Curious too. Any pics

 

I have owned my RC F for several months and I just learned about this. I'll be checking my intake for oil in short order. I don't track my car but I drive it hard on a daily basis. If I need a catch can I'm not going to be happy. Lexus has had years to resolve this issue...

 

the dual radium can looks like this installed on the RC-F. I'm probably going to do this route because of the blue on RR racing is not a color i would like in my engine bay. it looks like a pasty baby blue or something.

 

Yeah, if I end up doing this I'll be going that route. One reason being that I have to cut my engine cover for the RR Racing option. I noticed your engine cover has been cut too. But I see that it is possible to route around it if one chooses.

 

I have the Air/Oil Separator and like it. The blue color tubing isn't bad actually and matches the F logo color on the engine cover. Been driving the car fairly hard on the street and have not accumulated any oil yet.

 

I installed RR's Air/Oil Seperator last spring. No oil in it after approx. 1k miles of driving including 27 runs at the strip & wot runs to set the kclv.

I always make sure to check the thumb screws holding the canister to the bracket whenever I'm under the hood.

The RR unit has an external gauge and no tools are required for removal.

The Radium unit looks cool, though, for those that care.

 

Here is mine installed with the tuned intake, rarely drive mines so its a bit dusty...

 

This is actually one of the installs I did.

 

i have one for sale if anyone is interested

A few notes regarding some of the comments in this thread:

(1) If you are not getting accumulation of oil in your RR Racing AOS, it is likely because you are not getting the oil hot enough, and are not driving hard enough (combination of high rpm and high G cornering).
(2) NUMEROUS customers have shown massive accumulation of oil in our AOS at the track -- using various oils -- the AOS works for its intended purpose, and is proven to work.
(3) If you do not track your car, or do not drive your car hard enough to ever see 5 bars on the oil temp light, you likely do not need an AOS of any kind.

I've seen oil on the port in the throttle body on my car. i drive hard a few times a week, but haven't hit the track yet besides the drag strip. I think it'll be beneficial regardless if you track or not, at least in my case it would help. I'm curious to see what kind of results I get with daily driving.

 

Having dealt with a lot of IS-F's, I find that there is a huge variabilty in how people drive the street. I have seem some actually fill their AOS's in street driving in 300-400 miles, and to me that is insane because even when I drive on the street tuning and pushing it I do not manage to fill it that quickly! Some people drive it and get maybe 5-6 tbsp in 1000 miles of driving, it varies.

Forgot to mention a few thoughts I had on that custom Radium setup.

(1) There is no reason to add a catch can to the valve cover breathers... just using an external breather as we do is more than sufficient. Even after 2 years of track abuse, our filter is still clean because most of the vapors simply condense in the hose and leak back down. The scavenge pumps in the heads are very effective. and

(2) Other than the added cost of the Radium setup ($300 without connections/tubing) one thing to consider is that you would have to disconnect a bunch of screws and permanent tube connections to empty it. When you are at the track, that is a big inconvenience, IMO, as most of our customers find that they are nearly filling the AOS every 20-30 minutes of track time, especially on a hot day. Our AOS made to be easily removed with 2 thumb screws and all the oil lines use quick connect fittings.

(3) I do not see how the radium can is more effective than our AOS. Looking at their website, the internals look to be pretty much an empty can. If you look below, our AOS has a venturi generator that spins the incoming vapors causing them to condense on the walls of the can, and also features a metal sponge filter -- and its 1/2 the price of an empty can

I have this setup. Was one of my first mods. I rarely drive my car hard and most of the time baby it. I still accumulate oil. Just takes 6 months before it reaches a quarter of the way. I would recommend this to anyone. Recirculated oil is never good. Thanks for the great mods. Taxes will be buying header, tune and tuned intake. Look forward to the gains. Keep making great stuff Rafi!!!

 

Has anyone done a UOA on the contents of the AOS? I really doubt it is pure oil. If it were, I'd see a lower oil level after a track weekend. I have yet to observe this.
