Radium Engineering Oil Catch Can Kits | GM LS Engines (20-0260-FL / 20-0785-FL)

LS engines run forever, and their PCV systems spend that entire lifetime feeding oil vapor to the intake.

Whether it is a stock truck motor or a cammed swap, the LS PCV circuit pulls crankcase vapor toward the manifold every time vacuum arrives. The Radium Engineering Catch Can Kit for GM LS Engines plumbs a Fluid Lock catch can inline with the PCV tube, mounting to the front of the engine block and drawing oil and water condensation out of the PCV gasses before the intake ever sees them. The kit includes everything for a complete installation, and the sealed can architecture suits naturally aspirated and boosted LS builds alike.

What You'll Feel

• The intake manifold and throttle body kept free of oil film across the LS's famous longevity
• Cleaner combustion and effectively higher octane from de-oiled inlet air, meaningful on boosted and high-compression builds
• Condensation caught in the can instead of circulating with the vapor
• A block-mounted install that travels with the engine through swaps
• Simple dipstick service on the schedule the engine sets

Features

• Fluid Lock catch can: 10AN ORB ports, 4AN ORB drain port, 2-step oil separation baffling, O-ring sealed dipstick
• Mounts to the front of the LS engine block; plumbs inline with the PCV tube
• Complete kit with bracket, hoses, fittings, and hardware for a full installation
• Pressure sealed can suitable for naturally aspirated and forced induction applications
• Closed loop routing preserves emissions-legal operation

Choose Your Version

Two versions cover the LS family. 20-0260-FL suits LS1 and LS6 engines, while 20-0785-FL suits LS2, LS3 and LS7 engines with hardware to match those blocks. Select your engine from the options above.

Building a 2005-2013 C6 Corvette? Pair the LS2/LS3/LS7 PCV kit with the C6-specific CCV and Dual CCV catch can kits (20-0786-FL and 20-0787-FL) for complete crankcase ventilation coverage on both sides of the engine.

The Details

Block mounting is the smart choice for the LS's ecosystem, since these engines move between trucks, muscle cars, and swap chassis constantly, and a catch can bolted to the engine rather than the body comes along for every ride. Functionally, the can's two-step baffling separates oil and water from the PCV stream and holds them behind the Fluid Lock mechanism, which prevents an overdue service from ever pushing the collection into the manifold. Service follows the usual rhythm: check the dipstick starting at 3 to 4 weeks of driving to learn the engine's collection rate, drain by unscrewing the reservoir or through the optional petcock kit, and treat unusually heavy collection as diagnostic information about ring seal or crankcase pressure worth investigating.
