Did you ever get this out? I'm in the same boat with my '96 Bronco 5.8L. I was contemplating pulling off the intake.

I'm getting the same p0171 and p0174 codes. Was thinking air was leaking in through this grommet. It feels lose.

BTW: Kudos for getting that pic!! Tough angle.

 

Bump! Did you ever change the pcv valve? I also have that extremely annoying plastic grommet that prevents me from pulling the pcv valve. I also tried to remove just the pcv valve by loosening the hose clamp. NO-Way, it is melted onto the pcv valve (guess it has never been changed). I thought this was going to be an EZ fix. Yeah right.

 

You might have to pull the upper intake off, especially if your grommet breaks and little pieces drop into the valve cover. It's not that big of a deal and it gives you a chance to re-torque, or replace the valve cover gasket on that side with ease.

 

I too have run into the same problem with the valve cover "cap" on my pcv system. After replacing my pcv I can't seem to get the cap to seat on the valve cover. Has anyone come up with a solution for this issue? Or is it even an issue? BTW I have a 1997 F250 HD with a 5.8.

Thanks

 

If you're talking about the grommet, you might need to oil it up for lubrication or even heat it so it's softer and work it in by pressing, rotating, etc.

 

So, is removing the intake the proper way to replace that grommet? I've been trying to wiggle it around to avoid having to pull the upper intake, but just wanted to double check that it was necessary before doing so..

 

it would help to remove the upper.
