Blow-By Gauge

B&B’s Blow-By Flow Meter is the only effective way to measure piston ring sealing with the engine running. Blow-by is the pressure that builds up inside the engine crankcase and escapes through the breather in the valve cover. That pressure is actually combustion gases that get down the cylinder walls past the piston rings. Obviously, the more blow-by that comes out of the valve covers, the more problems that exist with the rings.
