Hey, brother! (What's your name?)
This is a common fear, as the industry has been very thorough with their brainwashing about this silly system. They tell a piece of the truth, just enough to lead you to believe a lie.
I made a thread that covers it, and it has been quite heavily visited. You can find it here:
Modification of the PCV System - Groovy Forums
Read the whole thing.
In the future, you can use the search tab at the top of every page. Once you enter the search term(s), scroll down the page and hit the search button. You'd bee amazed at what you can find here!
And at the bottom of the thread, there's a checkbox so you can subscribe to the threads you find interesting. I encourage you STRONGLY to use it!
And go to the thread Welcome Mat > New Members Check in Here and write up a nice introduction for yourself. Most here have done that, so you can get to know the rest of the guys. And, they will all be notified of your arrival and will welcome you like the prodigal son.
Welcome!!!
I look forward to your successes!
Ron
