Hello to all my wonderful Camaro 2.0T and Cadillac ATS owners! In our last update, we made the big reveal of our patent-pending blow-by tap. We drilled down into the details of how we plan on mining that nasty vein of oil vapor out of your LTG and transporting it to a catch can, instead of into your intake manifold.
Today, we’re going to take it back to basics a little bit and look specifically at that whole “transport” element. To go even further back to basics, check out our technical section to see why blow-by is so bad for your engine over time. You know all about the complex, unique parts of this Camaro catch can project, but what about something as simple and ubiquitous as the hoses?
There are many ways to skin a cat, and there are many ways to route a hose. However, as they say, all you really need to know, you learned in kindergarten. Steve took us back to circle time with a clever new way to route houses in a way that’s more visually representative of how the final product will look. It’s just another way to even more confidently nail down fitment on these Camaro parts – or should I say on this ATS catch can?
That’s right folks, we routed our own 2.0T’s hoses already, so this time, we brought our Camaro’s Cadillac cousin into the R&D facility to custom-tailor some stylish new silicone. But more on that later. Let’s start with an update on our blow-by situation.
This R&D Process is Really Blowing By
First, let’s take a second to pretend that I haven’t made that same blow-by joke numerous times before. Now, let’s take a peek at what we’ve got going on in our catch can after another thousand miles or so on the 2.0T.
As you can see, we are continuing to catch a substantial volume of condensed muckity-muck and evacuate it from the system before it clogs up our Camaro’s internals.
Can in the Cadillac
Now that we’ve further re-affirmed just how much blow-by we’re isolating with this setup, it’s even more crucial to ensure that fitment across both these alpha-platform vehicles is like that of a glove. We’ve got the Camaro nailed down, but there’s not quite as much room to work with in the Caddy, which was generously loaned to us by a customer.
This engine bay necessitates not only a new set of hoses, but also a new bracket for mounting the can. We haven’t revealed our exact placement of the Camaro can yet, but we are still working out a couple additional considerations, and may have some other surprises for you in store there –more on that in a future post!
For now, let’s look at the ATS catch can setup. Steve identified the strut tower as a good mounting location, so first, he fabbed up a quick prototype bracket to ensure fitment.
Next, once measurements and clearances got the A-OK, we cut a more presentable bracket on the waterjet.
Hose in the Caddy
With the bracket all squared away, we needed to determine the optimal route for silicone hoses to pass crankcase vapors to and from our catch can. Steve put his thinking cap on, and once recess was over, it was time for arts and crafts. Armed with pipe cleaners so snazzy that he’s become the envy of second-graders everywhere, Steve took to lining up the hoses in a way that was both functionally and aesthetically pleasing.
Did I mention to you that we made our first prototype of the PCV tap out of Playdoh? We decided not to use that method anymore, though, because we couldn’t get Steve to stop eating it.
Joking aside, here’s Steve, lining everything up to make sure the lines travel a route that is both attractive and unobstructed.
And here’s what we’ve come up with!
From a Different Angle
Due to threading variations in the head from car to car, the angled part of our tap will likely vary in orientation depending on how far into the threading our tap grounds out. We will be using two segments of hose where the CC line meets the blow-by tap. This will allow proper fitment on any car by enabling an L-shaped hose on the tap to point towards your CC line, no matter what the orientation of the tap is. Then, you can cut the CC line to exactly the perfect length you need to meet the L-shaped hose for your specific vehicle.
This photo depicts that setup, although to the untrained eye, it more closely resembles a group of caterpillars having a wild party. The arrows depict the range of possible orientations of the tap.
Once Steve bent the lines into shape, they would provide nice practical models featuring the angles necessary to properly route our hoses.
You’ve got a good idea of how this kit is shaping up both for the ATS catch can and for the Camaro catch can. Today, we took a look at even more blow-by that we collected, and we also went into detail on Steve’s cool new way of laying out hoses. Next time, we’ll have some more pictures of all this work for you, as well as some more details on the Camaro’s mounting bracket.
Thanks, and stay tuned!
