New engine has loss of compression

To Crazycuda; Yeah me to. Thats why I said approximate, and in this case, with rounding, comes out to the same. And you dont have to know about; pi times(r squared). Its even hard to type.
Then after the engine is built, I roll it over on the stand until one plughole is up. Then with piston at true TDC I pour a measured quantity of oil into the hole, to see if it matches the math.I use a motoroil hoping I can get the job done before any leaks past the ring-gap.I tried other liquids, unsuccessfully.As a sidenote; Plasma Moly file fits seal pretty nice.Next time around, I might try gapless.
