Hey All,

Was wondering if I could bolt on my Eldo heads from my Police project while
I repair the head from the Ambo?

Intake valve was indeed bent. Needed to hammer the thing out. From the looks
of it the valve could have fused to the guide (since there was some brass
tightly fixed to the valve stem) and that is what kept it open...allowing
the piston to hit the valve and bend it. Not sure if this is the case
because the valve was closed when I pulled the head.

I'm still not sure which was first to go. The push rod bending causing the
valve to bend (see previous email explaining my theory) or vice versa. A bit
of a mystery. Possible there was a lack of flow of oil to the top end too
but there was lots of oil up top when I initially pulled the rocker covers.

Not sure whether to look for something else. At any rate I am happy in some
ways because I think the damage could have been considerably worse.

Ciao...Ian
