i'm putting my motor together, almost done, gotta figure out what these are for... the one on the right looks like oil goes thru it, but i dunno what to hook it to... the other one i dunno what its for... both come out of the intake manifold(1980 manifold, tho the 84 has the same things)

 

the big pipe actually hooks to a rubber hose that is attached to a check valve in the exhaust. like that of a gsl-se. the small one, i have no idea. good question though. i think it may have something to do with emissions.

 

the one on the left is the connects to teh air feed tube on the cat
the on to the right is where the hose for the power assist brakes goes

sweet thanks!

 

I blocked off the one on the left and the one on the right hooks up to the hard line for my brake booster
