2006 cobalt check valve

[haroldlwason]

I bought a 2006 cobalt ls with a 2.2 with a bad engine. I found a good engine with low miles for a good price but It doesnt have a place for the check valve on the back of the engine. My question is I live in Nc we have inspections where if you have a check engine light you cant license the car. Now my question is If I install this new engine without the check valve my check engine light will be on. Is that correct?
