      Minimize Engine Sludge. Prevent engine sludge from hampering your V8 powered GMC Sierra's performance by installing a C&L Oil Separator. Crankcase exhaust gases (better known as blow-by) is an oily vapor that re-enters through your engines PCV system and gradually coats the inside of your throttle body and intake manifold. Overtime this oily residue thickens and becomes engine sludge which will rob you of power. However, an Oil Separator (sometimes known as a Catch Can) will capture these blow-by gases before they are able to re-enter the system to prevent the formation of this engine sludge.

      Quality Construction. C&L manufactures their Oil Separator from the high quality aluminum for excellent durability and long-lasting service. CNC machined to precise specifications, this Oil Separator is completed in black anodized finish for great under hood looks and long lasting corrosion resistance.

      Straight Forward Installation. C&L engineered their Oil Separator to be installed in under 30 minutes with just basic hand tools. This kit includes two new PCV lines, but you will be required to reuse the original factory PCV fittings, this will allow for an easy plug-and-play installation.

      Application. This C&L Oil Separator; Black; Driver Side is designed to fit 2014-2018 V8 equipped GMC Sierra 1500 models.
