    Oil separator extention

    Hopefully I never need the extra capacity.
    1500 miles on my new Ford F-150 5 liter and barely covered the bottom with oil but plan on taking a long trip and just want the price of mind.

    JLT 3.0 Oil Separator Can Extension

    Posted by Mick on Mar 26th 2020

    If you tired of emptying the little 3oz. can, then buy this extension can, for over twice the capacity! I installed this on my 2017 Ford Expedition, with the fire wall install. The can fits tightly, but has no cleanance issues. I just wish it was a one piece can instead of the extension. A one piece design would eleminated the chance of a leak when the o-ring drys out. so be sure to keep it lubricated. Hats off to JLT's R&D team for coming out with yet a simple but great upgrade to the 3.0 oil separator!

    Works very well. Wish you would've made this available sooner for the f150 ecoboosts.
