Positive Crankcase Ventilation. When your engine spins it many times collects pressure in the crankcase area, and it has to escape to relieve pressure on the motors bearings and seals. The PCV valve and PCV system is typically located near the intake manifold, and many times comes right off of the valve cover. It is very simple to replace the PCV valve, and you can do so by simply unscrewing it, and screwing in the new valve. We recommend using a little bit of teflon tape or paste to make sure you do not get any oil leaks.

    Want to locate pvc valve on 2000 pontiac grand am 6 cyl


    You'll find the PCV valve on the right side of the front valve cover. You'll need to remove the valve in order to troubleshoot it to determine if you need a replacement. To remove, pull the PCV valve out of the cover and detach the hose

    Test the old PCV valve to determine if it needs replacing. Blow air through it in order to see if it is clogged. If it does not seem to ventilate, then you'll need to install a new valve.

    Pop the new PCV valve into the spot of the old valve. With the correct part, it should snap right in. Take the hose and reattach it in order to complete the installation.

    How do I remove the pcv valve from a 3.8 liter engine in a 2005 dodge grand caravan? I cannot pull it out.


    1. BUY THE NEW PCV VALVE FROM THE DEALER. part #4648973AC (I paid $9.95 in the Detroit area). 2. PCV valve is located on top of 'rear' valve cover. There is a black rubber pipe connecting the PCV to the upper intake manifold. The rubber pipe is like an inverted 'U' shape. 3. To remove the rubber pipe, you will need to squeeze the band clamps. Remove the upper end first. You will then be able to rotate the lower end clockwise, if necessary, to get enough clearance to use pliers to squeeze the band clamp. Remove the pipe. 4. You should be able to see the small chrome pipe on the end of the PCV valve. However, the PCV valve is completely surrounded by a plastic collar/shroud, part of the plastic valve cover. So, the only part of the PCV that is accessible is the small chrome pipe. 5. THIS IS WHY YOU NEED TO BY THE NEW PART FIRST. I needed to clamp onto the end of the PCV pipe with VISE-GRIPS. This will crush the end of the pipe. You will hold the vise grips in a horizontal fashion, towards your right, in your right hand. 6. Rocking the pipe, while carefully levering the vise grips on top of the plastic collar, you will walk the PCV valve up, and out. BE PATIENT. You do not want to crack the valve cover! 7. The rubber grommet should come out with the PCV metal valve. If not, you will need to pull it out (needle nose pliers?). 8. Install the new PCV valve. I used a film of white lithium spray to help the insertion. Note, there is a groove molded into the rubber grommet that must snap into place. I used a 5/8" deepwell socket as a 'pusher', to ease the PCV valve into place (just push, do not hammer). You should be able to feel it positively snap into place inside the plastic collar, otherwise it is not properly installed and will not seal. If properly installed, you will not be able to pull it out by hand. 9. Install the PCV rubber pipe. Slide the clamps towards the middle of the pipe, fit the pipe over PCVvalve. Be sure it is seated all the way to the bottom of the plastic collar. Squeeze the clamp and work down to the bottom of the pipe, then release. Repeat for the upper end of the pipe and spring clamp. 10. Have a cold one. You earned it.

    Pcv valve


    It may be that the rubber grommet that the PCV valve plugs in to is aged and brittle, preventing the collar on the PCV valve from coming through. You may need to remove both the valve and the grommet and purchase a replacement grommet that is more pliable and allows the valve to be mounted more easily.
