The J&L JLT3086D-B Oil Separator 3.0 helps reduce oil vapor buildup in the intake tube, intake manifold runners, and combustion system of compatible Chevrolet Silverado and GMC Sierra 1500 trucks. Crankcase vapors can carry suspended oil through the PCV system, and this issue may become more pronounced in engines operating under increased crankcase pressure. Installed on the driver side, this black anodized separator helps capture those vapors before they can continue into the intake tract.
The separator uses a multistage filtration system designed to collect fine oil mist while allowing cleaned air to pass through. A stainless steel mesh screen traps smaller vapor particles, while an aluminum honeycomb filter encourages the captured oil to combine into heavier droplets that fall into the removable reservoir. The solid billet aluminum body provides durable construction, and the knurled tank base allows for convenient removal during service. An O-ring seal helps maintain a secure, leak-resistant fit.
With a 3-ounce fluid capacity, the J&L Oil Separator 3.0 is designed for routine maintenance rather than excessive storage. Inspect and drain the reservoir approximately every 2,000 to 3,000 miles, depending on driving conditions and engine operation. Quick-connect PCV fittings support a clean installation, while the application-specific design is intended for select 2019-2026 Chevrolet Silverado and GMC Sierra 1500 models equipped with the 5.3L or 6.2L engine. Verify vehicle fitment before installation.
