Elite Catch Can

Joppy818 · May 11, 2016

I just installed an elite can on 6.2 sierra. I have noticed a slight hissing sound. Not sure where its coming from. Searched onother forums this is semi normal. Is that true?

No hiss here! I have the Elite Ultra, and its huge! I put PTFE tape on all my joints.

I did not use the 1 way valve, 1 did have a hiss or weird noise when I checked it out of the system, N/A engine leave it out, if FI then use one.

Just make sure all your connections are tight. Do you have clamps on the barbs on intake manifold, and the one under the throttle body?

Did you also do a clean side separator?

I have a slight hissing from the RX catch can on my Camaro and its been that way for over a year. It is working fine and zero issues.

Mine hisses as well, not from the hoses or fittings. Best I can tell is the noise is coming from within the can itself. Sent a video to Elite questioning the noise and they said they would try and reproduce the noise at their shop but I never heard back form them after that.

It can't be heard outside the truck, only with the hood open and ear near the can. Otherwise seams to be working properly.

Actually im happy to have it installed i can deal with it. It is ever so slight anyway. From what i have been told is perfectly normal. Considering i removed a 6 inch between the pcv valves and replaced with over three feet of hose and a can seems fine. More hose does this creat more vacum. Maybe thats what i am hearing??
