Reed valve case breather

Interesting...So to achieve any sort of low pressure on the cases you run a breather tank closed to atmosphere ?
It'd need to be fairly rugged construction to avoid collapse.
What's to stop you plumbing the vacuum straight to the case breather ?
In the event of a mechanical disaster, either way of plumbing is going to see a lot of smoke...

next 4 cylinder race motor I do i must have a look at doing this.
 
guy in NZ called Rex Bunn has been selling breather kits for years that are based on exhaust gas scavenging

he has even written a book on the subject, should buy a copy and have a read of it
