PCV Valve Elbow

It's usually a 5-minute job to replace a PCV valve. However, this time, I can't figure how to get that 90 degree elbow off the valve. It looks like it is heat shrunk onto the valve.

Thanks






Have a big Mustang day!

No. Apparently, we are not.
That part in the picture isn't the PCV valve. It connects to a hose that is connected to the air intake upstream of the Throttle Body correct?
On the opposite valve cover, there should be the PCV valve and the hose that it is connected to should be attached somewhere downstream of the Throttle Body, on the plenum or the intake manifold.

Ok. Isn't the PCV valve on the passenger side valve cover (SOHC)?

This piece came off the passenger side valve cover.

Thanks.

that is the pcv valve. the drivers side one is just a vent. not rattling piece in it. i take it you bought a new one, and it did not have a 90 degree angle on it? i just left it on the old one and stuck the hose straight on it. maybe a motorcraft one will have the 90 degree piece on it, but the autoparts store brand did not.

Thanks.

This item I bought is the Motorcraft part. It does not have the elbow. The tube isn't long enough to connect to it without the elbow.

I guess it is almost impossible to remove the elbow?

Here is what the PCV valve looks like on my Bullitt. It is just a standard valve that they have been using for 35+ years.
My car is different than the GT's and I think that everything is on the opposite side as the GT's. My PCV is on the passenger side valve cover.
Perhaps the PCV valve is completely different on the GT's? I've never seen one with threads and an o-ring like that one pictured.

Did see some research. All of the 2V PCV's are on the passenger side. It's the 4V that is on the drivers side.
Regardless, that is the damndest looking valve that I have ever seen.
The elbow on the valve that I showed, will pull right off. Try putting your PCV valve in some hot water to soften up the plastic and then give it a good tug.

PCV Valve Elbow

That sounds like a good idea. If it works, I'll quickly put the elbow on the new valve.

Theres 2 part numbers for the pcv valve, but I havent seen pictures of each one. I assumed one is like mine, straight piece, and maybe the other is a 90 degree. Both fit, just a matter of making the hose fit. I remember mine being a bit tough but I cant remember how I made it work.

The PCV valve is actually different on my two Bullitts. The one in the picture is a standard valve. The PCV valve on my other car is a heated valve. It has a coolant line that wraps around the valve, heating it. I don't know the purpose of that but it may have something to do with CA emissions. It still just pops into the grommet like most of them.
I looked at the PCV on a Grand Marquis that I have and that one is the straight up style without the 90 degree elbow. It also just pops into the grommet on the valve cover... No threads.

Straybullett,
Your picture shows the same elbow as on my GT. How hard is it to take the elbow off the PCV valve?

Thanks

The elbow pulled right off of that valve.

After heating the elbow/PCV valve in a very hot water bath, I still can't separate the two. I'll just get another elbow to finish the job.

FYI: the Motorcraft part I purchased is EV-257 and it does not include the elbow.

Thanks for the help!

That damned PCV valve had me curious so I did a little more research and they did change the design on the later cars.
I'm guessing that your car is a 02-04.

Looking at Rockauto, it seems like all of the non-heated Motorcraft PCV's come with the elbow included. Maybe it is just missing from the box?

Mine is a 2002.

Here is the bag. Maybe, this item came from an older manufacturing lot before they included the elbow.

Does that piece rattle when you shake it? The passenger side rattles, the driver side is just a straight through piece.

But ev257 sounds familiar like the right part

Yes. It rattles.

It actually rattles better after soaking it in hot water for about 15 minutes.
