Does Your F-150 Need a Catch Can?
In this episode of AmericanTrucks’ (AT) ‘What’s Up With That?’ YouTube Series, Justin Dugan performs a continuous effectiveness test on oil separators using his 2017 F-150 Raptor. An oil separator — sometimes referred to as a ‘catch can’ — is installed in-line with a vehicle’s positive crankcase ventilation (PCV) system to trap blow-by. Since forced-induction engines are prone to blow-by, where increased cylinder pressures force oil past the piston rings into the engine’s crankcase, an oil separator is beneficial in capturing oily vapors to prevent coking on intake valves. Catch cans can be extremely useful in maintaining and safeguarding direct-injected engines that lack supplemental port injection, such as the 2011-2014 3.5L EcoBoost as well as 2015-2017 2.7L (Nano) EcoBoost.
In this video, Justin explains ‘Blow-by’, as well as the history and significance of PCV systems, using a series of animated graphics. After diving into the construction and operation of the JLT V3.0 oil separator, Justin demonstrates how easy it is to install on his Gen 2 Raptor before performing a 4 weeklong, 2,000-mile test. Finally, Justin harks back to his high school science lab days, measuring the captured oily residue with the use of a graduated cylinder.
