the fat one thats pointing toward front of car it goes down through center of intake manifold piping to a black box....

i noticed this line is colapsing!!!

whats this black box and will anything bad happen if i run it colapsed???

 

Black box? Do you mean a black drum looking thing that sits on your firewall and has a clear reservoir attached to it? And what do you mean collapsed?

Some decent grammar wouldnt go astray either...

 

i did alittle research and i think its the pcv breather, a fat vacuum line runs to it....

what kind of issues will i have if the lines colapsing?

its on back of block under intake mani

 

its the crankcase ventilation box... if its sucked shut more then likely u need a pcv valve.

 

What happens when the pcv is bad? Symptoms?

 

rough idle/poor fuel and oil consumption
