Guest Minispdrcr Posted November 4, 2013 Share Posted November 4, 2013 I know this is a simple answer. But I just want to make sure I get the correct pieceWhat goes here, of course talking about the hole Link to comment Share on other sites More sharing options...
Guest NikeAjax Posted November 4, 2013 Share Posted November 4, 2013 (edited) A gonkutated-phranistan...DUH! Actually, that's where the snorkel to vent the crank-case goes: it's a tube that goes to the bottom of the car and when the car moves, the oil-vapors are drawn off. I took mine out and replaced it with a PCV (positive crank-case vent, or, pollution control valve).OH, and BTW, that's NOT a stupid question bruddah: a stupid question is more like, "What is Justin Bebier's favorite color..."Jaybird Edited November 4, 2013 by NikeAjax (see edit history) Link to comment Share on other sites More sharing options...

Guest Minispdrcr Posted November 5, 2013 Share Posted November 5, 2013 Awesome! Thanks guys!So what could I out in there to leave it from just being open? Link to comment Share on other sites More sharing options...
bhambulldog Posted November 5, 2013 Share Posted November 5, 2013 It should stay open. Unless you put in a pvc system.The draft tube that is supposed to be there has a goose neck and extends straight down to the bottom of the car, with a bologna cut on the end that draws out the vapors as the car goes down the road (venturi effect)Don't close it off, it's needs to stay open so the vapors in the crankcase can get out.Unless you put in pvc system, then the vapors are sucked into the intake and burned and sent out the tailpipe.

Guest Minispdrcr Posted November 5, 2013 Share Posted November 5, 2013 (edited) So it's ok just sitting open like that on top? Or should I get something like the tube? Another questionHow do the vacuum lines hook up to the bottom of the fuel pump? Edited November 5, 2013 by Minispdrcr (see edit history) Link to comment Share on other sites More sharing options...

Guest Minispdrcr Posted November 5, 2013 Share Posted November 5, 2013 Oh I didn't see your reply Jaybird. I have a 1955. What I meant by the second time is, if it's ok just venting out on top like that or should I try to get a tube that goes to the bottom. Link to comment Share on other sites More sharing options...
Guest NikeAjax Posted November 5, 2013 Share Posted November 5, 2013 Gosh, if you don't know: you don't know... that's why were here, to learn--ask away!What I did was to drill a hole into my air-cleaner, put a brass fitting on that to accept a hose: run that hose to the crank-case-port. You can put a PCV-valve:on the other end, then find something to fill the space between the wall of the port and the valve. It's really pretty simple! Not only does it help with pollutants, it also keeps oil-fumes from wafting around in your engine compartment: once those settle, they collect dirt--FAST!Jaybird Link to comment Share on other sites More sharing options...
Guest NikeAjax Posted November 5, 2013 Share Posted November 5, 2013 (edited) Yes, you could use they snorkel, but go with the PCV-valve: it's much, much cleaner! Those fumes will deposit on the underside of the car--ICK! See the schmootz right above the port, that will be on the bottom of the car, on the tranny muffler, etc!Jaybird Edited November 5, 2013 by NikeAjax (see edit history) Link to comment Share on other sites More sharing options...

Guest Minispdrcr Posted November 5, 2013 Share Posted November 5, 2013 That's what I don't want is the oil fumes in the compartment and making their way into the cab. Thanks you guys!! Link to comment Share on other sites More sharing options...
TexasJohn55 Posted November 5, 2013 Share Posted November 5, 2013 Would you leave your oil fill cap off? Of course not. You can't leave that open hole into the engine either because water, trash, leaves, anything can fall in there. Put the road draft tube on it so the system can work. A PCV system is designed to suck fumes out of the engine , thru the PCV valve and into the intake manifold. When you do that you also have to provide a filtered air inlet to the engine so it doesn't suck in dirt. Normally the filtered air was sourced thru a screen or filter, most were filtered at the air cleaner housing with a small filter clipped in place inside the housing on the prefiltered side of the main element. The road draft tube system used the filler cap to filter the dirty air from entering the engine. That cap has a wire mesh in it. If you convert the system to a PCV, you need to consider that the road draft tube will then become an inlet to the crankcase instead of an outlet and will suck dirt unless modified to filter the air. Just install the road draft tube and be done with it. TJ55 Link to comment Share on other sites More sharing options...
bhambulldog Posted November 6, 2013 Share Posted November 6, 2013 If you put a proper sized grommet in the draft tube hole, you then put the PVC valve there.The air could enter through the mesh in the oil filler cap.That could keep the air flowing in the original direction. And close off the offending hole Link to comment Share on other sites More sharing options...

And close off the offending holeKeen idea! Adjust the idle mixture to compensate. There is only an 1/8" npt port on the intake manifold with a tee for booster and vacuum pump/wiper connection, is that enough and will it affect those accessories? I wonder if you would need another hole in the intake? The PCV has a limited flow and is orificed, I personally think that the road draft tube would be more efficient at venting blowby on an old worn engine under load. If the road draft is closed off, all excess blowby will have to exit thru the filler cap. Just sayin'....... Link to comment Share on other sites More sharing options...

Guest Minispdrcr Posted November 12, 2013 Share Posted November 12, 2013 Well might as well keep up with this thread lolWhen installing the booster. Do you take silver nuts off or put it on like I just have? Link to comment Share on other sites More sharing options...

old-tank Posted November 14, 2013 Share Posted November 14, 2013 The nuts were installed for shipping. Remove and then replace after installation of the unit.The boot shown on your new booster gave me problems: http://forums.aaca.org/f162/55-power-brakes-357520.htmlWillie Link to comment Share on other sites More sharing options...
Guest Minispdrcr Posted November 14, 2013 Share Posted November 14, 2013 Did you just place the holes anywhere? Link to comment Share on other sites More sharing options...
old-tank Posted November 15, 2013 Share Posted November 15, 2013 Did you just place the holes anywhere?Holes would best be at the bottom. I essentially mutilated mine trying to get a previously working unit back to working again and am still looking for a more suitable boot. Check with your rebuilder, or just install and if the brakes stay applied, the chop some holes or replace.Willie Link to comment Share on other sites More sharing options...
