I took a look at my B16 swap yesterday, on the IM I have a broken vacume tube splitter, and the one on the trottle body. Now ive searched around and cant find anything on what these do. I have asked a few people and they said its all for emissions and that I can just put a block off plate where the IM one broke off. What my question is will this affect the engine at all?

 

Got a bigger picture?

 

the one on the left t's with the tube from your valve cover to your intake and im not sure what the other one is, ive heard one of them is for a/c but i doubt it, probably both emission, i dont even have the one on the right and my car runs great

vacume ======vacuum

 

Thanks for the help. Guess I'll find out in a few days when the engine is put in.

 

no they dont do much. all the later versions had them removed, they are also on 90-91 integra's too.
