Radium 2007-2021 Tundra Dual Catch Can Kit Fluid Lock

For the ultimate in engine protection, Radium recommends the Tundra 20-0240-FL Dual Catch Can Kit, Fluid Lock (shown below).

The dual catch can kit utilizes both the "Crankcase" catch can and "PCV" catch can.

The 20-0238-FL PCV Catch Can Kit, Fluid Lock runs inline with the PCV (positive crankcase ventilation) valve. When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV "check" valve closes and, thus, this hose experiences no flow. Conversely, the PCV hose will experience "metered" vacuum when the engine is idling, low load cruising, and decelerating. This would normally draw unwanted crankcase vapor, unspent fuel, and oil sludge into the intake manifold immediately after a high load run. Note: Because the Radium catch cans are pressure sealed, they are great for boosted applications as well so connecting to the intake manifold is permitted. 
The CCV Catch Can Kit, Fluid Lock comes with 2 mounting brackets. One bracket will be disregarded depending if the PCV kit will also be used. The crankcase vent runs inline with the 1/2" valve cover breather port. At low loads it experiences atmospheric pressure, but when the engine is at high load (WOT), this hose will experience vacuum and would normally be drawing unwanted crankcase vapors, unspent fuel, and oil sludge into the air filter intake pipe. If the engine is turbocharged or supercharged and you are finding oil accumulation stuck in the intercooler, this catch can is a necessity as oil will lower the thermal efficiency properties of the heat exchange process.
