Default Help Name This Part!?

I'm ordering an oil pan baffel overnight from summit and I'd like to get this replaced also. It broke while removing. It was on the passanger side of the intake with some hoses connected to it. I believe it may be part of the evap system. If so can I just delete it? I could not find it in my FSM. What is this called? Part number anyone?





Thanks

Looks like the one way vacuum check valve for the A/C and cruise, should be PN 15733271

Hi Rick, can't name it, but I had to replace an elbow piece that connects to it, and I'm not at home to view my FSM (85). Mine looks a little different, but it does the same as yours. It helps to operate the temp control on your AC/heat, by vacuum I'm pretty sure. You most likely don't want to delete it, as it may mess up how your engine runs aside from messin' with your cold/hot inside the vehicle. If i'm wrong, someone has got ya covered, or I'll check back later when I'm at home...

this is a very common 2 port check valve that you can also get at Pep Boys or Autozone
