Changed the oil and installed the
Bob's Auto Sports catch cans today. I took a bunch of pictures, so it's time for a review!
Here they are. I chose the matte black ones so they didn't stick out like a sore thumb, but there are a lot of other colors available. The vacuum line nipples are already installed, and they used some sort of pipe dope on them to seal them properly.
With my love of carbon fiber, you may be wondering why I didn't get their hydrodipped carbon finish. Easy: hydrodipped carbon looks like shit.
I'm very impressed with the build quality on these things. The insides are properly baffled using a steel wool. This maximizes surface area and helps to condense all of the oil vapor out of the PCV lines.
You can see the baffling here:
Here's one of the mounting brackets. They're beautifully machined and finished, and already installed.
There is a valve on the bottom of each one for draining:
Onto the installation. The longer bracket is used on the passenger side. You remove one of the ground bolts, and install the bracket there using a longer bolt that Bob's Auto Sport provides.
The next step is to remove the factory PCV line and carefully cut along the side of it to remove this 90° elbow. The PCV valve is already in the valve cover; this is just an elbow to make it easier to route. Note that although the OEM line is hard plastic, those 90° elbows actually have fittings on them for lines. Hmmmm...
Next, you need to cut the vacuum lines they send you to the correct length. This is some high-quality, fiber-reinforced multipurpose line from Eaton. It seems OEM quality and should last a long time. The instructions recommend using masking tape to help prevent the lines from fraying while cutting.
Next, you clamp the line onto one of those elbows you cut out of the stock hardline.
This first line took the longest, because it is extremely short, but I didn't want to make it
too short. So I ended up trimming it down several times. Note that the valve cover line goes to the
bottom port on the catch can. This is so engine vacuum pulls the air up through the steel wool baffle and out, leaving the condensed oil vapor to fall to the bottom
The next line runs to the intake manifold using another one of those OEM quick-release elbows.
Now we move onto the driver's side. This catch can actually requires removing that stupid sound tube. (Mine's already been ditched.) It mounts to the underside of one of the sound tube's mounting holes using a set of washers, nut and bolt provided with the kit. This thing was a bit of a pain in the butt to mount, simply because I was afraid of dropping a washer or nut and never seeing it again.
The driver's side OEM hardline has this foam heat insulation around it. You cut that off, and it's the exact same as the passenger side's underneath. It's here I'd like to point out that the quick-release fitting on my airbox tube fought me and ended up completely snapped in two. Fortunately, it's a straight (180°) fitting, so I could just clamp the vacuum line right onto the port.
Here are the driver's side lines installed:
And the finished product:
