Pontisteve said:But crankcase vapors may be a little more than that. The crankcase is full of contaminants from the combustion process, such as excess fuel and exhaust. Whatever can blow by the rings. That stuff is not so good, and is the very reason why we have a pcv valve in the first place.
That is an inaccurrate statement. PVC stands for Positive Crankcase Ventilation. The reason for the PVC system on any engine is to remove the presure created by the spinning of the Crank, Windage. If they did not have the PVC, your engine would blow out the gaskets, the weakest point in the closed system.
The vapors that are being drawn into the intake, and eventually the combustion chamber, are laiden with oil and need to be "cleaned" by whatever means you have available. Now I'm not promoting Tucker's product but I surely don't see any drawbacks to it either. I personally have a Oil Seperator on my car and it works just fine. I wouldn't mind seeing how much less oil is collected by my seperator with this product installed. I think that would be a true test of it's functionality.
I have to agree with a few posters whereby the oil that is collected and returned to the engine is the same oil that is in the oil pan. I don't see how it became acidic all of a sudden in a closed system.
