help ID'ing some tubes on engine, 01 LSE
Changed the thermostat yesterday, and in the process I managed to break two plastic tubes. I have no idea what the are or what they do. Two very thin rigid (as in brittle) black plastic tubes that run along above the top of the front valve cover. On the left side they connect to two different locations, not sure what exactly (apologies for not being more engine savvy). On the right side they both do a 90 degree turn near the tips and plug into a single hard rubber boot-like thing about fingertip size immediately above the thermostat. I didn't even notice they were broken until I was putting the new thermostat in. I guess I whacked them taking the old one out. I tried using some epoxy to glue them back together but I doubt that'* working. Car seems to be running fine, though, at the moment. They both broke where they go into the little boot, right above the thermostat.
Any idea what these are? I've tried rockauto and gmpartsdirect but no luck finding them.
