Tape for PCV Valve and Evaluation of PCV Hose

Hello all,

behlinla early found that my pcv valve is put out of the base. After the work, I did some careful examination.

Issues found:

1> PCV Valve is very loose. I can easily take it up and push it down.
=> "pcv_Valve_comparison" last image on the second row.
I assume my problem is caused by this.
P0153 (O2 Sensor Circuit Slow Response)

2> PCV Valve is covered full of oil dirty
=> "pcv_front_view" and "pcv_left_side" the second image on the first row and the first image on last row

3> PCV Valve is wrapped with a special gray tape

Question1> Since I will replace the PCV valve myself. I need to find this special gray tape. Does anyone know where I can get it and what the name of the tape is?

Question2> Can someone check my PCV hose end? Do they look fine?
=> pcv_hose_one_end and pcv_hose_two_end third image and fourth image on the first row

Question3> How do I address the layer of oil dirty sit inside the base of pcv valve holder? Is it a big problem?
=> base_of_pcv_valve the first image on the first row.

Question4>Do I need to replace Valve Cover Grommet? If YES, how to remove it from the base?

Thank you very much and Happy weekend

Ha, somebody's been there already with the same problem. The black tape is just electrical tape. Somebody added it to make the fit tighter but obviously that didn't work (it shouldn't have tape on it normally). The oil and dirt is normal, so don't worry about it. Just take a rag or something and wipe it out.

Here's what you need to do. I forget if you said you ordered a new PCV valve or not, but you can do so now if you haven't already. Before you pull the old one off the hose, test fit the new PCV valve in the hole. If it still feels loose, then that rubber grommet it pushes into is bad and needs to be replaced. I don't know if they sell that part anymore, so you might have to get one from a junkyard from another 2000. The rubber grommet should come out with a combination of bending and pulling. Push the outside edge towards the center and pull.

The gap on the hose elbow seems okay, but the one you show in the third picture seems a little excessive. But if it's tight and not leaking then it's fine. If it really bothers you, you can pull it off, add a little oil to the end, then slip the hose back on up to the stop ring.

P.S. The image I posted of the PCV valve was not mine. I found it elsewhere on the site. Credit goes to socrates75.

Dorman sells a replacement grommet at the parts stores in the "HELP" section. I have a replacement on my 87.

Hello Bull Geek,

I have searched Dorman Help section. Unfortunately, I am not able to find it there.

Thank you

I will order one.

Please see attache image on the left.
Question1>When I install the new PCV valve, should I install both P1 and P2 or I just need to install P1. I worry that those plastic will break and am not sure how difficult to pull the P1 out from the P2 on the old valve. Also I didn't find usage for P3.

Question2> I found one here. May you double-check for me whether or not it is the right grommet for PCV valve?

The item description is as follows:
Valve Cover Grommet. 2 required per vehicle (curious why 2?)
Please see the second attached image.

Here is another one from Autozone:

Buy the Motorcraft PCV valve. DO NOT use the Auto Zone universal fit junk. The PCV valve is an IMPORTANT part of the emission system.

I would just replace P1 for now. Not sure where the other two parts go.

Those grommets you found don't look like the correct parts (just based on the pictures). Aftermarket parts info is sometimes sketchy, so I can't tell you if they're the right part or not. If you want you can order them and see.

Thank you for the information.
I will check with local ford dealer and see what they can offer.

I'm also checking out my PCV valve which might have a similar problem (loose). There's a small crack at the end of one of the hoses. Could this be enough to cause a vacuum leak?

Crack in pic won't cause a leak. If hose is hard and brittle or soft and gooey, may be proactive to change it though.
