Here is Bullet's first response:
Hello Rene,
for the lifter to have that much damage to the wheel the problem started from the beginning of running the engine.
The tie bar of the lifter should not have any stress on it unless something hits it or the camshaft is improperly installed.
What type of damage do the other lifters have? If the tie bars have similar wear it could be an installation issue.
What damage does the camshaft have?
Chris
They are in bad faith!
I told them I knew this happened to Rocky a few years ago and I'm waiting for their second response
I have run about 1600 miles since the engine rebuild.
It is true that the tie bar do not have any stress but I think that it undergoes heat treatment to harden it and if this treatment is poorly done, it becomes fragile and breaks with vibrations.
