2016 - 2023 Chevy Camaro SS

    After installation, Mishimoto recommends checking the contents of the baffled catch can every 1,000 miles until a baseline is established. Oil blow-by accumulation will vary with ambient temperatures and driving conditions. It is important that the contents of the can do not rise above the internal baffle.The catch can kit can be installed without removing the intake manifold, by attaching the supplied silicone hoses directly to the manifold.This product will fit with convertible models, the stock strut tower bar must be partially removed to install the catch can bracket.



    The 6.2 liter LT1 is an animal of an engine, but like any engine, it does not enjoy oil in its intake. Enter Mishimoto’s Camaro SS baffled oil catch can! Designed to protect the LT1’s intake from becoming an oil slick, this catch can mounts in-line with the PCV system to separate oil and air using a 50-micron bronze filter. The catch can is mounted away from most intake and supercharger kits to help leave room for future modifications

    This new GM LT1 engine features direct fuel injection, which is great for creating an efficient burn but allows for carbon buildup on the intake valves. Engines with conventional port injection have fuel injected into the intake runners, which helps to wash carbon deposits off the valves. This isn’t the case with the Camaro’s LT1, making the addition of a catch can vital in preventing increased carbon buildup.

    Mishimoto’s 2016 Camaro SS catch can kit features Mishimoto’s 2-port Compact Baffled Oil Catch Can, which features a bronze filter and internal baffle to better separate the oil from the crankcase vapors. Two direct-fit hoses and an application-specific bracket make for a quick and simple installation. To back up Mishimoto’s superior craftsmanship, each 2016 Camaro SS catch can kit comes with the renowned Mishimoto Lifetime Warranty!

    Our catch cans are different from most air-oil-separator (AOS) systems on a few levels. First, our catch cans are not heated. This means that all of the blow-by is able to condense in the can, including low-octane oil vapors and contaminated fuel vapors. Most AOS systems also drain the blow-by back into the oil pan, while our catch cans trap the blow-by and keep it out of the engine permanently. If you’ve seen what we’ve seen in the bottom of our catch cans, you won’t want that draining back into your oil either.

    Why is carbon buildup an issue?

    Modern fuel injection systems utilize either port injection or direct injection. Valve buildups were not a serious concern until DI engines became popular. You may be asking yourself how this affects the valves. To see why this is occurring more prominently with DI engines, we need to evaluate the function of both systems.

    First, we have traditional port injection. In an engine with this system, the injectors are placed inside the intake manifold, and they produce a stream of fuel to atomize and mix with air. This mixture then enters the combustion chamber through a valve.

    As you may know, gasoline has strong solvent properties, meaning it is fantastic for removing grease, tar, and waxes. The fuel mixes in the manifold and then passes through the valve to clean much of the debris and buildup.

    Now to compare, let’s take a look at direct injection.

    The fuel injector is located right in the combustion chamber, unlike the intake manifold location for port injection. This means the valve will not be affected by fuel, so its cleaning properties are not utilized. This setup is one of the primary reasons for problems with DI valve deposits.

    What’s the big deal?

    You may not think this will be a problem for your brand new car, but these deposits can accumulate quite rapidly. Below is a look at the deposits on the valves from a DI engine.

    This buildup can cause drivability issues, CEL illumination, and loss of performance. You purchased your Camaro because it is a high-performance vehicle, so it makes sense to do your best to retain every last bit of horsepower for as long as possible.

    The primary contributor to these buildups is oil entering the intake tract. PCV and CCV systems ventilate pressure within the crankcase and heads to provide optimal pressure within the engine during operation. For emissions purposes, this pressure is vented back to the intake system. The fluid returning to the intake is typically composed of both fuel and oil, not what you want in your intake system.

    Reducing the entry of oil into your intake tract is a wise move, especially if you can install a solution before the vehicle accumulates significant mileage.

    Camaro SS Stock Breather AOS System

    If you were not convinced that this is a real problem, you may be interested to see that the SS has a factory-equipped air oil separator (AOS). Like a catch can, this setup filters fluid before it re-enters the intake. The primary difference is that the AOS returns the fluid to the crankcase, so no draining is required.

    The AOS filters air leaving the two valve-cover breathers. Below you can see each line route.

    These lines route into the separator, which is mounted near the passenger valve cover. Each connection point uses a plastic quick-disconnect fitting.

    After separating within this contraption, the CCV air returns to the intake hose.

    What about the PCV system?

    It is great to see that GM addressed a portion of the CCV system with its AOS. Unfortunately, GM has not added such a setup to the PCV-side of the system. From our findings with other catch can projects, we’ve seen that the PCV line produces more oil byproduct than do the breather lines.

    On the LT1, the PCV is located on the front of the block, just under the throttle body. A short line runs from the valve to a nipple on the intake manifold.

    With this portion of the system left to vent to the manifold, we decided that some additional protection would be wise. Our engineers decided to address this line with an easy-to-install Camaro SS catch can solution.
