Well, first off is that Catch Can design will do little to benefit the engine due to it only trapping app. 15% of what enters it and allows the rest to be pulled through and still ingested.
Next is understanding what your PCV does to keep your engine alive. It constantly flushes the contaminant laden vapors from the crankcase so the engine does not wear out in 30-40k miles. What is caught in a good effective system is as follows:
70% is water and acids, 23% is raw fuel with a GDI engine, and only 7% is oil, and it is saturated with abrasive particulate matter. So if returned to the crankcase, your engine would not be long for this World. Most look to install a proper system to benefit the engine, not harm it.
We share these technical facts all the time and much more.
Below is how our top system impacts the oil over time as we improve the removal of the combustion byproducts substantially so the oil stays clean longer. This example is from a tech that challenged that claim about our E2-X systems designed for the GDI engines and he tested himself proving it. This is NOT from us. As we always share independent test data so our bias is not present:
Hope that helps you to understand this is not as simple as bolting on what is basically a beer can with fittings as most catchcans are not much more than that. And knowledge of what the PCV system does to keep your engine alive when several defeat the systems functions with breathers, etc.
Cheers!
