Question oil puke tank line routing

Hello

I was able to organize a oil puke tank to mount on my 289 USRRC Cobra. Now I'm curios about the line routing.



Where do I need to connect it and how?
- Valve covers (I can see on the picture)
- Transmission (where and how?)
- Oil pan (where and how?)
- ??

Where should it go and how did you connect it?

Please post some picture, which help to better understand it!


Thanks
ALF

Hey Alf, 427's use a hose to the intake manifold, a smaller one to the trans cover, a draft tube to the tunnel and a lower drain tube to the pan. It looks like the 289 picture has the breather to the valve covers and one underneath it heading to the pan? The other side looks like a draft tube up high maybe a tranny one below it?

I looked to see if I had a better picture of that car, I don't. I'd agree that the bottom line looks like it may be heading to the pan? Could be to the intake but that might be a squeeze with the linkage. I've been hoping to see that car again to see some more of the engine compartment details. If I do I'll get some pictures

Exclamation

Hello

Many thanks for your feedback.
I've now the tank in my hands and I'm still trying to find the correct way to connect it!




As I use a 289 T-Pan and a Weber 48IDA intake I'm not sure where and how to connect there.
i.E.. there is no breather on the intake and I don't remember one on the T-Pan.

Appreciate any help (best with picture or drawings). This helps to reduce misunderstandings!

On the 427 A is a draft tube into tunnel, B is back of intake manifold, C is oil pan, D is trans cover, E gets plugged. On original 289 pans it looks like the dipstick is in the motor and the fitting in the side is for a hose barb for the puke tank drain tube http://aviaid.com/shopsite_sc/store/...s_sbf-ss2.html

Default Puke tank connections on a 427

I dont think these puke tanks connect to the valve covers on a 427?

So can anyone list the correct connections? (just got one today )

Maybe lost in translation, and at risk of sounding like a complete arse, what is a 'draft tube'? - just a tube for carrying oil vapor?
also, 'trans cover' - is this a plate on the top of a toploader gearbox?

thanks, Kevin

Google up "road draft tube" - it's a metal tube, usually with a 45* slant tip, that points down towards the road and ends about where the bottom of the oil pan is. All cars used to have these. The idea was that air rushing past the slant tip would create a slight vacuum and pull fumes out of the crankcase... where, of course, they would just dissipate into the atmosphere, never harming nobody.

This is also the reason all roads used to have a black oily line down the center of each lane. Since this wasn't acceptable on race tracks, the puke tank was used to catch (in theory) the liquid oil.

Also: AFAIK, no engines had vents or tubes or breathers on the valve covers until the advent of smog controls in the early 1960s, and performance engines lagged behind road engines. I'd be surprised if any original Cobra engine had them.

er yep, doh! ....not paying attention properly.
still got some questions, i think due to translation probs.....hope you can help...

A is a draft tube into tunnel
- so I run a metal pipe into the tunnel and drop it down at an angle so it drips oil on the road? sure i got this wrong??!!

B is back of intake manifold
OK got that one!

C is oil pan,
D is trans cover,

how do these 2 work- doesnt one go on the differential? or is that the trans cover - thought trans was a US term for gearbox?

E gets plugged. OK got it.

Do you ever need to empty an oil puke tank?

cheers, kevin

A-Draft tube allows vapors (not oil) to escape down into the tunnel. That's why it comes off a top one.
B-Back of manifold, if you need a plate check my site.
C-sump to the Pom
D-trans is the gearbox, I put a little tube welded in to top of trans cover, you could drill and tap for a small hose barb also.
The tube that goes to the oil pan comes off the bottom of the tank draining any yuckies into the pan. That's why we change oil regularly as it also allows condensation into the pan.

I thought only the FEs had a space for the breather plate? SB manifolds have a fitting or need one drilled and tapped. My 289 Performer RPM uses the brass vacuum block for the crankcase vent.

So the puke tank is also the oil fill as well? And has anyone adapted a PCV to this setup? I've seen some where there's just a hole drilled in the valve cover with a rubber grommet.

On the originals the oil fill was a tube through the front right of the intake manifold.
The puke tank collected vapors till they condensed and filled enough to run down into the oil pan. That's why the different levels of tube from the puke tank (draft from top).
It's also the reason for the smooth valve covers........

I find filling it up through this tube is a PITA by the way. With that baffle in the tube, it makes filling it up SLOW. Go too fast and it gets MESSY.

Mickmate - can you post a pick of the oil puke tank installed on a Cobra with an FE?

What's the purpose of this connection? Intuitively it would seem like you just need the puke hose from the back of the manifold and then two tubes going out, one for vapors and one for oil back to the pan. So what's the other one for?

I have a Canton pan to which I would need to add a fitting for the puke tank drain back hose. Where on the pan was the original location? Anyone have a pic? What would be the right size fitting to add? I am actually going to change my oil pan to a road race pan, so now is a good time for me to at least add the fitting and a plug so I can add an oil puke tank later.

It's the breather tube for the trans and the rear end I believe. There's a bump with a vent hole for street cars, comp cars are hooked to the puke tank for the vapors.


I'll post pictures of the 427 one hooked up in the BB forum.

It's a vent for the gearbox. The originals had a hose running from the differential to a "T" on the gearbox, and then on up to the puke tank.

Opinions vary as to whether it's a good idea to connect all 3 together. I omitted the line from the differential to gearbox, but I did connect the gearbox to the puke tank.
