Baffled Oil Catch Can, fits Nissan Titan XD 5.0L Cummins 2016-2019

If you remember from our last post about the Titan XD catch can, we ran into some challenges with the first and second prototypes. Since then we have perfected our design, so without further delay, let's look at our final prototype for testing.

Final Prototype

With the check engine light vanquished, our last update left us with a slightly different hurdle to climb. A buildup of condensation in the system had us a tad worried about possible freezing in the winter. Little did we know that the solution was right in the Titan's engine bay. One of the benefits of working on a larger truck is that there is more room under the hood to work with. We used this to our advantage and decided to relocate the can to another spot in the engine bay - one that would see more heat. The idea is that extra heat introduced to the catch can will burn off a good deal of the moisture and prevent freezing of the can. A fine theory, but let's see it in practice.

If you remember from our last post about the Titan XD catch can, we ran into some challenges with the first prototype. Since our existing catch can design did not agree with the Titan, it was back to the drawing board for our lead engineer, Dan.

Updated Design

Our standard catch can when installed on the Titan was generating a code causing the truck to go into limp mode. The cause of the code stemmed from our standard catch can being too restrictive for the Titan's beefy Cummins engine. This is not surprising, given the 50 micron filter and smaller design of the can, which was originally designed for gasoline-powered cars. This catch can design functions beautifully on smaller turbo engines such as the Focus and Fiesta, as well as larger American V8s in the new-generation Camaro SS and Mustang GT. It just might not be suitable for the turbo diesel V8 in our

Here at Mishimoto, we know the importance of a good catch can as far as preventative maintenance goes. For most vehicles, installing a catch can means protecting your engine from the silent monster that is blow-by. Blow by can consist of excess oil, fuel, moisture, and pure evil. Engines with direct-injection, like our good friend the Titan XD, are prone to blow-by creeping its way back into the engine through the intake, and caking debris on valves which can be very harmful to an engine over time.
