Most of us have that food that we can't resist but we know isn't going to agree with us. We know the outcome is going to be unpleasant, but we still scarf it down anyways with antacids at the ready all the while asking if it's really worth it. That's sort of the same situation that's happening inside your L15B7. We know that there's blow-by. We know the consequences of leaving the intake valves unprotected. Do we just sit back and use a chemical clean as a sort of temporary relief, or do we look for a more permanent solution?

If you already read our last post, you'll know that a cure for this ailment is underway. So far, we've designed our prototype kit and set our donor vehicle out for the Mishi equivalent of clinical trials, a 1000-mile road test. This cycle tests two perimeters for our solution. The first is to determine the bench line of how much blow-by we expect to collect, which then lets you know how often to empty the can. The other is to ensure that our kit operates safely on the vehicle without any pesky check engine lights. Let's take a look at the final product, and make sure that you stick around for our results.

In the case that you want to add some extra zest to the engine bay, our catch can bracket is also available in Rallye Red.

In this new age of turbocharged Hondas, plenty of components are shared between the different models. As we went over in the last post, some things change slightly between the different trims, which meant that the 1.5T ended up with a specially designed bracket.

Even though the bracket is specific for the 1.5T, that doesn't mean that we couldn't borrow the mounting method from our other Honda catch can designs.

Since Honda utilized the compact but punchy 1.5T in this iteration of the Accord, routing lines and installation is a cinch. Our lines are also J30R7 spec compliant and feature a one-way check valve to keep your catch can from pressurizing.

Now for the question you've all been waiting for"does it actually work or is it just a placebo? Well, our results are in and in 1000 miles our direct-fit kit for the 1.5T powered Accord collected approximately 3-4 ml of blow-by. Granted, this pales in comparison to what we collected in the spicier 2.0T variant, but the constant peppering of the intake valves will eventually lead to the same result.
