[Healeys] Healey Push Rods from Moss

[Dean Caccavo]

Bill,

I had the same experience, but the symptom was a little different.   We
rebuild the motor in our BN7 with parts mostly sourced from AH Spares.  I had
intended to use the original push rods so didn't order those in the first
batch, but after speaking to the machine shop they convinced me to order new. 
Like you, I sourced the rods from Moss.

Run in was fine, but the lash needed adjustment right away. Then again in 100
miles, the I was worried. Turns out in my case the push rod cup (the part the
receives the ball adjuster) was machined too small.   The ball never fully sat
in the cup, so with each valve cycle it was beating itself into the cup a
little further.  It was hard to see.  Only with machine die or a little clay
you could see the gap. 

Moss took back the rods and sent another set.  Also bad.  They never fully
understood the problem.  I reused my old rods and have been ticking along for
several years now.

I did write this up at the time.  Sorry to see that they don't have a handle
on this issue.  They have need pretty good about other issues...
