Subject: Got my new INDY intake today,no place for fill tube or pcv
To: AMClist <mail@xxxxxxxxxxxx>,

Well, my new INDY intake arrived today.Looks pretty
nice...except there is no way to add an oil fill tube
or a pcv valve.NO provision to drill/mill..etc. Guess
i'll mill my Payton style tall finned aluminum valve
covers for breathers. 

Has ANYONE ran the crankcase
evacuator setup on a "mostly street/some strip" car
with success? 

OR..should i just put a pcv in one valve
cover/a breather in the other? Suggestions??? Any
certain pan evacuator  setup better than another? Post
and also Email me directly also if you would. Thanks,Joe

What I learned from the BMW motorcycle race Grp.
for their Daytona Race Flat Twin bikes to control
crankcase pressures - as the  case itself looks like a
narrow suitcase:

At the top of the engine is a 'flapper' valve >
phenolic disc that slides on a post with a small
spring to keep it tensioned > allowed crankcase
pressure out > prevented the 'inhale' somewhat.

A large diameter tube then ran to a 'breather box' >
which had some baffeling added inside > sorta like
the insides of a Turbo Muffler > to allow dropletts
to collect.

On the far side of the box were a rack of Two Stroke
Reed Valves > I think from a Snow Mobile or a Yamaha
roadrace bike > which let the pressure out but blocked
the inhale.

These reed valves were then enclosed in a 'box' with
a hose attached which  led down to the exhaust pipe
that kept a mild suction to the reed valve box as well
as a place for the 'blow-by' to exit rather than to 
the ground & rear wheel of the Race Bike.

I've seen similar construction for automotive apps.

I'd leave the 'Breather' in place and start your run to
the 'Breather Box' from there.


Hope this helps !
