ok.. the car will hopefully be finished tommorrow.. i was wondering.. do i need an oil catch can setup? currenly i have no line running from my intake to my valve cover.. i was just gonna stick a breather on it... but a friend said i needed the vacume line from intake to valve cover... i was thinking about it... wouldnt that pressurize the crankcase under boost? there isnt a 1 way valve in there.. so how would that help? let me know if im seeing this wrong.. and the right way to set it up

 

anyone?? hoping to get all this straightened out today and get the car running

 

There's a Forced Induction forum.

But yes, when boosting you want a catch can setup. You're going to be having some blowby.

 

Do a search for username dasher in the FI forum.

About your valve cover I dont know if you mean connect it to the charge piping or the pre compressor intake. You definately dont want to hook it up to the pressurized charge piping. You should be able to hook it up to the pre compressor intake, but it might be even better to hook it up to the catchcan.

I'm gonna run a -10 AN line to the two ports on the back of my B18C and those will go to a catch can. My rear valve cover nipple will probably get T'd into one of those lines. I will also have a -10 AN bung welded to the front of my valve cover and I'm gonna run another catch can for that.
