Crankcases and PCV Valves

How to adjust the Valves on a GY6 engine "A LOT OF PEOPLE DO NOT REALIZE THEY ARE NOT ON T.D.C. AND HAVE THE FLYWHEEL ON THE T INSTEAD OF THE 2nd LINE!" The correct mark on the Flywheel is You will see F and (T) Look under the letter (T) there should be 2 marks The second mark is T.D.C. not the (T). Line that 2nd Line up with the piece of casted thin metal you cannot miss it, Then look at the Cam shaft it should have 3 Holes "The 2 small holes should be lined up perfectly with the cylinder head mating surface of where the valve cover seals to the cylinder head" & "The one big hole on the Cam Shaft Sprocket should be pointing up at a 45 Dagree angle when you look at it while the other 2 are perfectly lined up with the Valve Cover & Head mating Surface" Best Setting for GY6150 vales is 0.03 intake and 0.05 Exhaust.

I believe that you are asking if the Forester engine is what is known as an "interference engine". That is, is it possible for the valves to contact the pistons if they are out of synchronization? My answer is based on empirical evidence from my '96 Outback and my assumption is that these engines are similar in this regard. No, the piston will not contact the valve if the belt breaks. But why take the chance? Change the timing belt because if it fails, the engine ceases working immediately. There are times in every day driving where having the car stop could be deadly. Don't forget to change the water pump at the same time. --Ken

open hood, top left side between valve covers. there is a "funky" plastic housing that turns counter-clockwise (less than 1 inch of travel). then pull straight up to reveal the "missing" pcv vavle. I own a 98 and that's where mine is. by SAR

Its between the lower and upper intake manifolds. It is part of the lower intake manifold and is covered by the upper intake tubing. It's like the surfer riding the ocean with the waves curled over head. In the 3.0 dohc's case the ocean would be the lower intake, where the oil separator rides while the upper intake manifold tubing curls over the top of if. If your lucky you can see just the leading surface with a flash light. The PCV valve is here. Start at the air intake end, look under the intake for a special ford hose assembly; its 3 piece. At the air intake theres a elbow attached to the bottom, its diameter starts at about 1-1/2" and transends to about 5/8" at the plastic or metal formed tube (year dependant). That tube goes down and under the upper manifold where it attaches to a short 2" hose, which in turn connects to the pcv valve. The valve on my 02 is a black plastic piece. It inserts into the oil separator with a quarter turn to the right. It has a square flange about 3/4" back from the valves tube opening. I used a piece of 3/4" sq alumimum tubing (it has and Inner sq of about 5/8") to remove and insert my valve. It you can find a 5/8" 8 point 1/2" socket it will also work. I am told that the rubber elbow I mentioned above is the weak link in this system. It seems that after many hot/cold cycles under the hood that its material weakens and allows the systems vaccuum to collaspe the elbow. I could find this assembly at the dealer only and for a cost of about $32. The motorcraft pcv was $6 or $7. I am told however that the dealer is asking nearly $200 to install the valve. I havent asked them, so I hope this is an urban myth. Good luck.

PCV Valve is right under the alternator. 1. Disconnect the battery. 2. Take the serpentine belt off. 3. Take out two alternotor bolts. 4. Its right in between the 2 heads. Makesure to check the groomet for PCV if hardend remove that too.

it is in one of the valve covers

Too much oil in the crankcase will cause the oil to slosh up into the firing chamber and foul up the spark plugs.

back of the valve cover-passenger side i believe-it has a vacuum line running to the intake.

over pressureized crank case

Try looking on the head, on the passenger side of the throttle body

mine came from the factory without one I had to get the parts and install one ,

but the answer : it is suppose to be at the end of the vac hose on the top of valve cover where the hose goes into the cover I had to buy the grommet and a pcv valve

in what location can I find the pcv valve on my 2002 chevy tahoe

Right corner of the air manifold, you can hear it breath when the car is running.

The PCV valve is in the side of the oil filler housing. It is removed with a quarter turn and pulled out.

Drivers side valve cover towards the rear.

left valve cover toward the rear

Check the owners manual. Its covered in there and I believe has something to do with holding down the trip odometer switch while starting the car. (2000 Odyssey) You don't need to start the engine. Just push in on the trip odometer button and hold it in while you turn the ignition to "ON" (don't start the engine) and wait for about 10 seconds. This will work on 1997-2005 Odysseys. (It may also work with 2006-on but I don't know for sure.)

I'm curious too cause mine needs to be replaced cause my check engine light is on and giving the PCV valve code as well as a "very small emissions leak" code. If I had to guess, it's under the breather that connects to the throttle body. If nobody answers by the end of this weekend I'll have one cause I plan to take care of mine ASAP so I can get my vehicle to pass inspection. Matt

pcv valve wont work properly

It's basically a "plug-and-play" installation. Simply pull the hoses off the ends of the current PCV and replace it with the new PCV. Replacement is reverse of removal.

On the 1992 2.3 it is behind the upper intake manifold, about even with the lower intake manifold (driver's side).This puts it between the manifold and the firewall.

driver side of the front valve cover if its the V6 if its the 4 cyl. its on the top of the valve cover somewhere
