PCV Valve Grommet 1996 5.8L Bronco

[Shep]

Hello. I'm new to the fourm, but need your help. I need to remove and replace the PVC valve grommet located in the right valve cover under the throttle body assy. There is a round plastic union bring the hoses up to the PVC valve. How do you remove the grommet without removing the throttle body assy? Thanks for all of your help. Shep

"By this time after 14 years or so, those PCV valves, hoses and grommtes will most likely fall apart in your hand.

Get all the parts on-hnad before you pull the PCV; reach in and pull.

3speed replaced all and also re-routed the Valve to intake hose assy using;

5/8" silicon heater hose, various fittings from years past and some stainless crimp clamps for plastic tubing.

90 elbow for the valve cover for a Ford (typically found at any auto parts store) and the PCV valve itself from Ford.

3/8" line is typical J30R7 fuel line thats suitable for PCV use.

I wanted to install the PCV valve directly to the valve cover but the intake touched it. The PCV valve was simply too tall. This new setup fits well under the intake with plenty of clearance. Its tight and won't pull out. The upper end is supported by the 3/8" line being tied into an unused OEM threaded location on the intake using a P-clamp.

After installing what I made...I'm much happier with knowing my PCV is secure and sealed tight. Its also easier to get to...although I could have added another inch or so in height making it even easier. But I shouldn't have to mess with it for a long time.

As a side note the valve fits tight into the silicon hose. This type of hose stretches alot and grips well. I really didn't need to use clamps on anything but went ahead and did for long term durability.

Here's the photos of what I made:

Thanks for the detailed information. Do you have to remove the complete throttle assy to remove the PVC grommet? thanks for all of your help.

yo Sorry, I forgot to say NO... it is difficult - I use a foot stool to stand on and lean over..

be very careful to Not lean on the fragile vacuum lines near the Coil on the TAB/TAD sensors, EVR etc. Same forall wiring....

YO,

Removal, Upper Intake Tip & Tool in an 86 5.0; "...This is the Torx T-40 you're going to need to get that pesky inner center ***** out with to remove the EFI's upper intake. Trouble is you'll never get that 3/8" drive socket between the runners, with the space the way it is. I just drift the center part of the T-40 out. It happens to be 1/4" hex. Now it's seperated from it's 3/8" host housing. I use contact cement to glue the T-40 bit into a 1/4" drive 1/4" sized socket and then work with several 1/4" rachet extensions, which pass through the intake runners no trouble at all..."

or repair it as John D did;

The exposed tubing becomes powdery and cracks over the years. I taped over alot of the cracks but it still wasn't good enough.

So I split the ****** taped conduit on my 92 Bronco and began pulling out the tubing. To my surprise, the tubing that inside the plastic tubing was like new. So I cut out the part that was bad back to a couple of inches beyond and used some 7/64" Gas/Vacuum tubing that I bought at my local parts store.

P.S. old model Schrade Old Timer. Real steel blades, cuts better than any razor cutter you can find if you know how to sharpen a knife, find one. You owe it to yourself.....

Anyway back to the story.

So I took my tubing and got some Heat Shrink wrap and went to work. Get shrink that will just fit over the ends and a shorter piece that is 1 size bigger.

Press fit the factory tubing into the new tubing. Press in as much as you can get. Here's about 1/4-1/2" in.

Now with the bigger of the Heat Shrink tubing, apply it over the connection and shrink it.

Now take the other 2 even smaller heat shrinks and slide them over the original connection and shrink those over the first connection.

Resink the tubing back into the conduit and retape to seal it up. Use high temp tape for this as the cheap electrical tape won't hold up very well.
