what hose(vac port) do i use???

below on in this DIY is a hose(vac port) that we use on our car. What hose is it? i have pics of my motor if sum1 could help me in the DIY it doesnt have the pic that should be the since its a oldpost im sure thanks for ur help guys........






"Items Needed:
1 Can of Seafoam
1 Plastic bottle (see through)
1 5/16"x30" tubing (Radiator Overflow tubing is what I used, found at AutoZone or O'Reilly's for ~$3)
10mm Socket and wrench

Directions:
Note: Pictures are high quality, just click on the thumbnails to open in a bigger window.
1. Remove the plastic engine cover with the 10mm Socket and wrench. Place this aside as you will need to re-install it (or leave it off, no harm done)

2. The vehicles engine must be warm, so it is suggested to go for a ride (15-20 minutes) prior to continuing.
3. Turn the vehicle off
4. Remove the tube that goes into the vac port. (Circled with a big red circle in the pic below)


5. Install the 5/16"x30" tubing to this port/nipple.
6. It is necessary to slowly induce the Seafoam into the engine manifold, as such, dropping the other end of the tubing into the can of Seafoam will either suck up all the Seafoam quickly (which is a waste of Seafoam and time) or you will be second guessing how much to induce withing a specified time. To allow for a proper induction and a visual, I poured the Seafoam (entire 16oz can) into a plastic water bottle.
7. Turn the car on.
8. Let the car idle for a minute or two.
9. Slowly insert the other end of the tubing (from step #5) into the water bottle. You will hear it start to suck the seafoam out. It has to be done slowly, so let is suck a little at a time. This is done by barely hovering the tube above the top of the Seafoam (the suction is strong enough to pull it) and then lifting it out of the bottle.
Note: You will start to hear the vehicle stumble and want to die, I merely stopped the Seafoam induction at that point and let the car catch itself, then started the procedure again.

If done properly, the entire process should take ~3-5 minutes for all the Seafoam to be induced.

10. Turn the car off.
11. Pour a half can of Seafoam into the gas tank. (I did this process with about 2 gallons of fuel left in my tank)
12. Wait 15-20 minutes
13. Turn the vehicle on, it won't want to start and might stumble, give it a little gas and it will turn on.
Note: Large amounts of smoke will result, do not panic as this is normal.
14. Go on a 'spirited' ride for about 10-15 minutes. (I merely drove in D3 for 10 minutes. I was doing about 75-80mph on feeder roads by my house, hitting between 4k and 6k RPM)
15. Get some gas."

Ya, the pvc will be kind of dirty, but the way to know if its still good is to shake it and hear if it sounds like a rattle

Yes, that is one you can use. Take the clamp off the hose going into the PVC valve and pour it in there while the engine is running but not to fast, it will stall if you do.

As for if it rattles, then its good is not full proof but I think all the PVC valve is like a small valve inside that opens and closes and usually it gets stuck open or closed when its bad. So if you hear it rattle, that means it still has the ability to open and close.

I mean it's like $10 so if you can find one, just replace it.

you can clean out the PCV with some carb cleaner if its not completely stuck yet.
