A quick xflow breather question
I have read through a load of previous posts and the ways that people advice to plumb up the breather and catch tank system.
The two most popular ways seem to be crankcase to catch can, rocker cover to catch can and a filter on top of the can to let out the vapour, or
crankcase to rocker cover, rocker cover to catch can then again filter to breath.
I am going to opt for the latter of the two but just had a quick question. Instead of putting a filter on the catch can isit oOk to just run a pipe
down beneath the car so the vapour goes down there? This won't in any way be detrimental or cause a siphoning effect?
I have lots of pipe, no filter and I think the outlets on my catch can would be too close together to fit a filter.
Thanks for your help guys.

Go for second set up ,as you suggest, but pop a filter on top of the catch tank - to avoid possability of any oil being deposited on the road.

Ok, if that's the case I will have to buy a filter and put a piece of hose going from the catch can to the filter mounted somewhere. Would have
preferred not to have had to do that but if it's the best way.

Since 1988 my X-Flows and Zetec have all breathed to a bottle, one pipe form the crankcase and one from the rocker/cam cover. The bottle has holes
drilled in the top to allow any vapour to escape. I have never fitted a filter. The only way any oil would get onto the road is if the engine was
breathing so bad it filled to bottle and a filter on the top would not stop that. Keep it simple, forget the filter, its unecessary.

It used to be common practice in the 'old' days for most cars to have the crankcase breather down to the road. In my x-flows and Zetecs in
my single seaters I plug the breather hole in the block and have a breather in the rocker/cam cover., then to a catch tank. Burtons do a core plug to
blank the x-flow off.....
