The following technical points are made to challenge your own knowledge (which you should be welcoming gladly in the interest of technical progress), as well as provide a knowledge base for other readers to reference when considering similar efforts.
The use of catch cans has been widely debunked as unnecessary on this forum, and I challenged your notion that it was beneficial or necessary. I've compiled a list of technical points and follow-up questions I feel appropriate given the subject line of this thread and the inevitable google hits it will attract:
1. No statistically significant failures or have been attributed to this engine with respect to either sensors, seals, or other components as a direct result of oil consumption. These engine components are oil and fuel-safe and to date have not been reported as damaged, compromised, or otherwise degraded as a result of the oil found in the intake path. Do you disagree with these statements? If no, what exact problem are you trying to solve?
2. Oil found in the intake manifold, throttle body, and intake tract downstream of the turbo has not been proven to be exclusively or even mostly from the PCV outlet at the turbo inlet, and may also be caused by oil seeping through the turbo seals. Have you identified where the oil is coming from?
3. The use of a cheap, low-volatility synthetic oil such as Pennzoil Platinum 5W-30, with a 9% NOACK volatility, significantly reduces oil consumption by means of vaporization to negligible and almost visually immeasurable levels. As a result, oil consumption with an otherwise properly functioning PCV system is not a concern. Do you agree with these statements?
4. Catch cans are well-known to accumulate significant levels of condensation and require regular maintenance. That condensation freezes in the winter and, left unattended, can block the PCV port entirely. Do you agree with this statement?
The above points can be summarized as follows: what documented problem (failure/issue) are you trying to solve or prevent with the use of a catch can? Another way to re-word this question is, what failures/issues will someone experience by not installing a catch can, and where are those failures/issues documented? Note: we have members with vehicles that have run for over 300,000 miles that are not reporting any failures directly correlated with or caused by oil being in the intake tract.
