FAQs
Q: What is an oil catch can and why do I need one?
A: An oil catch can is a device that traps oil and moisture from the PCV (Positive Crankcase Ventilation) system before it enters the intake manifold. This prevents oil buildup in the intake, which can reduce engine performance and fuel economy.
Q: How often do I need to drain an oil catch can?
A: The frequency of draining depends on your driving habits and engine condition. Check it every few weeks initially, then adjust based on how quickly it fills up. Some people need to drain theirs every oil change, others more often.
Q: Will an oil catch can void my warranty?
A: Installing an oil catch can shouldn’t void your warranty, but it’s always best to check with your dealer. As long as it’s properly installed and doesn’t cause any engine damage, it shouldn’t be an issue.
Q: Are universal oil catch cans as good as vehicle-specific ones?
A: Vehicle-specific catch cans are generally easier to install and provide a better fit. However, a good universal catch can can be just as effective if properly installed and maintained.
Q: Where does an oil catch can get installed?
A: It’s installed in the PCV system, between the PCV valve and the intake manifold. The exact location varies depending on the vehicle.
Conclusion
An oil catch can is a worthwhile investment for any 5.3 Silverado owner looking to protect their engine and maintain peak performance. Choosing the right one depends on your budget, driving habits, and mechanical skills.
