What is an Oil Catch Can?

Catch Cans like the Mishimoto Universal High-Flow catch can are primarily responsible for catching blow-by that is re-routed by your diesel truck’s crankcase ventilation system or CCV. This blow-by consists of oil and fuel vapors that enter the crankcase after combustion. Your truck’s CCV system will then re-route this oil and vapor through the intake.

Catch can’s have been around a while for gasoline powered automobiles, but what about Diesels? Because of their high compression ratios, diesels are especially susceptible to blow-by. Standard catch cans designed for most gas-powered vehicles won’t work for diesels though. They’re too restrictive, and they can cause serious issues like putting your truck in limp mode. Why does this happen? The high horsepower and torque of diesel trucks leads to very high crankcase pressures. A bigger, high-flowing catch can is needed for diesel applications.

Why Should You Get A Catch Can?

The crankcase ventilation system causes blow-by to enter your truck’s intake. This means your turbocharger, intercooler, intake, and other crucial parts can experience carbon build-up causing premature failure. Wouldn’t you rather pay the small price of a catch can to help prevent major failures like a bad turbocharger?

Why Choose Mishimoto’s High-Flow Universal Catch Can?

Mishimoto’s High-Flow Universal Catch Can was made for diesel trucks. They offer high-flowing catch cans that won’t restrict your CCV system but still capture significant blow-by. Inlet and outlet ports feature 1″ diameters compared to the standard 3/8″ outlets. A massive filter featuring CNC-Machined baffle catches harmful vapors and oil while simultaneously letting crankcase vapors pass through.

Worried about having another part to worry about or having to do more maintenance? Mishimoto makes it easy by allowing you to drain the catch can without removing the filter by using a 3/8 NPT plug on the bottom of the casing. They also provide the necessary hardware and a mounting bracket for easy installation too! Mishimoto also has a lifetime warranty on all of their products.
