I've had one on since about 50 miles, currently at about 8,800 miles... This is after about 750-800 miles since I last emptied it... Stock LT1, no mods...

I'm guessing that is about an ounce, so in 8800 miles I've probably kepts about 10-11oz of oil off my valves, is it perfect? No... Is it catching everything, I doubt it, but the one thing I can say for sure is there is 10-11oz LESS oil that has drifted over my very hot intake valves so there is VERY likely less coking of the valves... The way I look at it, if I'm only catching 50% of the blowby, then at 100K miles my valves will look like stock 50K valves... To me, cheap insurance... (Mishimoto Catch Can)

Your Mileage May Vary...
