ProAlloy Breather Tank- venting to atmosphere

[StreetDragster]

Hi All,

I have the pro alloy breather tank, i see that it vents to atmosphere, and drains down a common pipe, sometimes leaving droppings of oil onthe road/garage.

I don't like this, and want to contain these drops. I don't think i need an 'oil catch can' as i think this is another name for a breather tank.

I'm currently thinking a monster energy can and a few p-clips, but there must be a more elegant solution, preferably with a drain plug and sight glass.

Any ideas?

Matt,

So, your 1 opening does not go to the oil sump?
Did you just plug the sump and remove the return line?

Nope it goes overboard.

I didn't fit it so not sure why its like that, came on the car, but i can't see an obvious stub on the sump that it should be connected to

Fluids should be returning to your sump, there should only be a light mist or vapour exiting the vent pipe to atmosphere.

The pro alloy tank is a separator tank, you shouldn't have to fit another tank for fluids as they should be plumbed to the sump. something doesn't sound quite right.

From posts It seems I have found 3 different ways of what guys have done with the return line.

1) Connect to the sump as stock tank and Pro Alloy tank is set up for.
2) Tank return hose goes to bottom of car/atmosphere instead of back to the sump and plug the sump.
3) Plug return hose coming from the tank and check every so often for build up and plug sump.

It also sounds like most that don't return back to the sump have a short stub of hose coming from the sump like yours and is plugged.
I don't hear of anyone having a direct threaded plug for the sump?

Sorry pat I think you've misunderstood someone's post

The plug is for the standard vent to inlet.

There is only one way to fit the pro alloy tank to allow it to perform it's designed purpose
.
Nobody plugs the return to the sump it's simply a daft idea as the tank is designed to separate oil and vapour, send the oil to the sump and the vapour to the atmosphere. If you plug either hole you simply end up with a blocked tank. Not what it's designed for.

If other people have plugged these returns, they are wrong to do so, I'm sure pro-alloy will tell you the same.

Good to know Graham.
Great to learn so much from the forum.

I am buying a pro alloy hard pipe kit now, how does that get hooked up to the pro alloy breather tank?

The old set up uses the boost pipes to suck the oil vapour from the breather tank back into the engine.

When you fit the pro alloy breather tank you vent to atmosphere, therefor you don't need the vapour to go back into the engine (much cleaner)

So when you get the hard pipe kit, you don't need to connect up anything from the breather tank.

It should all make sense when you put it on

Graham,
Do you have a picture of your tank with hard pipe kit?
This picture of my old one hooked up,next post is the pro alloy hooked up without hard pipe kit.

Here is a picture of pro alloy one installed.
You can't see from picture but all 3 openings are hooked up.

Hummm all this talk is making me doubt my memory of my setup, i'll confirm this weekend.

I also have the hard pipe kit, maybe that is a factor.

I only get maybe 1 or 2 drops of oil on the floor, but i think this is too much

thats it Pat. two pipes come out of the bot, one goes to the sump and vents out the bottom of the car

[patsrocket]

Does everyone have a braided line that runs back to the sump?
I am having a tough time getting it to go on the Pro Alloy tank.
It goes on about half way and it just won't budge anymore?
I'm afraid it may pop off while driving if I leave it clamped on 1/2 way.
Not sure if I am just weak or what?

[2.5bluenob]

ive never seen braided there until now!

Pat, in it's simplest form - the ProAlloy tank fits identically to what you have. The only difference is that your hose with NOBLE written on it in the picture fits to the other bottom port. On your car this hose goes into your front filter pipe. On the PA it goes out the bottom of your car and you plug the hole from whence it came.

[Blu3R]

And to add - I don't know of a UK car with a braided hose, they're all oil spec silicone but still go to the same place.

[patsrocket]

Rob,
That clears it up a bit.

Wonder why PA didn't include an opening in the hard pipe kit to hook up that hose like in the stock application.

Also wonder if my braided line is just a tad smaller ID size than the hose you guys use in the UK and thus it is too tough to get on?
I assume in the U.S.A version they used braided just for extra strength and protection?
It might be best for me to switch that hose out so it fits better on the tank?

[Blu3R]

From memory I think the bottom ports of the PA are different sizes, the smaller 'should' fit your existing braided line (I agree it's probably braided to better resist heat) and the larger port is what you attach your supplied hose to and vent out the bottom. You could vent this back into the inlet as per standard but ideally you don't want to do that, hence the hard pipe doesn't have the facility to connect the breather system to.
On some cars (non Noble) there is another 'catch tank' that connects to the other end of the vent pipe. This then catches the oil mist in the vapour before sending the cleaner vapour out the bottom/back of the car. It has a drain tap to allow it to be emptied at service times. I guess the vent could be routed back into the inlet but again, you're better off (performance-wise not environmentally) not putting an oily mist into your engine if you can vent it out.

[patsrocket]

The hookup All makes sense now.

1 problem I have is I can only get the braided line 1/2 way onto the tank fitting that returns to the sump.
It seems in the U.K everyone uses a rubber hose.
What is the I.D of the hose and any special type I need to go back to the sump?

Thanks for the help!
