The one I used was a Fisher-Porter same one Chryser Race Group used was about $300.00 30 years ago. I could hook it up as Alan described and if it was bad enough the weight in tube would bounce just spinning on starter. We would check engine every time we loaded car to come home by hooking up meter and just free rev engine to 6500 rpm if Blowby was over 2 cfm engine would come apart we we got home. Difference on a 740 hp engine on dyno at 6 cfm down was down 60 hp to 1 1/2 cfm. Ted Flack showed us how to use it. When Chrysler tested at the race track they used the meter on all wet sump vehicles. Sometimes it was actually mounted in the Vehicle.
