Oil Catch Can? Options

[RolinkHaus]

Wondering if a Oil Catch Can is worth it?

How does it effect the cooling properties? Good possibility I will track the car in the future.

Found some info.

Are there any measurable gains?

[GregAmy]

Catch cans are required by most racing orgs to keep fluids off the track (you don't want to blow vapors to underneath the car, like the old 40s/50s "Highway Draft" systems...)

I've been known to race cars that had a hose off the valve cover stuck into a used oil bottle. Hey, it works...and it meets the regs.

I don't think you'll find that the various systems provide any performance advantage. Their first and foremost task is to safely collect vapors and liquids.

I'm using Tangerine's system on my historics 914. It takes hoses off each head and the oil tower, merges them together, then has a small hose that allows the collectiion to drip back ito another fitting on the oil tower. That way there's no can to empty.

Expect blowback (har de har) on the concept of allowing the vapors and liquid to go back into the engine. Some (like me) say it's harmless, other believe it's the Devil's drink itself that will destroy your engine. And there may be something to that, given I broke my chankshaft in half last year....

So, there's really no performance advantage in it, other than performance on a clean track is better than on an oily track.

If you put the car onto a track

You need an oil pick up
“Tuna can”

The catch can keeps vapors from dripping
The tuna can saves your motor from oil starvation in the corners

[RolinkHaus]

If you were buying a tuna can which one would you buy?

[brant]

I haven't really looked very closely at what is available.

the Weltmeister (old school kit) I don't believe is still available
but I know there is a billet one out now that is pretty affordable
I have not looked to see if CFR sells one

but they are pretty simple
they might be styled differently... but they are mechanically simple to work well

[GregAmy]

If you're putting anything 200TW or stickier on a Type 4 engine, you really need dry sump...

But, if you insist anyway, the tuna can isn't really enough volume for extended g-forces; you really need an extended sump.

I've got two of a different style I'm not likely to use, since the race car has a dry sump. The street car, which may see a TrackNight or two, is on Firehawk A/S tires...

I have a few of the Jonesy tuna cans from the UK on my shelf. I don't advertise them on my website but would be happy to sell one. Best way is to inquire by email.

Mine has an accusump. Agreed not as good as dry sump, but a step in the right direction.

I ran an accusump on a type 4 for around 10 years of wheel to wheel racing
they work fine... I never ran a dry sump -4 to compare to.

the tuna can is cheap and easy for Driver education or autox
I would not be concerned about using a tuna can alone on a track with less than dedicated race tires. Especially for someone just starting out, or Drivers Education type of setting.

the accusump is better on slick race tires and long sweeping corners

I ran a 2nd Oil pressure sender in the front trunk oil cooler system
with the 2nd warning light, you could see the pressure drop well before the factory sender ever warned.

you could easily see when you forgot to open the accusump, and the difference once it was opened.

they tend to blow valve cover gaskets... if you spin or kill the motor and dump too much oil into the block.

Great info as always, Brant!

Mine came with the car and is old. Pre-dates the current ownership of Accusump. It's got an electrically operated valve with a switch on the dash that I've wired to an indicator light. I pre-charge the pneumatic side of the sump to 10psi. At idle I leave the switch off. When I'm on track, engine warm I throw the switch. Theory is if the oil pressure drops below 10 the pneumatic charge pushes oil into the system. I have to remember to switch off while running and above the 10 psi to re-charge the sump with oil before switching off engine. In a spin or a stall it's unlikely that I'd remember...

The newer switch mechanisms have a warning light switch built in that notifies the driver when the sump valve is open. So far mine works so I'll run as is.

Looking for this catch can. Pic posted by Kargeek, not sure he is still active.

[914werke]

I haven't really looked very closely at what is available.

The Weltmeister (old school kit) I don't believe is still available
Its no longer made since Rose Passion bought Automotion & shelved all the Weltmiester line.

but I know there is a billet one out now that is pretty affordable
Correct I have them available listed in the Member Vendor section & I try to bump an add in the FS/WTB Part forum as well (IMG:style_emoticons/default/smile.gif)

I have not looked to see if CFR sells one ? (IMG:style_emoticons/default/confused24.gif)

but they are pretty simple, they might be styled differently... but they are mechanically simple to work well
(IMG:style_emoticons/default/agree.gif)

I still Have a couple of the Welt. Steel version if someone is looking for one. They tend to be in demand when modding for alternate oiling for their ease to tap a scavenge line. (IMG:style_emoticons/default/sunglasses.gif)

Do you have a pic?

[914werke]

Do you have a pic?

Of which the Old Welt. version or the Alum. version I now offer? No matter ~
Here you go:
Weltmiester

New Version

The most obvious difference besides being made of steel is its welded bottom vs the replaceable screen cover like on the OE case.

Yeah, already have one of these. Looking for a oil breather box. Sorry for the confusion.

[GregAmy]

I'd love to find a catch can that completely replaces the oil tower. I have dry sump so don't need oil fill (or dipstick) and it would be nice to just have a tidy box to insert all the hoses directly into it.

Never understood why VW designed that oil/breather tower that way, and with that method of attachement to the case. I'm sure there's a historical reason for it, but it just don't make no sense...

I may have to design something and ask Foley The Wizard to fab it up. Use the same cork gasket (can't think of any other way) but provide all the inbound fittings, and secure it to the case with plates threaded into the holes where there clip currently goes into. Or something like that.
