Oil Breather Pipes

[Phil205 1 1 Cars]

Why does the 205 have 2 oil breather pipes ?

 

The larger one goes from the oil filler cap to a point betwen the AFM and throttle.

 

The smaller one goes from the oil filler cap in to the throttle body.

 

Why 2 pipes and what do they do ?

Good question

from what i can gather,

the smaller one has a higher vacuum for pulling condensates from the oil system, stopping water from returning to the oil, and the larger one is lower vac, but greater flow for vapour removal..
