I think the only real way to eliminate all intake issues would be a line from the PCV to some tie-in point after the converter. But obviously then you run legally afoul of several things... plus you take the chance of the oil not being hot enough to fully vaporize, and dripping liquid oil out of your exhaust.
I figured that 100% is not achievable... I get that.

The makeup of the oil is really insignificant other than to see what parts of the additives made it all the way through the system.
Good idea, I would be curious to see what it's made up of.
