Valve guide seals are OK on some INTAKE valves. As a rule I do not use
them on exhaust guides of most air cooled engines.

I put 'Raymond' seals on them also.They would never wearout or seize.
Just a thought,?

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.

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
