Pictures of oil relief valve in filter housing.
 

I forget the name of the thread and the user who needed to know so I started this one.
This is what you are supposed to see when you remove the oil filter. Notice the round hole with the circlip.

This picture I have removed the oil relief valve. If your's was missing this is what you will see. Notice the round hole where the circlip used to be.

And this is what the relief valve is made of, laid out in order of installation. First the spring, then the little wafer, then the washer, then the circlip to hold it all in. For those of you who are curious and want to remove yours and see for yourself, it's a PITA to get it all back in and properly secured, aligned in the hole and the circlip all the way down in the groove with the oil dripping down your hand. So proceed with caution if you feel like it.

Thank you EXPONENTIALY for posting those pics Kwik! That is precisely what my problem is.....cannot believe the dealership said those springs came out of the oil filter....they didn't even look!

I'd be driving an "unfiltered" PowerStroke if I took their advice.

This is a great example of the power of an "internet forum"!

Yeah, get the parts necessary and a good circlip tool. I used a 3/8" socket extension to hold the assembly in place while I worked the circlip up into it's groove. The male part of the extension fits perfectly into the hole and the shoulder pushes on the washer. It all wants to jump apart with the spring pressure until you get it securely pushed up into the hole where you can install the circlip. Don't force it you'll break the wafer against the guide ribs in the inside if misaligned. That was the PITA, it kept wanting to go sideways and several times it jumped out on me and I had to go fishing for it across the shop floor.

Kwik, once again you prove how much of a resource you are to this forum.

For me it works both ways. I try and return the help that I get here.

Thanks Kwik! Looks like I need to go to Ford or a parts store and get that wafer. Is that what it is called or is there a more specific name for it? Is it a stealer item or can I get it from Napa? Thanks for you help! Full of useful info as usual. This is the great part about this forum. Stuff like this some of us would never know anything was wrong if it weren't for knowledgable people like you!

Thanks again.

Didn't hear back if there is a more specific name for the " wafer " in the oil relief valve or if it is a dealer only item. Just thought someone on here would have bought one before and knew so I don't get the run around from the parts guys who don't understand. Thanks again.

a safe bet is a ford parts place on the internet, your ford dealer:-X13 , or your local ih dealer:-X22 !!!!
i doubt you will be able to get it from napa.

What would cause that bypass valve to just fall out when you remove the filter? From the looks of it I bet it is a PITA to put back together,, But if mine was to fall out when i removed the filter, I would sure want to know what caused it??? Does the circlip just get weak?

I'm more suspicious of the shoulder that holds the circlip in. It's pretty thin. Either that or the person responsible for the assembly of the oil filter housing was lax it his/her duties and didn't get the circlip seated properly in the first place.
The circlip is WAY stronger than the aluminum that it sits in and I wouldn't be surpised if the lip that holds the circlip in has some damage that allows it to fall out.

Great pics Kwik, my camera and I don't get along so well.

What I use is an Olympus D-580. For the price it works great.

I just went in to Ford to get the parts for the oil relief valve and they tried to sell me the whole bulkhead assembly. ( the part the filter screws onto ) Does anyone know if there is a part number for just the spring, wafer, washer assembly? Or can I make something to work? I have everything except the wafer part. Does the wafer just have to fit the spring and block the hole in the washer and withstand the oil and housing temps? If so I think I can make a replacement piece unless someone has a part number for just the relief valve assy. itself. I searched all the Ford parts sites and the Navistar/ International sites and couldn't find any info on the oil relief valve.

A ball bearing that will fit up into the hole between the aforementioned "ribs" but large enough to not fall through the hole in the washer will work ok. Bear in mind that doing so will raise the bypass pressure becuase the spring is now more compressed. Ball bearing is taller than the wafer. Not necessarily a good thing as it may be high enough to overcome the bypass valve in the oil pump. If you ever truly get a clogged filter some day it would simply cut off the flow of oil to your engine. Very bad thing. So your safest course of action is to get the housing.Perhaps you could find what you need off of a wreck in the junkyard

Thanks, Qwik! Your help is truely appreciated.
