Default catch can

Hello everyone. I was wondering if anyone had install tips and/or pictures of a catch can for the hr I've been wanting to install one due to the high amount of blow by these motors have but I'm not sure where I gotta hook up the hoses. Any help would be appreciated, thanks in advance

Your car and you can do what you want, but it is no where near a necessity for a N/A application. If you're blown then sure, but the negligible blow by we have is nothing. Nevertheless, when I typed in catch can in the search box I got a lot of results...

Actually I've heard quite the contrary for the HR. I've heard and observed first hand that there is a significant amount of blow by especially under hard use. And I too typed in catch can in the search bar and got many results but found nothing pertaining to the HR

Not what I've heard. The HR has quite amount of blow by and over time will cause sludge buildup and other unwanted consequences. I'm not in it for the short run, I plan to have this car for a long time.

I know that for the DE, it has tremendous amount of blow-by. I have a Homemade catchcan on my G35 and it caught quite a lot of oil.

I have a GReddy catch can but not yet installed since I need more hoses than supplied. You'll want to install it between the vacuum hose on the passenger side valve cover that goes all the way to the back of the plenum.
The HR has a lot of blow by gases BTW. Take a look inside your throttle bodies, plenums and manifolds.

Thank you for the response I was looking for. I'm not here to debate blow by. I know the HR has significant blow by and I want to install a catch can to minimize the longterm effects. Everyone may have a different opinion but I am set in my ways about this and I just wanted some direction about installing one. Good luck with yours

How can it have a lot of blow by when there's hardly any oil consumption? Mine has no noticeable change on the dipstick between oil changes.

Are you other guys with HRs seeing something different?

Thats because you keep your car under 3 grand.

Agreed. When I keep my car below 3grand which is usually during daily use, I don't burn much if any oil. But, if I run it hard, I deff burn oil. I checked my dipstick after making about 6 passes at the strip and I had lost oil.

Time to bring it in for a consumption test if that's the case. I used to run 30 - 40 passes over a weekend and a few high speed runs and never dropped on the dipstick. This is a farce. If it was needed that bad it would have come from the factory. Whatever blows through would get burnt anyways and no ill effects would come of it. It's car bling.

I have, it's cleaner after 60k miles than almost any other car I have seen besides our civic. I don't baby my car all the time either, it's a fun car, have to have some fun with it

I haven't noticed a drop gone either. But maybe some people aren't using the correct oil or something.

This isn't some made up bs. Its proven fact, check out other catch can threads with pics and you'll c that oil accumulates in the catch can. Sure it may only be an ounce or so over the course of an oil change but I'd rather have it in the catch can than in my intakes or wherever it gets to. Guess I'm just **** like that.
