Unlike many vents, you'll find crankcases; our PVC Valve uses a check valve that only allows crankcase pressure air and gases to flow in one direction. A common mistake is using a simple brass or aluminum fitting without a check valve. This means air is pushed out, but also air can be sucked back in and, in a sense, defeats the purpose of a vent. Inbuilt engines, it's not enough to vent crankcase pressure but control crankcase pressure.
The New 280 is an all-aluminum design for better longevity.
