Yes the pipes do fracture.
When I was annealing the small feeder to the head, it simply fell to pieces.
There was a hair fracture which failed completely when I heated it. Since
this is a quite crucial feed, if you have the least doubt replace the tubing
with new. Most of the others are drains so are under no pressure and are
much larger anyway. You'll need to anneal them all in any case to allow hand
bending to get the final #exact# fit to the end positions
I havn't found that the oil lines leak from the unions, but beware
deformation of the long narrow union to restrictor pin at the front of the
head. These bend like a banana over time: I straightened mine cold and
filed the face to final flat. Annealing would make the problem worse: leave
the ends alone.
All my sump studs had stretched and I made new ones. They're only mild steel
died 1/4 BSF.
In most matters of rebuilding the MMM engine I found Martin Green's book 'MG
Road Cars Volume 1' an invaluable resource.
Note: pressure test your block in every way that you can. Mine has a hair
crack outward from the water jacket that has only appeared after running the
engine: I havn't quite figured what to do yet.
