A month after I finished the resto on mine I took it on a 1500 mile trip to the Redwoods and back. Trip was great. Thought the engine was a tad on the loud side, but never having owned a 40 I thought it must be normal. Got to the Redwoods fine. Drove around a bit. Headed home. Got within 50 miles of home and started to lose a little power. Made it home but could tell something wasn't quite right. Turned out to be the shop that did the rebuild on my engine flipped the headgasket. 1500 + miles with no oil to the top end! The shop redid the head and I reintalled correctly.
