What is the correct information then? I was told by a professional tuner (Funtion: Tuned) that I needed a catch can. It never caught anything in 1.5 yrs but I still feel like I need to replace it because I damaged it. Now, my PCV line is just chillin in my engine bay and I have it pointing towards the ground.

 

Just get the parts necessary to put it back in the stock configuration. Running it with the PCV system disconnected is bad for the engine.

 

I had a Greddy catch installed in my 07. I took it out because the hoses that came with the catch can become pinched under the heat and pressure, and it create a whistling noise. I am thinking about re-install it with some stainless steel braided hoses due to fact that there is quite a bit oil and brown oil mark in and between my upper and lower plenum. I will try to post some picture tomorrow.

 

Modifcations made by all the japanes tuners (Nismo, Prostock...) for the VQ35HR:

 

Installing the Greddy 1000cc in the HR with the GTM HR TT kit is a challenge.

 

I was going to ask you why but I ran into these series of youtube vids:

Like I said, I never caught any oil so I may just revert my PCV system back to stock.

Massive. I doubt I'll need something as crazy.

 

ZOMG, I just figured out why I wasn't catching oil. My can was installed on the wrong side (RED). It should've been installed on the passangers-side (YELLOW):


I'm not sure why it was installed there but I'm going to change it to the proper location. Ironically, I did notice the lower plenum and intake mani were filthy when I was doing some upgrades recently.

 

Get out of here with that DE crap! =P

 

LOL. This thread was entirely too informative for me to not post my concerns. I got the information I needed so posting here was better than starting a new thread and going through the whole motions.

 

Run a catchcan in the "proper" location for about 70k miles and pull your plenum off and check out your tb and you "shouldn't" have any buildup...ppl without one will.

 

Thanks for dangling from my nuts, but be careful my girl is jealous.

 

anyone offer a catch can for the HR yet?

 

can't tell if srs.
