The J&L oil separator for the 2019-2022 5.3L/6.2L GM truck (Silverado, Sierra, Yukon, Tahoe, etc.) application bolts to the driver side of the firewall directly next to the coolant reservoir (see photo). This catch can uses factory style quick connect PCV fittings for plug-n-play fitment. This catch can is available in black anodized or clear anodized (silver) finish. The GM truck PCV systems are notorious for oil consumption through the intake. The addition of a catch can helps to limit the amount of oil vapor the can reach the intake manifold which helps to keep the intake tract cleaner and free from oil deposits.
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 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. The tank holds 3oz of fluid. Optional tank extension increases capacity to 6oz.
NOTE: Does NOT fit 2019 "Classic" model trucks. Use Part Number 3085D (2014-2018 style catch can) for those applicaitons.
