foreign objects in valve cover

Hello,

I made the mistake of leaving my 1994 Trans Am unattended for quite some time. A resident decided to take up shop in my engine bay. I opened the hood to find grass/plants/berries ect all over my engine. I scared the little bastard away and started cleaning up. Then I noticed the intake vacuum line going to the valve cover was loose. I pulled on it and realized it wasnt plugged in on the valve side and it ate through part of the line. So, now im concerned something got in there. If so, what is the protocol for cleaning it out?
