I just got my PVC changed on my 91 NA 3.8 and I looked at it and there are two pipes coming off of it. one bigger on closer to the bottom that splits off and then a smaller one that comes out the side of the top. there is nothing hooked up to the smaller one at the top!!! Whats is that for??

The unused port should have a little plastic plug stuffed in it to block it off.

Usually the plug is molded onto the plastic part of the PCV and you just twist it off and stick it on the port you didn't use.
