I'm thinking of using the PAS steering fluid reservoir from the donor sierra. From memory about 2.5" wide by 4" deep by 4" -
5" tall. Has hose connections and a cap that could be used for draining. Is fairly clear so should give an indication of how full it's
getting as well.

1 liter coke bottle is traditional 
Sure I've seen an aluminium water bottle with a K&N breather on the top somewhere on here which was quite classy... click click

I used a cyclists drink bottle complete with nice holder.
Plastic is really cheap, but I decided to go for luxury anodised alloy model, only a few quid with mounting bracket...

or if you wanted something a bit heavier(!) you could possible reuse a emptied throw away welding gas cylinder.

Ive just found an old dry powder extinguisher in the garage. Look to be approx 1.5litres volume. Has a srew in base (i assume for refilling), just
removed it and got most of powder out. Ive taken the handle off the top and can see the plunger. Can seems to be ali. Does this sound useable?
Can i drill 2 inlets in the side and bond in some brake pipe (for eg) with JB weld?? (ive not used JB weld on ali before).
Do i need to remove the spring loaded plunger from the top to fit the breather filter or can this be left as is and the breather filter put in the
side?

2nd pic showing the top. I think i could just leave this in situe and ignore it. Maybe clag some JB weld over it to seal.
Tank is 220 high and 90 dia. To fit in scuttle area ill have to bring vent filter out of side near top.
Any ideas how to incorporate a cheap sight glass? I was thinking of maybe 2 holes, 1 half way other at top and fit small windows but i dont know what
to use / how to fix in.
Im still wondering if JB weld can be used to fix some tubes in?

Normal is getting dressed in clothes that you buy for work and driving through traffic in a
car that you are still paying for - in order to get to the job you need to pay for the clothes
and the car, and the house you leave vacant all day so you can afford to live in it.

mr G, the road and ones drive do indeed make a good catchtank, but i nearly got sent off track last time due to leaving puddles on the garage floor!
I'll use a simple can, and empty it often.

I see now. Well that is my current method. Hence 2 of my most urgent jobs before track day season;
1. Stop bloody modded sump leaking at the gasket,
2. Catch tank.
(3 - timing set up, 4 - suspension set up).
My extinguisher idea doesnt sound too dissimiler to what GMTBH had done with water bottle. iirc he used JG weld.
Pat - how did you do your extuinguisher catch tank?

I made my catch tank drain back into the sump, so no need to drain off when full, or use the road either.
Fit and forget that's what I say.
Cheers

I'm gonna try and do something similar eventually, got an old disposable welding gas bottle and cut and shut to be a little shorter....goona get
some piping and weld two elbows on and use a bit a food pipe to join the two as a sight level....eventually will drain it back to the sump once sorted
thru SVA's etc.....Cheers Oli.
Ps.
How exactly did you unscrew the bit at the bottom and "get most of the powder out?" - guess the garage is full of white powder now!

If your not living life on the edge you're taking up too much room!

I just remembered, I think you are using a single carb in your motor - if this is still the case then you don't need a catch tank at all. You
only need a catch tank if you are using twin 40/45's or bike carbs.
You plumb your crank case vent, from the firetrap into the manifold. the vacuum in the manifold then sucks all the fumes etc out of the crank case and
creates a lower internal pressure in side the crank case and actually reduces the chances of oil leaks.
in order for this to work you need to use a vented filler cap.
Hope this makes sense.
Cheers
Mark

made one from an old extinguisher before, tend to use the big 1 ltr ally beer cans now!
MSA ok as they are 1 ltr and super light!
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

I used an alli thermos flask that we never use. You can see it attached to the back of the engine pictured in my archive.

ive seen a fair few cars using ali drinks containers (like the type you get in Tiscal etc for walking).
John beardmore used one on his minor (see www.beardmorebros.co.uk under his new project).
Do many people pipe it back tot he sump?

Mark (Mookaloid) has just raise a valid point as to wether i actually need a tank or not. My PCV vents to atmosphere (internals are probs not being
opened as no vacuum applied). It has 2 outlets. How should it be connected??
Inlet manifold vac point is blanked off.
Oil filler cap has oultet (i assume this means it is vented). Is it advised to fit a filter onto this (I have one). I observe vapour coming from it -
maybe due to PCV not being connected.
Any comments?
