The decision of whether to keep the Oil Catch Can kit in your car completely depends on your personal preference and your vehicle's specific setup. If you have observed that the kit is efficiently collecting oil and moisture from your engine, and you are worried about potential problems like carbon buildup, it would be wise to keep the kit. However, if you are not experiencing any noticeable benefits and are concerned about boost leaks, it may be a better option to revert back to the original equipment manufacturer (OEM) setup.
It's crucial to understand that the effectiveness of an Oil Catch Can can be influenced by many factors such as the kit's design, the driving conditions, and the overall condition of your engine. If you ultimately decide to keep the kit, it's essential to check it regularly and clean it out to ensure proper functioning.
