J&L (JLT) 3.0 Oil Separator – Catch Can – 2011-2023 F150 5.0L

During the process of venting crankcase pressure back through your intake track, large amounts of oil, in the form of vapors can gather/accumulate in your intake tube, intake manifold runners and even dilute your gas, lowering its octane level. This happens in all engines and is even worse with forced inducted vehicles (supercharged and turbocharged) as crankcase pressures are increased. Filtering consists of a fine mesh stainless steel screen that traps fine oil vapors and releases them once heavy enough to fall. They then pass through a 1/2" thick 1/16th" aluminum honeycomb filter where they grow even larger and then fall into the bottom. By the time the oil gets through the filter it's too heavy to be passed on into the intake. Drain it every 5000-7000 miles and you will never come close to filling it.
