Mark, et al,
I would suggest that if you used all new lockwashers where required, the
situation was not likely the backing off of the hardware, but rather the
settling of the gaskets and sealing agent at the joints. After some time of
being repeatedly heated and cooled causing expansion and shrinkage, plus the
compressing factoron the gaskets, it's quite common to have to retighten the
joint fasteners.
