I would feel best about pulling the rocker shaft and checking all the freeze plugs up there (not sure how many are in the head).
Make sure none are loose.
Such a cool outcome! The freeze plugs did their job!!!
It sounds like the last few years have just been brutal.
I am sorry to hear about it all.
Now to be faced w/ more tribulation just feels like a kick in the sack.
This can be fixed!
It sounds like you still have your wife and daughters - everything else is mouse turds...
Just thinking out...
Evan, @fj55-100 is good people!
AFAIK, shapeways is just a 3rd party printer. They probably have no idea WTF the parts they print and ship even are, no idea of application, etc. They are simply a 3rd party fulfillment outfit.
