Default need help please r.e oil catch can hook up ??

hi guys,
how are ya!
i just brought myself a oil can catch kit.

it comes with two inlet/oulte pipe fittings on top of storage cylider.
im not sure where/what pipes to hook uo where though !
i have a 1991 l98 vette.

still have egr vlave if needed plus i have two small valve cover breathers also to use if needed as well.
now i asked one guy about here and he said keep a breather filter in left hand side valve cover,ok,

then he said run one hose from egr valve to catch can , then on other side of catch can outlet run another pipe back to a t-piece connnected to brake booster pipe which then goes to 8 throttle body intake set up.

is this how it goes and gets set up please ???

or is there another way to do it please ??

can some one please chime in and advise me please !
thanks alot
cheers
shae

Emo - I am having a hard time under standing what you wrote and it confused me (not to hard to do).

If I get the right here is my take -

It has 2 inlets and 2 outlets

are they seperated? 1 in/out for each side to work independently?

hi twisted,
how are ya!
thanks for the reply.
sorry for being confusing here,
ok here goes,
there are two seprate pipes on catch up top of can but no divider plate/wall inside catch can though.
the catch can has two inlets left and right pipe, so the pvc valve connects to one side of the catch can,YES ???
then the other fitting on the catch can connects to manifold ,YES ???
and on the left hand side valve cover you can just run a small breather filter,YES??
now can i hook up the return line air pipe back thru the brake booster hose which then gets connected up too intake manifold,yes ???

hope that clears up a little
cheers

Shae follow these post -

they should shed some light on it if for you.

My belief is you need a can for the pcv - pcv from valve cover to can out of can back to a source of vacuum
and then for your set up a breather would be fine because your using a MAP sensor and not MAF
