Installed Elite Engineering Catch Can

I just installed the catch can on my 2012 lfx. Is it supposed to be making a little hissing sound out of the can? It sounds more like air coming out.

Yeah, mine has always sounded like it has a vacuum leak. It doesn't because all the fittings are sealed but I assume that's how it's supposed to be.

There’s also a little ticking I can hear while the car is quiet and in idle. Like a feint clock tick.

That could be the direct injection system. It is a distinct "tick" noise.

That ticking noise might be the purge valve.

Direct injection ticking and purge valve ticking are both normal.
