i might be wrong but thats what i read anyway in the article u posted they talk about intercoolers which doesn't exist in n.a engines so.... ---------- http://www.m3forum.net/m3forum/archive/index.php/t-385508.html
I'm assuming your talking about the three sentences out of the entire article that are in parenthesis (IF your vehicle is turbo or supercharged) . Blow by is produced by every vehicle with a PCV. So to say it's useless is wrong. If you read the whole article, which you had to, because you found the two sentences about forced induction, you would have read that the only type of injection system that does NOT benefit from a catch-can is port injection. Tens of thousands of people have them just on the 1st and 2nd generation CTS alone, and I highly doubt people would continue to buy them if they were "useless" Hell on my first gen I along with many others consider it a necessity.

there are many ways to clean them. Starting with simple fuel additives, and injection cleaning procedures, all the way to walnut blasting. That last one of course involves removing the valves from the heads. Have you visually inspected inside your manifold to know just how dirty it is? Because depending on you fuel type and driving habits it could be relatively clean still. But none the less the catch-can regardless of mileage will increase the life span of a motor.
