Oil Catch Can

About

What is an Oil Catch Can and How Does It Work? In modern internal combustion engines—especially turbo-diesel trucks, 4WD off-roaders, and high-performance vehicles—combustion gases can escape past the piston rings and into the crankcase, a process known as blow-by. These gases often contain oil mist, unburned fuel vapors, and moisture , which are rerouted through the PCV system back into the intake. This can lead to carbon buildup, EGR system contamination, and even turbocharger wear over time. The SPELAB oil catch can kit addresses this issue directly. Designed for use with both gasoline and diesel engines , it installs between the PCV system and the intake manifold to trap harmful residues before they cycle back into the combustion process. While it doesn’t enhance horsepower or fuel efficiency directly, it offers practical engine protection and lower long-term maintenance , especially for drivers pushing their engines hard. What Are the Benefits of Installing a SPELAB Oil Catch Can? Before diving into SPELAB’s oil catch can kit , it's important to understand what this device is and how it works. An oil catch can is a small reservoir installed between your engine’s PCV (Positive Crankcase Ventilation) or CCV (Crankcase Ventilation) system and the intake manifold. Its job is to trap oil mist, fuel vapors, and moisture from blow-by gases before they re-enter the combustion system. In factory CCV systems—especially on modern turbo-diesel engines like the 2006 Duramax 6.6L , 2017 Ford F-250 6.7L , or 5.7 HEMI —these blow-by gases are often rerouted back into the intake manifold unfiltered. Over time, this causes throttle body sludge, EGR valve contamination, and potential turbocharger damage . Installing a SPELAB oil catch can kit , particularly when paired with a CCV reroute or delete kit , reroutes and filters these gases to ensure cleaner engine operation and long-term reliability.
