That's true....but mine is under the stock airbox mostly out of sight. It is tight though. I'm not a fan of seeing the wheelwell mounted units. I also wanted two large braided lines going in and this fit the bill.

I have the same one mounted where the windshield washer bottle used to mount. I never used it in 5 years, so figured it was time to put the space to better use. I think it is best to mount the can on the driver side away from the cabin air intake.

Hey guys,
I have a 99 ACR with a Roe blower (and the Roe breather on the passenger side) and I had enough oil puking that it was dripping from the water drains off of the inside of the air breather.
When I evaluated it further I realized that it was primarily from the way the hose leading from the valve cover to the cleaner assembly was setup. There's a very shallow rise from the cover to the assembly. Under braking the oil blown into the tube simply dumped into the air cleaner assembly.
I removed the plastic piece (and 5/8 hose) from the valve cover to the air cleaner and replaced it with a section of hose with two 90-degree bends introduced into the system just forward of the valve cover. The way it's in there the oil actually has to travel straight up and backwards slightly in order to make the straight run to the air cleaner assembly. Since most of the oil sloshing was happening under braking (pressure fills the tube with oil, then it sloshes forward under braking), now that it has to actually travel the other direction and straight up I just don't really have a problem.
In practice, this has reduced the oil blown into the intake tremendously (not a drop yet), looks pretty factory, and cost about four bucks.
It might not work for everyone, but I thought it was a pretty trick way to use physics to advantage in this case. And there's no oil to empty anywhere...
(Edit, adding photo)
I am holding the stock piece in my hand, and the mock up for the adjusted piece is installed on the car.

But if I am correct, the oil vapor taken into the intake to the engine will still lower the octane (due to the induction of the oil/vapor) which causes pinging/knocking. Or am I off on this?

Irid, very clever, thanks for sharing.
Would somebody please put up a photo of how the PBJ unit actually attached to the valve covers? Also, how does the PBJ unit drain off?

My can has a drain with a handle on the bottom. The lines come off of the valve covers with hose and fittings in the kit that attach all three connections together. There are 90 degree hose ends, a T, hose, and clamps included for a 15-20 minute install...it is a pretty simple set up.
Hope that helps a little,

YES!!!! You do not want oil vapor running back into the intake!!! It will ignite under compression and cause detination
The simple tweak to my mod is to route the end of the hose into a breather rather than the airbox; the introduction of the backward and vertical run is a mod one can make to a setup using a catch can with a breather on top, although you may never actually get anything into the catch can anymore ;-) I think the vertical component acts a bit as an air/oil seperator as well. The mass of air injested by the motor is quite large compared to the mass kicked back to the airbox via the breather line, and since the line is dry to the touch I doubt that this air is all that "dirty" and I don't think it's impacting the effective octane rating.
Certainly, running the line to a breather rather than to the airbox would introduce less oil vapor into the intake system, but in absolute terms I don't know that what is introduced has any real effect. ymmv!
I don't have a detonation issue, so I didn't feel the need to route the line anywhere other than the stock location in the airbox. I preferred the stealthy look of the install so I ducked the can, and I know in states with visual checks the cans are a big no no.
In any case, I just wanted to throw a simple tweak into the mix - it should at least keep everyone from having to empty out their catch tanks as often.

My new PBJ tank came in today. Powdercoated to Roe Racing red.
What a nice unit it is, and what a great guy to deal with!
Anybody got a few shots of a Roe Supercharger breather line set-up to one of these that they could throw up? Much appreciated.

What I did was to take a inline air compressor moisture filter housing and put it between the hose running back to the intake, very small and works great, no problems.

Other than the container being made of glass that is the perfect size. I've actually found some aluminum bottles about that size.

Its actually hard plastic and works great to see the fluid level, has a drain plug on the bottom.
