Mystery Noise From Intake

[TheTroyness]

its the rear pcv valve.. its a valve that moves back and forth fast making that noise.
so remove it or deal with it. like me.

I thought the rear PCV valve was the source of the ticking sound our engines make...

i pinched the hose on the return side of the cc and it stopped, i let it go and it was knocking again. ill check the rear pvc when i put on my dp.. i dont wanna jump in there twice, prolly next week its snowing here... so ill let u know if that fixes the problem.

Bump for update?

if you have a pcv blockoff and still have a rear pcv installed it will do that.

What purpose, if any, does the rear pcv serve if I have a catch can installed?

Are you talking about threads like this?
I've read threads about how to remove the valve, but nothing yet that tells what exactly it does, and why it's there, and why it can be removed. I don't want to just go whimsically break out parts from my engine. At any rate, I've read that the valve causes a pretty constant ticking or putting sound. The sound I posted in my video is by no means constant, nor ticking/putting. However, I also have read a lot that the ticking sound comes from high pressure fuel injectors/compression/cam follower/blah blah blah.
I could only find one thread about getting rid of the valve via search function or Google (key words rear pcv valve). Maybe the others answer my questions, but I can't find them. As far as I can tell, there's only one. Links please?

^ thats exactly it! do that and the noise will go away!
i had the same noise from back in the day, removing the check valve from the rear pcv will fix it.

Alright, I'll give it a shot. I can't imagine how that little valve will make that noise, but I looked at your thread and listened to your video, and it is the same sound (except yours was constant, and mine only happens under certain conditions). I've tried taking that hose off before, and I could never get it off. The rubber hose is on the valve cover HELLA tight. Did you just disconnect the accordian hose and leave the rubber part on, or did you manage to get the rubber part off?
