Catch tank questions
I have got three breathers that will need to be connected to a catch tank - two from the heads and one from the crankcase.
Is it ok to chain each of these breathers through tee connectors ending in one breather to the catch tank? It would save some ugly plumbing if this is
possible.
Also, is it better to have the catch tank high or low in relation to the engine?

raz on my pinto i have a breather on the rocker cover and one one the block, ive just got two pipes going into one, with a t -piece and then into one
pipe into the catch tank. i am going to put the tank as low as possible, as the gases condence the then run down into the tank, if the tank was high
they would run back into the block or cam chamber
this is just what im doing, so dont quote me
but sound logical to me

Hi Alex, that is pretty much what I thought, except I wondered if it was better to have the tank high, encouraging any oil in the pipes to go back to
the sump - less emptying of the catch tank too

I am not convinced there is an awlful lot of oil coming out. I have for the time being, got a small can with a small filer on top and put some white
paper around the filter as I could see fumes; so far the paper is spotless, as is the filter so most of the gas seems to be water vapour.
This will condense and you end up with a water/oil mix in the tank so that is not a good mixture to put back into the sump; I also read, probs, on
here, about this happening.

Yep, I can see that there might be some water vapour in the fumes and obviously it is not a good idea to feed these back to the sump. Having said
that, if the tank warms up sufficiently any water vapour will not condense and just carry on through the breather filter to atmosphere - especially if
the pipes are short.
I'll probably just mount the tank where it is out of the way but accessable for emptying.

I bought a cheap kit from nfauto and it came with small catch tank and clear hoses.
I mounted the tank level with the cam cover (k-series).
One pipe from block breather into tank bottom inlet. Top outlet into injection intake. This is basically just cut into the normal breathing
circuit.
The supplied hoses are clear. So far not a drop of oil in tank or hoses
