After reading this thread, I'm surprised at how may people are positively referring to the government forcing design choices into cars.

If you watch the old films from the different auto manufacturers, you'd find that they have spent lots on the R&D to get vehicles that are more safe and better performing.

Here is a film from the industry that discusses (in a light hearted way) the innovations:


Governments distort markets and force on the public features that are not necessarily desired with money they extract from your wallet by force. This is especially true in California, where a vehicle can produce far cleaner emissions, but it fails a visual test.

As was mentioned, the PCV system was an industry innovation. The original patent by Bendix was in 1949 under US 2489230.

Well before government involvement.

Don't know about the patent date but US military vehicles used a PCV on vehicles used for fording deep water.

Measure the diameter of the hole in the block and get a grommet that is slightly bigger. I forget what I used, but it was snug with the PCV valve pressed into the middle of it. It was sitting in my toolbox from my tune-up days. Many auto parts stores sell PCV valve grommets in various sizes. You'll have to size one up.
