Has anyone installed a crankcase evacuation system on a 420a turbo? or see any drawbacks to this idea? I cant think of any but i just want to make sure, my friend gave me the parts so I was thinking about installing them...
 
I do not personally have a turbo, but from my knowledge are you talking about an oil catch can to go between the crankcase breather valve that comes through the top of the valve cover and the intake?
If so that is a great way to relieve crankcase pressure at high rpm's and catch the oil and keep your intake system clean.
IMO it's not such a big deal with n/t, but with a turbo is should be a must.

Someone more knowledgeable should chime in as well and elaborate more on why and the nitty gritty of it all.
