x flow breather excessive smoke
Have fitted twin 40s and now have an issue with the smoke/fumes from the breather.
Have removed the valve from the block breather as I have excessive smoke through the oil filler cap. Where should the block breather go now?
Could this be an indication that the engine is on the way out?
Thanks

did it go to the manifold originally ?? if so drill and tap the manifold and feed it back into the inlet tract or fit an oiu catch tank. Sound like
you've got a bit of crankcase pressure, engine will probably have miled in it yet as they are a tough little unit. a bottom end rebuild should
sort it out if it gets too bad. Keep your eye on the oil level and pressure

Well, if they can stop the reek in the engine bay I could be interested. Would a catch tank stop the smoke/fumes getting out?

We had exactly the same problem when we fitted bike carbs to our crossflow.
It's cured now, no heavy breathing or smoke and more power to boot. We fitted a Zetec  but got enough cash for the worn out crossflow on eBay
to pay for the conversion

is it smoke or steam?
easy way to tell is to put a piece of paper near then see if the paper is stained (oil) or remains white (water).
I have a fair bit of steam on mine that I initially though was oil.
The pipe should go to a catch tank, with a breather.

My engine did that before I rebuilt it . I did find dropping the oil level almost to the minimum on the dipstick tended to reduce the fumes
