Help and Pics needed: Air Cleaner Housing 258 with power brakes

Hey Guys,

today I finished my brake conversion from a "knocked together YJ booster" setup to original CJ booster.
As the Jeep had non-power brakes originally, I bought an air cleaner assembly from one with power brakes - but it doesn't fit!

It seems that the part which goes on the carburetor is not long enough... or my carb is sitting much to low...
Here are some pics:











Can anyone confirm that this is the appropriate assembly for an 258 with power brakes and the stock Carter carb??

Has anybody got some pictures handy, where I can see how that setup should look like? I've only found some pics with aftermarket carbs...

I know that there is a bracket on top of the valve cover (unfortunately it didn't came with the housing - so I have to fabricate something myself) - but seperate from that something is wrong here...

Any help is highly appreciated...

That looks to be the right one. With all the wiring, vacuum and coolant hosees that criss cross the engine bay it can sometimes be hard to get the base of the housing to sit down where it should. Before I gutted my engine bay I frequently had to wiggle the base into position. Even then I would have to tighten the carb end down first then tighten the valve cover end and just let it sit where it liked. It may not have been 100% correct but at that time all I cared about was making sure both ends had a good seal.

Thank you very much for the picture! That housing definitely looks different than mine... the fitting to the carb is much longer...

I tried messing with the wiring, lines and hoses - but there's no way to get the base housing down far enough...

I will ask the seller of my assembly if he's really sure that this one is off a 258... maybe it's from a 4 cylinder engine???

you are missing the stud and bracket that bolts to the valve cover (sing the 3 holes in a triangle shape) . you need to move the PCV line so that the housing can sit directly on the bracket and valve cover. you also may need to rotate the air intake piece so that it fits nearer the carb and doesn't hit the heater bypass hose.

Got an answer from the seller today. He says it's from a 6 cylinder engine - only the 4 cylinders used to have that longer neck...

So I will try again tomorrow - but I'm quite sure it won't work.

Can anyone confirm that "longer neck" thing? Any thoughts on this?
I'm really confused because every pic I see from a 6 cylinder engine shows that longer neck... so I think that's what I need...

Oh, and if somebody has that mounting bracket lying around and want's to get rid of it...

The neck on mine is maybe an inch and a half long.....if it's longer it's not by much.

The teardrop shaped breather is for the offset of the power brakes as the booster moves it forward next to the carb. The carb neck of the 6cyl is just under 1.5 inches while the 4 cyl version is much longer at about 3 or 4 inches. Also, do you have this black spacer between the carb and manifold?




Next, lets confirm your carb height is correct. Using a flat edge across the top, I get about 5 and 11/16 from the head deck as measured from next to the stud base.





Lastly, the pitch of the braether will also be effected by the valve cover mount. Not only is there this metal base and stud, but a special plastic washer that fits the bottom of the breather.



So check those areas out and tell us what you find.

I opted for a 9" round "open" breather. It requires the 2 1/2" x 5 1/4" adapter, but it fits nicely. Not the stock approach but it works.

Thank you very much for your detailed measurements.

Unfortunately I didn't have time to check yet (the CJ is about 15 mls away from me right now) - I think I'll find some time this weekend...

@EngChase: I have to keep the original air cleaner because of the german emission laws. The CJ wouldn't pass inspection with such an aftermarket air cleaner.

That is a concern. I don't have to pass a test due to age of the vehicle in my area. Good luck, maybe look at PVC pipe to make an extension? Paint it black and try to make it look original.

Just back from the garage. So here are my measurements:


The neck is about 22mm long - that's just under 1 inch. So I am missing about 1/2 inch here...

Next step - carb height:

That seems to be correct. About 145mm - that's 5 and 11/16 inches (I also have that black spacer between carb and manifold).

What I found while looking at the cover was this: (note the green line)

My cover has that "slope" in it. If I look at the first pic from "only in a jeep cj" I don't see that slope...

Then I tried to "simulate" that bracket on the valve cover to see how the air cleaner base fits. I've read somewhere here on the forum that this bracket is about an inch in height. So I took a piece of wood of about the same size.

Here I have a clearance issue with the pulse air hoses...
Can anyone confirm the one inch height of that bracket?

Final measurement for today:

That's exactly one inch. So if the valve cover bracket is also one inch in height, the outer edge of the air cleaner housing would sit at the same height as the valve cover itself... Can that be correct? I bet not...

Did they change the air cleaner assembly for the six cylinder over the years? Maybe it's an assembly for a different year and different carb??

Thank you for your help and best regards from Germany.
