Radium Engineering Dual Fluid Lock Catch Can Kit for Chevrolet Corvette C7 LT1 2014-2019

Radium Dual Fluid Lock Catch Can Kit, Chevrolet Corvette C7 LT1 (2014-2019)

Application: Chevrolet Corvette C7 LT1 – wet sump 2014-2019, dry sump 2014-2016
Part Type: Dual CCV (crankcase vent) Fluid Lock oil catch can kit
Part Number: 20-0986-FL

The Radium 20-0986-FL Dual CCV Catch Can Kit fits a catch can to each crankcase vent on the C7 Corvette LT1 while retaining factory function. At low load the vents see atmospheric pressure, but at high load (WOT) they see high flow out of the crankcase, which would normally leave oil and sludge in the air filter intake pipe.

On wet sump engines each valve cover vents to the intake through its own can. On dry sump engines the LH valve cover vents through its can and the RH valve cover vents through the dry sump tank, then its can. The large anodised bracket mounts near the front LH side of the engine on a polished billet aluminium ground plate that bolts to three OEM grounding points (it conducts electricity, so the grounds are retained). A catch can separates oil and water condensation from the crankcase gases before they reach the intake, helping to keep oil out of the intake tract, intercooler, throttle body and intake manifold. Cleaner inlet air can improve performance and lower hydrocarbon emissions, and the closed system keeps oil vapour out of the cabin.

Each can uses Radium's Fluid Lock design, introduced in 2022: a patented mechanism stops the reservoir from overfilling and traps the collected fluid until it is emptied, so contaminants can't be drawn back into the intake if servicing is missed.

• Large Ports: 10AN ORB inlet and outlet ports
• Drain Port: 4AN ORB drain port
• 2-Step Baffling: Two-step oil separation baffling
• Dipstick: O-ring sealed dipstick to check the fluid level
• Capacity: 207ml (7 fl oz) reservoir
• Direct Fitment: Vehicle-specific bracket, no drilling required

What's Included

• Baffled oil catch cans with integrated condenser and dipstick (x2)
• Anodised aluminium mounting bracket

Optional Parts

• Radium PCV Fluid Lock Catch Can Kit, Chevrolet Corvette C7 LT1 (2014-2019) (20-0985-FL) – adds the PCV-side catch can (or choose the 20-0987-FL triple kit)
• Radium Dual Fluid Lock Catch Can Kit, Chevrolet Corvette C7 LT1 Dry Sump (2017-2019) (20-1286-FL) – the dual catch can kit for 2017-2019 LT1 dry sump cars
• Radium Catch Can Petcock Drain Kit (20-0024) – drain the can without removing the lower reservoir, where there is space under the can

Important Notes

• Dry sump fitment is 2014-2016 only – 2017-2019 LT1 dry sump cars use the 20-1286-FL kit
• Covers the crankcase vent (CCV) side only – it does not include a PCV can
• If fitted together with the PCV kit, keep the hoses off the top of the LH fuel rail
• Cars with Magnetic Ride Control need a wiring harness stay pried up/removed during installation
• There is no fixed emptying interval – start checking the integrated dipstick after 3–4 weeks of driving and adjust from there; PCV cans generally collect more than CCV cans
• Empty by unscrewing the lower reservoir, or fit the optional petcock drain kit where there is space under the can
• Excessive collection can point to an engine issue such as blow-by from engine damage, crankcase windage from an overfilled oil level, poor breather port placement or baffling, or a PCV valve leaking under heavy load
• Installation instructions are available in the Instructions tab

Vehicle Fitment

• Chevrolet Corvette C7 (2014-2019) – LT1 wet sump
• Chevrolet Corvette C7 (2014-2016) – LT1 dry sump
• Not compatible: Chevrolet Corvette C7 (2017-2019) LT1 dry sump – use 20-1286-FL
