Getting rid of the PCV line?

[deth_1970]

think of it this way, you have compressed burning gases on one side of the ring, and a mild pressure on the other side of the ring, while it is moving down the cylinder those 2 pressures are working against each other, so you don't get maximum pressure on the ring from the combustion and power stroke,

with the PVC hooked up, there is a vacuum in the block, so there is a negative pressure under the ring, causing the ring to be seating better against the cylinder wall due to compressed burning fuel, and less blow by, unless the rings are worn out
