Oil fumes, blow by? Need new rings?

Hi Guys,

Ever since I turboed my car I've noticed oil fumes or vapor from the oil tank which is now vented to the atmosphere via a little k&n filter (so the boost wont pressurize it, it's usually feed back into the intake, it's a 3.2). When at operating temp with the oil cap off I get a fair amount of vapor coming out, it stinks and also comes out the small filter. The car doesn't blow smoke on throttle though and is still making lots of power, oil consumption is pretty normal though the car gets very little use.

Does this mean there's blow by? It did it as soon as I vented the oil tank, before I had even boosted the car so I'm thinking this was already there but just burnt through the engine previously. If it is normal I've been thinking about running it through a charcoal filter then venting it as the smell gets to me after a while of driving.

Thanking you in advance, Spence.
