Crankcases and PCV Valves

It is located on the passenger side upper-rear of the engine block (I have the V6). There's a black hose going into it. For the years the vehicle was made of 11/2000 and 12/2000 - it is a screw in pcv valve and it is straight. From 1/2001 - 2003 it is the push in rubber/plastic 90 degree bent one. Alot of automotive stores don't ask that - they only ask the engine size, so you end up 90% of the time not getting the right one if you highlander was one in those 2 months (like mine).

The PCV valve is located in the valve cover.

hello, after looking everywhere for the pcv valve i finally found it. if you are facing the tracker from the front it is located just to the right of the throttle body unit (down a few inches) and it plugs in to the top/back of the engine.if you look almost directly above the last spark plug on the right side and you will see where the hose plugs into the block. the hose has a spring clip attached to it and my original PVC valve had a green plastic ring around it with letters written on it. i hope this helps out, i am no mechanic by any stretch so i apologize for the description but it is the best i can come up with.i didn't want to pay an hours labor to replace a $3.00 part!

I have an 01 Chevy 5.3 single cab short bed 4x4. The PCV valve is on the back of the left valve cover.

I have the repair manual in front of me (Haynes), and it says that the Lumina has the PCV valve in the valve cover. Hope this helps? On the 1992 Sable with either the 3.0L or 3.8L it is on the back valve cover (closest to the passenger compartment). It is harder to get to the PCV on the 3.8L engine. The actual PCV is connected to a rubber grommet on the engine valve cover and the other side PCV there is a hose that leads to another part of the engine.

Yes, and it is illegal to drive a car with the converter removed.

I believe that is the electric water pump for the rear heating system.

The PCV is located on the driver's side of the engine. It is at the same level as the spark plugs, in the middle of the engine. It is not seated in the oil cover. It is seated in the oil diverter.

The Geo Metro holds a small volume of oil (4.5 qts) and suffers when down a quart. So maintain oil level is the first solution with some timing adjustment. As well, Increased valve chatter with age is normal, but the in the example of 1.3L 4 cylinder the hydraulic rocker arms (valve lifter, and valve lash adjuster((partsdinousaur.com cheap by experience))) the rollers may break.

The roller of the rocker arm is held by a shear pin that may fail. Remove the valve cover (careful not to over-torque when reinstalling((4ft*lbs)), it will break cover!) and the Spark plugs (compression) and rotate the crank shaft the camshaft will rotate with the crank giving play to the rockers. Being careful not to damage the polish surface you can check that the rollers move freely.

(((( Or ))))

For easier inspection, you can remove the valve cover (careful not to over-torque when reinstalling((4ft*lbs)), it will break cover!) Then unbolt the "Rocker hold down bars" (Two, exhaust and Intake 5 bolts each 25 ft*lbs) and inspect the rollers but finesse is required in reinstalling with weak springs and washers that can fly off in different directions

Also inspect the hydraulic lifters (valve lash adjuster, kind of like a bullet) in the end of the rocker do see if it is dead and does not hold oil with resistance. these can be checked in place and pulled out with pliers (warning may destroy) ((the lash adjuster is a valve with a ball bearing on a spring with a can on the other end that always bleeds pressure. at higher rpm and oil pressure the can is held firmer and further open thereby opening the valves further. if replace remember to prime with oil))

(((Secondly)))

The Piston skirt shattering will cause a "valve chatter noise".

To inspect drain oil, remove oil pan take care with crank position sensor bolt and torques (aluminum plus steel bolts equals stripped threads) . with flash light check piston skirts from underneath. inspect oil pans for the piston rings (unmistakeable) If broken, the piston can be replaced with more difficulty, but if you took off the oil pan it is not impossible. a gently used 88mm piston suzuki 13BBA can be found in a junk yard for fifteen bucks (done on two separate occasions and have two spares) and a imperfect installation without honing and crosshatch surfacing can be accomplished to get you back on the road with little detriment.

And If into perfection a new oil pump to pick-up oil pressure and make the lash adjusters solid to minimize the gap may do the trick.

AND remember to verify your torque specs (Haynes Manual or Chilton)

Yea this ons is hid on top right of engine inside the u shape hose going from the rear of the aluminium air intake ,then routes past the auto matic transmission stick then turns left and connects to the back behind the black plastic air chamber piece. This view is standing in front of car looking back towards the center then right upper side of engine. Hope this helps. Oh by the way the PCV is inside this hose.

The PCV is non-serviceable. It cannot be replaced.

Should be the small black device located on top of the engine, it has two plastic lines going directly into it. If it is damaged it could in fact affect gasoline consumption, however to what extremes I am uncertain.

on the intake manifold.

On a 1978 Nissan 280Z, the PCV valve is located on the under side of the intake manifold. A PCV valve releases pressure from inside the crank case.

no, you should just have to take out the bolts that keep the heads connected to the engine block, it may be sticky trying to take it off because of the gasket but it comes off.

I wonder why you would need that info when you just buy a new pvc valve and replace it.

I

It is right hand thread. Turn counter clockwise to loosen.

hey mate, pcv valve on a vr v6 (not sure about v8) is at the front of the intake manifold just to the left of the alternator and right of the thermostat housing. there's a bolt (i think its like a 17mm or a 19mm or something like that) that you have to undo and wa-la, the pcv valve is right there (you may have to get some long nose pliers to get it out as it gets stuck in there pretty tight)

The PCV valve is located on top of the valve cover in the middle.

Bad PCV Valve.- Your car would vibrate a lot and keep stalling. if you try to floor the pedal in gear, the car will move but, vibration is bad and you'll stall again.

The PCV valve is located on the back side of the intake plenum.. When facing the engine, locate the second intake from your right. Run your hand to the back side of the intake plenum. The PCV valve is screwed into the backside. Start the engine, disconnect the hose from the valve. You should hear the air from the valve. Stick your finger on the hole and you should feel the vacuum on a good valve. If not, replace it.

If the PCV isnt hooked up the car will not run at all because there is no vacuum not true, I forgot to hook my pvc back up and it still ran it just spewed oil

In the back of the engine. You should see two hoses, one big hose and one small hose going into it. You will see that it's treaded. This is to allow you to unscrew it to replace it.

very little, probably had a PCV valve.
