engine breathing and servo vacuum connection Vacuum crank case and servo connection

[AlanL 0]

Cortina Mk1 with early 1600 Kent crossflow  ,  twin choke and single vacuum connection on the inlet manifold 

hi all 

Got my brakes all sorted with new 0.70" master and servo now fitted, 

The engine has the crank case breather can  on the block which was plumbed to  the vacuum take off point on the inlet under the carb, I used this spur for the servo and just fitted a little atmospheric filter on the crank case vent line in the interim.

however I believe the crank case (PCV ?) need vacuum to  operate and I may create ( more)  oil leaks

this may be a stupid question for  the experts, but  this is the advice I need 

Q:- can I simply  "T" piece into the new servo line with the crank case line with 3/8"  T piece and clamp 

there is a sweat around the oil filler cap ( escort type)  so  was thinking of getting the filler cap (Burton) with has the vent spur and plumbing it to  the pancake air filter as well  

 

so  crank case breathing  venting info  required

Just use a T piece in the pipe, some had a T piece fitting in the manifold.

Thank you for getting back to  me 

I've just ordered a T piece so will splice that in !

 

what do  you think about a vented pipe connection for the rocker cover I do  get a mist over the cover, the O ring on the filler cap  is good and no apparent drips from the current filler, just not sure if that would be just a sensible thing to  do  

will try  a latex glove over the filler neck to  see if there is a blow first though

Yes it needs vacuum so the leak is probably caused by the crankcase trying to vent past the cap.

 

It should breathe through the cap but vent through the pipe into manifold & be re burnt, the pre-xflow vented to atmosphere  & had no valve in the can/pipe.

just a follow up 

yes "T" in place servo and crank case vent to  single connection on manifold 

brakes all good and no oil leak or mist on the rocker cover, 

I say " sorted"

thanks for the assistance
