I've always believed in using oil catch cans on all my cars so I want to install one on my recently purchased MCS. my question is this: the catch cans on my previous cars did a really good job at "catching" a lot of crud from entering the intake tract. so I'm hoping the same will be the case once I order one for my MCS. I've read on some forums how the N18 turbo engine has some issues with catch cans effectiveness. why's this?

also...

I'm currently looking at the NM Engineering can. I'm hoping this is a good can that will serve the purpose of catching most of the crankcase garbage that would normally make a mess in the top half of my engine.

opinions on the NM Engineering can and overall opinions in catch cans in general will be appreciated.
