Yes, the motor was dynoed and they claimed that it didn't leak while it was running, however within the first minute of running after reinstalling the engine, there was a puddle of oil on the floor. I'm not sure if something is machined wrong with the block or if it is still blowby that is causing the leak. I unfortunately had to accept my loss in getting it fixed by them and eat the Bill. I'm just trying to keep moving forward and get it straightened out so that I can enjoy the car.. That's still my main issue to fix once I get the motor to sit correctly and the clearance issues solved.
