Evening all,
Continuing with the effort of trying to get my car on the road, I finally managed to get round to filling the coolant up and bleeding the system. This is the first time the car has started properly in over a year so I expected a few things to not go right.
One thing that did concern me however was the smoke coming out of the thing on the rocker cover (forgive the complicated terminology!), is it supposed to do that? I'm sure I've seen it connected to something on other car photos:

Yes the hose should go from your fire trap ( the bit that smokes rising from ) along and to a T piece with the smaller hose going into the bottom of the plenum and the larger going on into the plenum by the throttle opening.
Thus taking engine gases through the system rather than into asmosphere.
Your carb and or air filter base should have something for these pipes to plumb into. Identify your carb then go on a Landrover V8 forum to find out how you should do it.
You can fit an oil catcher so those gases go via pipes to a catch bottle and then a small air vent pipe. Saves putting those gases through again. You need to do some reading up but it's quite simple when you understand it.
Goodluck.

Ahh that makes sense. So I'm assuming it should be something along these lines:

Not sure where the various hoses are going in your picture but yes on similar lines.
The picture seems to indicate that the flame trap is plumbed directly to vacuum at the carb. which is should not be. At the very least there should be a PCV valve in that hose.
Ignore the routing info from the other posters as they are referring to the setup on a fuel injected engine having not spotted the carb. in your video.

Thanks for the help chaps!
I can't find that paperwork right now but from the looks of photos on t'internet it looks like a Holley 4160 sat on top of a Offenhauser 360 manifold.
Only photo I have to hand is this:
Hi Kev, not sure if you'd got to the bottom of this one. I was having a tinker with mine yesterday and had the opportunity to get a couple of pictures.I can't find that paperwork right now but from the looks of photos on t'internet it looks like a Holley 4160 sat on top of a Offenhauser 360 manifold.

It's a bit awkward having the different rocker cover style but the power of presumption would suggest that what Alun and Steve said before is correct and it is indeed the fire trap, mine being the dome-shaped protrusion on the RH rocker cover which is plumbed into the air cleaner assembly as per the below picture. You will have to trust me on that one as the hose route isn't clear from the picture.
Excuse the terrible photography. I was sure I took more pictures inc. disassembled air cleaner but seem to have lost all but this
For reference, mine is running an Edelbrock 1404 carb on an Edelbrock Performer 3.51 intake manifold.
Happy carbing!
.Looks like canoesniffer's rocker covers are swapped around so the flame trap is at the rear.
Yes there will be fumes coming out of it. It is plumbed into the plenum on the injected cars for emission control.
You, could fit a catch tank and plumb the flame trap to it, then vent to atmosphere (via a small K&N style filter) or plumb into a connector in the base of the airfilter - you may have to add a connector to the base.

Thanks for the input.
I've been doing a bit of reading and a lot of people talk about positive and negative pressure within the engine, seems like everyone has a different opinion on it! But upon searching I ran into a post and some chap has done exactly the job with the catch tank:

Is this the kind of setup I should be going for?

Hi Kev.
Can you confirm if there's any metal gauze in the flame trap that smoke/ steam/ condensation is coming from.
It seems like very heavy breathing to me but I'm no expert.
I've recently checked my breather pipe that fits onto that flame trap on my car and it's virtually bone dry of oil or gases.
I've been hoping someone else would mention this rather than me because it might be ok for all I really know but I'm slightly concearned by the amount of smoke coming from that flame trap.
Can anyone confirm if that's acceptable or not. No point going on until you decide if that is going to be a problem.
Regards Al.

I'm assuming worn rings bores or valve seats to produce that level of smoke but until a proper mechanic tells you that then I'm open minded. I can't see why it would be breathing so heavily otherwise. Does you L/h rocker have the small breather attached at the back or is this blocked off.
Oil catchers catch a few fumes and very slowly fills your bottle, that will cause a constant run by the look of it rendering the catcher pointless if you don't resolve the amount of breathing.

Not definatively. You can do, the benifit will be less oil fumes being reburnt and a cleaner running engine.Is this the kind of setup I should be going for?

Factory set up was the flame trap connected direct to the plenum, so that is 'fine' too.
You do need to remember to empty the catch can!
As for the amount of 'smoke'. I'd check with one of the named experts and let them see the vid.
As for the condition of the existing flame trap. Take it off and soak it in petrol or brake cleaner. Or flush it through with carb cleaner. Any solvent will do. If the 'wool' is breaking down or partially missing then knock it out and replace it. A stainless steel scourer pad is a commom replacement. Make sure its packed in securely so it doesn't drop out!
