Oil Filler cap '66 462 open system

Post by action »

Looking to confirm the oil fill cap I have is correct for the application. While I wait for the authenticity manual to come in. If it is I will clean and paint.

This oil filler cap is on my 1966 Lincoln with 462 engine.
The DSO is 15 or New York and I bought the car from a guy in New York.
So the emission control system or crank case is open. (Versus closed)

I looked up the part number and there are three choices.
Chrome cap (Which I thought was interesting)
A cap that has a hose attached to the air cleaner. (Which is for the 66 & 67 closed system)
And a cap for the open system. That part number is B6AZ 6766 A. With that part number there should be a pile of applications.
I looked at the illustrations and there was no picture of the cap off of the oil filler pipe.
The shop manual show nothing either.

I have been told the cap should be black. I am sure this is correct.
Mine is silver and does have a Ford Script Logo on the top. (Hard to see in the pictures. No other markings.

Is this cap correct for my application?
Or is this a service replacement?
Or is the cap not correct for the application at all?

That is the correct cap. It should be either semi-gloss or gloss black.

Agreed. And this is the decal that should be on top.

I’ve been trying to find that decal. I see it available in kits from various usual suspects, but can’t ever find it by itself.

Thanks.

So I will clean it, paint it and then get a decal.

Looks like rubber the right way has it as a single for $9.60.
I may buy a kit since some of the other decals are missing or in less than good shape.

I got my decal kit from LincolnLand way back. I was able to identify a ton of them from Jim Osborne Reproductions, but don’t remember where I was able to select them one by one. Check for a decal catalog online.

I forgot where I got mine, because I was mixing and matching decals from Mustangs and Fords to build what I need for my Mercury Marquis.

I recommend finding a decal vendor that is a distributor for Jim Osborne. They should be able to order anything.

Also check MacsAutoParts.com for decals.

I scan all my decals before I use them so I can make more if I screw up.

Action,

Mine, I believe is original and is identical to the one you posted right down to the "stuffing" sorry, I couldn't help myself it is Thanksgiving time...lol). Mine I believe is semi-gloss black with the decal Dan posted I think I got in a kit either from Bakers or Lincoln Land.

These as some pic I have on this computer. The 1st one is mine from 2008 when were did under the hood and the 2nd one is what it should look like from Car Domain.

I will try to get you some more pics tomorrow with it off the car and the underside.

Thanks the pictures help as a guide. And I appreciate Dan's sourcing experience. I don't have access to something that will re-create a decal. Heck I don't have access to powder coating unless I take the piece to a vendor.

The picture from car domain looks nice with some exceptions the water pump pulley is engine color. I have never seen that before.
Other details is that engine does not have AC and is not a convertible.
And for now that is a distraction. I will get there. The process will be slow for the most part because my '71 has some priority.

My oil filler cap has blue over spray. The engine was re-painted at some point … in the car. The blue that was used seems to be lighter than what is posted above. Which may not be accurate at all.

Without creating drama, is there a place I can go to get correct color?
And I think that color may vary based on engine plant.
I ask because I will buy a decal package. After which I will paint the air cleaner.

One thing I've learned about those open-system oil caps is that you really want to hold onto the original as long as you can. You'll notice that it has a tube in the center with a mesh screen, which is meant to separate oil from any crankcase gases. No replacement cap of any kind, NOS or otherwise, has that tube. And the tube cannot be transferred to a new replacement cap; I know because I tried once.

If the secondary filter element in the cap itself deteriorates with age, it's best to pull out the mesh screen and try to stuff new filtering material into the cap, even if it's slivers of shop-towel. Then clean out the screen (it does need cleaning occasionally, anyway), re-roll, re-insert.

It looks like some one has replaced the mesh.
There is mesh in the longer tube and is fairly course and shiney
There is mesh in the cap as well. However it is older looking and discolored.

I will spray a cleaner inside to clean it out and then repaint the cap top.
I was looking around for a decal kit and Lincoln Land wants $70 for their set.
I stopped looking for decals as I don't need one right now. I do need a few other under hood decals. But that will be a paper chase for later.

I am glad to understand the cap I have is correct. I wonder why it isn't black.

I searched Jim Osbourne reproductions at Dan’s suggestion and came to cjponyparts.com. They’ve got most of the decals individually or as kits. They are for Mustangs, of course, but most are the same. Better prices than other usual suspects too.

How tight or loose are the originals supposed to fit? Mine has no grip at all.

It should be snug. Try pressing it onto the filler tube a bit more.

I took a look at all of the parts books, 1960 - 1972.

First, the B6AZ 6766 A part number was not correct as specified in the 1965/1966 parts book (published in 1966). It was a C6vy 6766-A or C3AZ 6766-A (depending upon the emissions system)

In the next parts book for 1965 - 1972 (published in 1975), the B6... part number is listed as correct, along with a variety of other oddball numbers from a variety of other years and models.

If you go through all the parts books from (1960-1962, 1960-1964, 1965) the B6...part number only comes up for a 1960 Lincoln (was probably correct for all Lincolns 56-60)

So, it looks like in 1975, Ford may have run out of the exact correct boxed and numbered C6... and C3... parts, and simply substituted in other caps that would fit.

So..... If Ford does a later substitution for a part that has run out, is that new numbered part technically authentic? Or, is it simply just a little less authentic than the correct original part?
The problem is that we do not know if these different parts all looked the same but had different numbers on the box, or may have looked different but fit fine and worked for the intended purpose.

Without original boxed NOS parts, we may never know. There is no way to know if the cap on any 66 Lincoln is the correct original cap, a later Ford replacement, or something else. I would say that most caps are probably original, because loss of the oil filler cap is generally unlikely, but over 54 years, things happen.

Thoughts?

More musings in light of the above.

The oil fill cap for a MEL engine or at least my 462 is inserted into a pipe that is on the front of the engine.

In other engines of the period (FE, 385 small block) most are engaged into the valve cover. With tang engagement via a hole in the valve cover. Certainly anything after 1968 would be that way from my memory. Some earlier FE engines had a pipe from the intake or attached to the valve cover. These push on caps with venting on the underside had springs to maintain friction. (See attached picture)

For my 462 the cap has a short pipe that fits into the fill pipe. See above.

I don't have as much experience with pre-64 FLM engines. And it would seem to me that the MEL which began life in the 1950s may have the same cap from start to end. Since it ended life in model year 1968.

Not sure I am going to get an answer and is the cap pictured in the first post at least the correct shape?
Since it is not black, (and never was) I have made up that it is a service replacement. But that is making up stuff which kind of blows the accuracy of what it might be. Painting it black and getting a sticker on top is my intention. As long as the cap has the correct shape and features.
