tr3 breather pipe

to the lists, i noticed the breather pipe on my tr3 blows out the residual 
from the motor(which is a normal function), but is there some way i can prevent 
a buildup of the oily substance around the lower firewall and chassis?. if i 
run a hose from the breather pipe to the rear am i changing or harming the 
motor?  happy thinksgiving,  larry schwartz
