Crankcases and PCV Valves

on the back of the engine under the EGR valve and the hose can easily be traced from the pass side of the intake mannifold back to the pcv

next to left side diverter valve right under it. Its a y hose and the pcv valve is under a rubber cover.

If the vehicle is subject to nothing more than just short trips, then this would be normal. It would also cause accelerated engine wear due to corrosion. What you are seeing is condensation mixed with some of the oil/residues inside the engine. Remove the oil cap, and the underside should be just covered with the same. Take the car for a run of about ten miles, and check the condition again, while the engine is still warm. If the condition remains the same, you may have bad intake, or head gasket(s).

I have never worked on a 1998 Civic but I have worked on a lot of Hondas. I have worked on 88,90,91,92,93 and a 95 Civics. the pcv are right under intakes.

model?? engine?? pcv is usually located on the intake and is threaded in. generally they are metal.

where is the pcv valve located on a 2001 buick lesabre

Your PCV valve is located on the valve cover. It should consist of a grommet on top of your valve cover. The PCV sits on top of the valve cover and the top portion has a rubber hose which leads away from it. Remove the rubber hose from the top of the PCV valve and then remove the PCV valve itself. Replace the new one the same way as you took the old one off. it is behind the intake manifold, PITA! ---------------------------------------------------------------------------------------------------------

== == You can access to the PCV value by either removing power steering and the PCV value breather, or by removing the Intake Manifold Air Control. I did the latter.

1) Remove the oil filter, no need to drain the oil, but you will lose a little bit.

2) Remove the oil filter base. Four bolts. A flex head ratchet works best.

3) Remove the IMAC, just four 10 mm bolts. Besides the socket, you'd better has a 1/4 ratchet, and a wobble extension bar to remove the upper 2 bolts from the hood area. Then you can remove the two lower ones from below.

4) Disconnect the two small hoses and one big hose. Keep in mind, the two small hoses are filled with coolant. So wear a safety glass and find two clips to stop the coolant when the hoses are off.

5) After all the pain in the ass, now you finally can access the PCV value. A subby ratcheting 19 mm wrench works best here for the PCV value.

Installation is the reverse. Mine still rattles well after 160 K, although it is kind of oily dirty inside.

Very hard to replace for a "do it yourself project". Hard to reach and plan at least 4 - 6 hours to replace a $1.50 part. Cost at the dealership was $175.00 labor to replace the PCV valve. However, the car does run much better.

The PCV value on a 2003 Dodge Durango is on the side of the oil fill shaft.

No, inside a pcv valve is a spring that might loose it's correct rating, also there are seals that can be ruined, not worth bothering, just replace it

No, some rattle is normal.

That depends on the mower and engine. I have Cub Cadet rider with a 16 hp Kohler engine that does call for 10w30. A lot of others call for sae 30 only.

Behind the intake plenum.

The PCV valve on these engines has a metal body with a rubber seal

around it. This seal actually locks the valve into a raised plastic fitting

on the rear valve cover. Problem with removing is due to the rubber

seal hardening. I removed the wiper module to gain access but do

not recommend this unless you have some mechanical ability. It is

necessary, if rubber seal has hardened, to grasp the tip of the valve

with vise grips or other locking pliers and then use a large screw

driver to pry up on the vise grips. Put something solid on top of

the intake plenum to use as a fulcrum. The rubber seal will probably

break in half so be sure to remove the broken part from the

raised plastic fitting before installing the new valve. The PCV hose

will also be hardened but can be removed by removing the plenum

end first and then twisting/lifting on the end attached to the

valve cover.

Under the "sight shield," the plastic engine cover. Remove the two black 13mm nuts, then unhook from the clip on the rear valve cover. The PCV valve is located in the front valve cover, on the transmission end of the motor, opposite the oil filler cap.

yes

On the valve cover (drivers side) back towards the fire wall. you will see a black airline hose, connected to it.

You should be able to see a hose from the throttle body to the rocker cover. The hose may be big enough to completely cover the PCV valve so you might not be able to see it. Pull the hose out of the rubber grommet in the rocker cover. You should be able to see the PCV valve once you pull it from the rocker cover.

It is located on the back side of the upper intake plenum under the cowl.

Not sure if 1995 is like 1994, but on my 1994 MPV 6cyl (3.0L), the PCV is in the middle of a hose on the BACK of the engine, UNDER the throttle body assembly. Took me a LONG time to find it!

Normally mounted on the intake manifold somewhere, usually near the rear of the engine, but it depends on what engine you have of course.

I was told the same thing....There IS a pcv valve and it can only be purchased from the dealer. Go to the normal spot for a pcv valve (passenger side valve cover near the firewall) There will be a hose connected there, follow that hose to where it connects at the other end. That is the pcv valve. it also has two smaller coolant lines attached and is held in with two screws.

Use exactly what the engine manufacturer recommends.

Remove the vacuum hose from your 1989 Oldsmobile 3.8 liter engine PCV valve. Remove the retaining bolts from the valve. Reverse the process to install the new PCV valve.

the hose that is connect to your engine.
