Crankcases and PCV Valves

the PCV valve is located on top of the engine, drivers side by the intake.

It is covered in a cylindrical foam material. Unbolt the plastic heat sheild. Pull off thew rubber hose & unscrew the old PCV valve. Replace with new in the reverse.

it is located on the driver side valve cover in the back may be easier to get to from the inside

With reference to the engine manf. tolerances and record sheet, using a calibrated micrometer. Bottom end bearing is removed from crankpin / piston removed. Surface wiped clean. Then at the specified points in the record sheet, measure the diameter. Normally at least 0, 45, 90, 135 deg. with ref to TDC and 5 equal distance locations across the pin.

Normally wear would be seen at the top (highest loaded point), and may require grinding undersize to remove ovality, followed by thorough oil flushing / locate source of contamination.

Check piston rings, skirt and liner condition for wear / abnormalities

Someone just ask this on the Toyota Nation forum. On the 3.0 V6, the PCV valve is on the rear bank valve cover on the passenger side. You can see it and remove it with an end wrench after removing the hose. If the new valve doesn't come with sealant applied a little formed in place sealant on the first few threads.

2 locations possible, either behind the block by oil filter there is a black plastic box, it is connected by a rubber hose, and the other location is the easier one, it could be on the intake manifold between the first and second cylinder channels, just track the black rubber hose( big vaccuum one,most likely running from the front of the intake manifold)! and Google for pics as a pic is worth a 1000 words and also i recommend replacing with a new Honda oem, no aftermarket as they are not engine specific but Honda ones are!

Standing in front of the engine, its on the left side of the engine intake. You'll have to remove that MAP sensor to get to the PCV Valve.

The PCV valve is located behind the alternator, under the intake manifold. The best way I found to get to it is to remove the Passenger front tire, remove the splash guard, Remove the bolts on the power steering hose bracket (just makies it easier to get into the area),remove the oil filter. You should be able to see a hose that runs parallel to the engine block behind and above the alternator. I had to grab it with a plier to get enough leverage to pull it out. Once out, I was able to remove the hose and replace the valve. I put a little oil on the valve exterier to make it slide in easier.

open the hood, reach up and over the intake manifold, the PCV valve is right on the middle of the back valve cover. you should see a short rubber tube that comes out of the middle of the back valve cover and into the intake manifold. the plastic part that is screwed into the middle of the valve cover is the PCV valve..

It's on the back of the intake plenum.

If you still need an answer, to locate the pcv valve you need to remove your air cleaner, disconnect your line going into your fuel filter to get it out of the way and look down directly between your carbuerator and your valve cover. There is a small (3/8" hose, approx 6-7" in length) hose that curves down into the engine and is probably covered with a heat protecting foam sleeve. Slide up the hose clamp and pull the hose out. The pcv valve is stuck inside a rubber grommit in the block itself. You will need some very long and skinny needle nosed pliers to pull it out. Pop the new one in it's place making sure you push it in at the right angle. Replace your hose and air cleaner, fuel filter hoses and you are good to go!!!

A little to the right in the front part of the engine. Buy the part and you will see the the perfect match near the front/right area in your engine, with a small hose on one end.

Its located on the back of the Valve Cover about 4-5 inches from the left side Its located on the back of the Valve Cover about 4-5 inches from the left side.

Positive Crankcase Ventilation Answer 2: The Positive Crankcase Ventilation (PCV) system reduces hydrocarbon emissions by scavenging crankcase vapors. It does this by circulating fresh air from the air cleaner through the crankcase, where it mixes with blow-by gases and is then rerouted through a PCV valve to the intake manifold. - Haynes Repair Manual #36071

most likely on the left valve cover

The brake booster runs to the large port in the rear of the carb or you can tap into one of the intake runners. You may have to T off some vacuum lines as the 600 carb probably won't have enough to run everything. There are fittings that will screw into the large rear port of the carb that have 2, 3, or 4 smaller Ts for running all this. Manifold vacuum will be any port on the carb base plate and intake manifold. You'll need manifold vacuum to the plastic reserve vacuum ball....that's for the HVAC controls. The intake should have a couple of places to install switches into the coolant flow. You will need the ported EGR vacuum switch for your 84 truck. The switch should have two places to hook vacuum up....one you will hook up to manifold vacuum and the other runs to the EGR. There should also be a ported switch to operate the canister purge valve. If your distributor runs a vacuum advance, run that to a ported vacuum port.....anywhere above the base plate of the carb. That should get you started.....as I'm just going by memory.

in the cilinder head cover.

i have a 02 escape and the valve is located on the right front side of the motor (drivers side) but i had to remove the upper intake manifold (big black piece of plastic) and the thorttle body plus the injectors metal bar to be able to reach it. by the way, it's not a metal valve but plastic and has a square plastic form that you can use to turn it. hopefully this help's.

the pcv valve is in the middle of the inside valve cover wich will be called the riht side valve cover

I have a 743 and use Delo 400 15-40 LE (light emissions) For some reason Delo seems to work best in all my diesels. Not sure on the amount of oil for the engine however...

I don't know about the 96', but for the 98' and 2000 it is located on the top of the valve cover on the passenger side near the back. Just pull the hose out and replace the valve on the end. .

The PCV valve is located on the top of the valve cover. To test the PCV valve, start the engine, pull the valve out of the valve cover and put your thumb over the hole in the end. If you hear a little click, then the PCV valve is good. If there is no vacuum at the hole, either the valve is bad or the hose is bad. To see if the hose is bad, pull the hose off and put your thumb over the end. If there is vacuum, replace the PCV valve. If not, replace the hose. It's important to note that PCV valves are sized for specific engine applications. The wrong PCV valve for an application can flow too much or too little air causing driveability problems.

purchase the pcv valve from dealer and get free diagram of its location along with purchase. Usually, you disconnect the whose attached to the valve and pull the valve out.

Check on the intake manifold or rocker arm cover.

If it isn't there check between the alternator and the fuel rail system it is very hard to see and get at. You will have to remove the altanator to get at it . ( at least that is where it is on my 1989 3.3 excuse my rotem spelting

If there are no leaks and your car is smoking out of the exhaust you will need new rings on your piston... but commonly with bad rings comes scored cylinders wich would be a costly fix.

On the v6 its on the front valve to the far left side. You will see a rubber hose which goes into a 90 degree bend into the valve cover, slide that out.. Voila
