Thanks for letting us know, Redeye. I'll close the thread.
It is not necessarily unusual to find defective parts on a new engine unless the engine is hot-tested on the assembly line - which is done with car engines, but very few other types of engines. The theory says brand new parts often fail ("infant mortality", in the trade) then there is a long period of high reliability, followed by gradual wear-out failures. Reliability engineers call it a "bathtub curve", since the failure rate is high on the left side of the graph, low in the middle, then curves up on the right side of the graph.
