A small canister that plumbs into the crankcase ventilation line and catches the oil mist the engine would otherwise breathe back in. Inside, a stainless mesh screen and an aluminium honeycomb pull the oil out of the vapour and drop it into a 3 ounce tank you empty at oil changes.
why this one — On a modern HEMI that oil mist ends up as carbon on the intake valves and as fuel-diluting residue in the manifold, and a separator is the cheapest way to stop feeding it back in. Compared with everything else in this lane it is the least visible money you can spend, which is exactly the point. Two honest caveats: you have to actually remember to drain the 3 ounce tank, and J&L itself states the part is not CARB exempt, so it is not sold or used legally in California or the states that follow California emission rules.
- Requires: New body (DT) 5.7L only - J&L states it excludes Ram 1500 Classic and Warlock. Also listed for the 2022-2024 Jeep Wagoneer 5.7L. J&L states this part is NOT CARB EXEMPT and is not legal for sale or use in California or in states that have adopted California emission standards. Confirm your own state rules before buying; nothing here is legal advice.
