air filter

[smurfette]

can anyone tell me if the stock oil bath air filter assembly can be converted to use a regular air filter??? this is my first experience with this type of filter and would like to put a regular filter on instead...

Smurfette..,

Now that's interesting....in that most folks don't know what an "oil-bath" air filter is....

Long/short., truth told., that's the best automotive air filter ever designed/made. (I still have mine & wouldn't part with it) [-X

If yours needs some slight repair & the fibers are in good shape...clean it up & use it.

The reason it was phased out is because there was no $$$ to be made for replacment filters.

I clean mine a couple times a year & use automatic transmission fluid but motor oil works fine.

ALSO., it's tricky fitting a filter large enough to clear the hood,but doable. (assuming you have the stock carb.)

Lastly.., these days, they make mega $$$ filters that you "soak-in-oil" ..!

And yah., they claim all this improved performance & HP...!!!!

If ya believe that., there's a bridge there in NY I'll sell ya..... :lol:

OOPS., I forgot..., I have seen pics of this filter "jerry-rigged" with a fiber filter somehow attached to the bottom, in place of the oil section.

How well it worked, or sealed, I haven't a clue.

HTH

OK, that does help alot.... how much of it comes apart and what is the best way to clean it??? I'm not sure the carb is original, it is a 2bbl, but the fuel filter/line enters on the passenger side, most I've seen in pictures enter from the front .... the stock filter came with it and does fit though...

 

[Bully Bob]

If you get a chance., post some pics of your rig so as to help us help you....

It does sound like a carb swap happened at some time.

Basically., there's a tube of sorts that runs fr. the carb over to the filter. There should be a wing-nut., or nut of sorts on top that holds the filter up in place. Then usually, there's a nut on the bottom that allows the canister to seperate. After seperation, you'll see the perferated metal holding the oily fibers. The bottom of the canister holds the oil. once it's poured out., you should see some dirt (like mud) in the bottom. Wipe & wash that all out. (best to use rubber gloves)

You could use spray carb cleaner on the fibers if they show anything other than oil on them....& let drip dry.

Once the canister & fiber part is clean ....from then on, it's self cleaning (the fiber part) & all you need do fr. then on is pour out the oil & wipe out the bottom, & replace oil.

Should yours (the fibers) be clean & just oily....meaning someone has serviced it not to long ago.... then you can get by with just letting it drain a bit & wipe it clean.

With the canister bottom clean.., you'll see the "fill to" line marked inside.

BTW., the way this works is; with eng. running, the air is pulled thru the oil at the bottom, & the oil migrates up the fibers...these oily fibers catch the dirt & when the eng is stopped the oil & dirt drain down into the bottom of the canister. The dirt settles to the bottom (mud..!)

Hope that's clear as "mud"... /emoticons/[email protected] 2x" width="20" height="20" />

Cool, makes sense... I'll be cleaning that up tonite. I'll try to get some pics posted this weekend. Thanks again for all the help!!! /emoticons/[email protected] 2x" width="20" height="20" />

Follow-up..,

The books says 1 pint of SAE 20wt. below 32deg. (30wt. above 32deg.)

FYI & BTW ....should you choose to eliminate the oil bath....there's prob. several folks who have the stock EB filter set-up with dry filter laying around.

OR.., you could prob. find one in a wrecking yard.

OR.., there's aftermarket filters out there., but you have to be sure it clears the throttle linkage as well as the hood.

oil baths are cool and bitchen on stock rigs but if you tip your rig more then 45 degrees I would go with a modern air filter unless u like too push smoke for fun.

I have a chrome local parts store drop filter that clears all linkage 29.99 type gig

[Bully Bob]

Hay BBB.., How's things down in SC...? :-B

".....if you tip your rig more then 45 degrees....."

Not going to happen...there's about 1" of oil in a 4" deep bowl.(& a lot of that oil is up in the fibers) [-(

One would have to "flop over" nearly 90deg. to get the oil to flow.

UNLESS.., someone un-knowingly filled the canister full....

 

[S_bolt19]

I'm just curious, because I have never seen an oil bath on a V8 before, how this is mounted on yours. Every EB I have ever seen that had either the 289 or the 302 always had the paper air filter. Both the 68 and the 70 that I used to own had the paper filter. The only oil bath I ever saw was the earlier inline engines that had them. Like BB said, they really are the best filters out there, but economics (for the filter companies) dictates that they are no longer in production. I'd like to see a picture of your setup if you can post it up.

How do Bully?

I was guessing on the tip and oil going down the carb thing, from what

I saw in my 64 Volkswagon days. I quess I dont know a thing about bronco oil bath filters.

I bronco has only seen a few trip this year, the other rig is used more because we sleep in the back and and it has ac!

Still camping and wheelin in the San Berdu Mounts and one trip too Pismo Dunes. Would like too get rid of one toy(65 mustang) and trade into a Cab over camper, so I can camp and tow one other toy(bronco or boat)!

Hi Sbolt...,

I think we scared smurfette off ask'n for pics.... /emoticons/[email protected] 2x" width="20" height="20" /> /emoticons/[email protected] 2x" width="20" height="20" />

Anyhooooo.., The oil-baths were fr. '66 - '70 Another reason they fazed out was the smog junk req. to be attached to the filter housing. (I believe they disappeared in Cal. first)

To my knowledge, they didn't look much diff. fr. the side mount element filter we've all seen.

 

[S_bolt19]

Where's it hang? I am gonna assume that it is a realitvly small unit that hangs over the pass side...correct in my guess? Like I said, the only ones I have seen are the 6-banger ones, so I am just curious how they mounted them. Like I said, both my 68 & 70 had stock air cleaners & they were the blue metal bodies with the paper filter inside that hung over the pass side too.

 

[Bully Bob]

Now ya went & forced me to look it up....!! /emoticons/[email protected] 2x" width="20" height="20" />

As I suspected., the dry element was an option...that's why they're scattered country wide...

Size wise about the same...(my oil tub is 10" wide)

They would hang in the same location (pass. side)....& most folks wouldn't know the diff. until they took it apart.

P.S. the I-6 hung them on the dr. side "FWIW"

 

[smurfette]

hey guys, you didn't scare me off... been really sick( sinus inf.) and having more problems with the Bronco... It has an aftermarket Holley carb on it and it runs like crap. I'd like to put the original autolite 2100 back on, but haven't been able to locate one yet... I'll try to post some pics this week . sorry its taking so long.

 

[Bully Bob]

Wellll...,

Take a good look at the linkage.... i.e. be sure they didn't "cob" it up with the swap. That would make a prob. for re-installing the stock carb.

The 2100 is a good unit...but would prob. have to be re-built B/4 installation....if it's not already been serviced.

You could try having someone fimilar with Holleys just open it up, insp./clean/clear any problems.....This could be a bit cheaper & get it runn'n while you attend to other things. (this is a good carb. as well)

Having said that., be sure it's, in fact, the carb. acting up & not something in the ignition, timing, or general eng. condition B/4 going after the carb.

Good you're feel'n better....... /

 

[S_bolt19]

Swapping out that Holley will help you a lot. Unless it's dialed in correctly, accurately & such, holleys run like ***** not to mention, I don't like them on EBs. I had one on at one point & I went back to the original carb. Best thing I ever did (when I was still a carb'd engine)

 

[smurfette]

The Holley on it is set up for race, so mid throttle it stumbles alot.... i may have found a 2100 carb, my brother is going to rebuild it for me, maybe put it together tomorrow. Hope its better. we did check to make sure the problem is in the carb, new plugs,wires, cap & rotor,ignition timing is set at 10 degrees btdc. I'll keep you posted how it goes, and i promise to get some pics too!!

 

[Bully Bob]

Is that a 2brl. or 4brl Holley.?

There's not much one can do to a carb to make it for "race"

Did you try backing the timing down to about 7deg.?

And/or remove the vac. advance hose.

Just sounds more like a timing issue...maybe test for timing chain slop as well.

--- BTW--- How did the oil-bath clean up go...?

Any additional carb stuff., may be best to start a new thread so as to get more folks input.. /

 

[smurfette]

Its a 2bbl, 500 cfm I guess I used the worng description... its more like it surging when just a bit on the gas, but when you floor it, it runs great! from what I've read about ht carb, its designed for circle track use so maybe its jetted too much, not sure. My main goal right now is to get it running well enought to take it to a big car show here in NY in a couple weeks. I have taken my Mustang to it several years now, but really wanted to take the Bronco this year. We did try to set the timing at 6-7 edgrees, but it ran worse, maybe with the other carb we'll have to adjust it again... we'll see how it goes tomorrow night. I'll post a new topic then... btw, the air filter cleaned up nice, thanks for all the help too /emoticons/[email protected] 2x" width="20" height="20" />
