I got in 4 fairly long flights today, totalling approximately 50 minutes running time.

After the installation of the NordLock washers, it leaked about 4-5 drops of liquid exhaust residue around the header, but there was no residue on the firewall or inside the cowl. If it were to stay like that, I would consider it a totally acceptable situation. Previously there was enough leakage to make me think there might have been a small loss of horsepower, and it was creating a bit of a mess inside the cowl.
