question on crankcase breathing
 

I've read a lot of times before that the majority of people tap their intake pipe and run a hose to the crankcase instead of a seperate crankcase filter. Why is that? I changed my setup to that way, and now when i open my oil cap and my car is running my engine starts bogging; i know thats normal since it basically acts as a hole in my intake, but its kinda scary. Also, the way I'd imagine it, under boost my intake is sucking in air like crazy, and my cams are spinning like crazy....with that combination would oil go from the crankcase to that line and into the intake pipe and into the turbines? what keeps oil from not going in that line?

stop opening your oil filler cap when the engine is idling.

you actually only have about 1-2 ~hg. of vaccum in the intake in boost and take in effect the line is only 3/8" OD.

In the high boost honda world they ditch the stock pcv and breather, and add addition ports on the valve cover. Then they run all those line to a catch can that is open to the air, usually with several of those little mini filters.

stock MSM has a catch can with a drain line into the oil pan.

I'd rather keep it in the intake to keep my vacuum in the crankcase. With my poorly sealing rings I would smoke with breather filter or with a catch can into because of the vacuum loss in the crankcase.

when i had an air filter, it would smoke from it D:
