1988 300E, 2006 E350 wagon
this question relates to a 1988 300E: i was just reinstalling the breather tube between the valve cover and the air filter housing. also attached to the breather tube is a small clear/whitish plastic tube that sticks into the bottom. while reinserting this plastic tubing i didn't realize how brittle it was, and well snap! i now have two pieces. so i put them back together with electrical tape and reinserted the tube. can anyone tell me what this tube is for? is it a vacuum line? should i get on the ball and find a replacement for it? so far it doesn't seem to affect the car in any way... if i'm not being clear about this let me know and i'll post pics. thanks.
