Most Positive Crankcase Ventalation valves are located for the valve cover into the intake air somwhere closde to the intalke manifold. They pop out  on both the hoze end and on the valve cover end,with out need of tools. . If you shake a pcv valve and the ball inside you can hear move. It is OK and need not be replaced. I have 188k on mine. It has never been replaced.

Tip

PCV - Positive Crankcase Ventilation valve/pipe


1.8) PCV - Positive Crankcase Ventilation valve

What is it? The PCV valve is a thumb sizedplastic elbow that is designed to relieve the build up of pressure in the crankcase. A pipe connects the PCV to the airducting. The function of the PCV is toreturn exhaust gases (blow-by of the piston rings during ignition) from thecrank case to the air intake.

Where is it located? PCV is found on the crankcasebreather pipe or cam cover

How does it work? Some pressure relief systems have a convoluted set of internalpassageways within the crankcase to allow oil mist to settle out and to allow excess pressure tovent in an unrestricted manner through a pipe directly into the air ducting. On other systems thePCV opens when the vacuum in the inlet manifold is low i.e. when the engine isrunning at speed and when the positive pressure of blow-by gases builds up inthe crank case. The PCV is held closefor the most part by the vacuum of the inlet manifold at idle. Often the PCV is unidirectional, allowing gas/airto flow only from the crankcase to the throttle intake. If the valve becomes clogged and stays closedthis can cause pressure buildup in the crankcase and this in turn causes oil toleak through seals etc. Alternatively ifthe valve stays open the ingress of unmetered air can upset thefuel/mix and cause rough idling.

Symptoms of faulty PCV

  • Erratic idling - If the PCV fails to close when at idle then the extra flow of unmetered air from the crankcase can compromise the ECU's ability to maintain a balanced fuel to air mixture. The symptoms very much mimic a leak in the air ducting.

How to check? Remove the PCV and first give is ashake, if it rattles freely this is a good sign. No rattle could indicate a gummed upvalve. **** and blow though it, one way should be easy the other way difficult. If the type of PCV is governed by a vacuumline then the passage of air through the valve will be restricted until asuitable vacuum is applied to it.

How to fix? It may be possible to repair the PCV by rinsing it out with a little fuel or carburetor choke spray to act as a solvent on the oily gunk that has gummed it up. If the valve is beyond reasonable repair then replace it.

1999 Suzuki Grand Vitara just had the engine replaced, but it is burning oil out the tailpipe the warranty company is saying it is the value covers, is this true


Valve covers leaking oil OUT the tail pipe, no way in hell! Valve covers can leak oil onto the exhaust manifold, but there is no way its going to get into the exhaust from there and out the tail pipe.

Bad valve guides and/or valve guide seals would put oil from the top of the head and into the cylinders. That is a far bigger job than just replacing valve cover gaskets.

Don't let the warranty company give you any more of that kind of BS.

Can u please tell me where the pcv valve go


It`s very easy, follow the air filter / air inlet pipe (black,rubber about 4`` wide on the driver`s side) it goes to the throtlle body housing where your gas cable and cruise control is located. From this black inlet pipe you will see another black plastic tube that goes directly on top of the front valve-cover gasket (front of engine) Pull this tube which is angled and you will have your pcv valve plugged into this plastic tube. Purchase the pcv valve first so you can see the size and diameter of where this tube actually will fit.
good-luck, if you cannot locate the pcv valve then I suggest to wait for your next oil change where you can ask your repair shop for the location of the pcv, and or they can replace it. Usually there`s no charge for labour it`s very easy on this engine..

MY SUZUKI GET TOO MUCH WHITE SMOKE,BUT I HAVE PUT ENGIN FLUSH, CHANGE THE OIL AND THE OIL FILTER,ADD ANTISMOKE TO FUEL BUT NO CHANGES PLEASE!!!


There has been an issue of Suzuki engines smoking due to the PCV. valve or the baffles under the valve cover. One method of curing this is to place an oil separator between the vacuum line from the intake and the PCV. This will make for the need to keep an eye on it as it will fill up with oil eventually thus negating the purpose of placing it there in the first place. I think the big fix would be to remove the valve cover and check the oil baffles and filter therein. The problem is that oil builds up at the location of the PCV and is getting sucked into the intake via the vacuum hose to the intake. The quick fix? unplug the PCV and plug up the vacuum hose to the intake. This will get you by until you can get it to a mechanic. Anyway, That what I know. hope it helps

Where is the pcv valve located on a 1999 ford explorer? Is there a picture?


PCV BasicsPCV stands for Positive Crankcase Ventilation.
All car engines have a PCV valve and it is located on top of the motor's valve cover. There is a vacuum line attached to it. It pulls out of the valve cover and if you shake it, you should hear a marble knocking inside it. If you shake it and don't hear anything, it's bad. It costs less than 5 bucks to replace.

Location
  • 4.0L is located in the valve cover near the brake booster

  • 5.0L is located behind the intake manifold (engine rear)

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.

1994 Suzuki Vitara V6 H20A Engine smoking intermittently from exhaust


I have a Mazda which in Australia (here) is called a 323 Astina, overseas a 323f, Familia, etc.
It uses a 2.0L Mazda KF Engine very similar to (in fact co-developed with) the Suzuki H20A engine, except designed to be transverse, variable resonance induction and other different tuning inc. 7000 redline, and probably not as reliable as an H20A.
I've had the engine rebuilt because I want to keep this car for a while and it needed it. Oil slipped past the rings which burned out grooves on one of the exhaust valves on Cyl-6 to the point where that cylinder had no compression...
... but I still get smoke occasionally, as you describe yours except not as often nor on the open road at speed. It happened ever since the first time I changed the oil after the rebuild. The tech who rebuilt it used a grade of oil I couldn't find and, liking synthetics, I used a lighter oil.
About the time you were writing your message, I replaced the rubber intake pipe feeding the throttle body and I noticed the inside of the intake manifold lined liberally with oil. The old pipe had oil only at one end.
The pipe I replaced didn't just go from the air mass sensor on the filter box to the throttle body. There was also a large pipe to an air reservoir (a lengthy pipe sealed at one end so that if you open the throttle quickly, you don't have to wait for more air to be filtered before it enters the engine, supposedly) and a tiny pipe to PCV valve.
It's not a long pipe so it's easy to look inside. The reason I'm boring you with all of that detail is because you'll almost certainly have a different one, but this is still most probably something you'll find feeding your intake manifold a supply of oil. The PCV (Positive Crankcase Ventilation) valve runs from one of the rocker covers (not that we have rockers) into a pipe feeding into this intake pipe. It's supposed to **** air in from the intake pipe due to a vacuum created by another pipe connecting from another part of the crankcase to the intake manifold (after the throttle body so it has a lower pressure than the intake pipe) and that might be happening in my engine but oil is, or was before the rebuild, seeping back into the intake pipe.
Being a transverse version of your engine, the PCV valve is on the front bank and the pipe from it to the intake pipe is quite short. The PCV valve is also situated above (if I remember correctly) a cam lobe so at higher revs, the oil gets flicked up into the PCV valve.
... so use an oil which is thicker at high temperature, do a compression test, or as I'm considering, run the pipe from the PCV valve into a canister to catch the oil before feeding the gasses into the intake manifold. That way less of the thinner oil will be burned off and I'll have a better chance at getting away with using it.
I use 15W40 Oil - viscosity of 15 weight (units?) when hot, 40 in Winter (which the W stands for). I should use 20Wxx, perhaps, to burn less oil.
This engine likes thin oil, it just goes on to liking it enough to inhale it. This engine also likes higher revs.
Hope that helps.
