[AT] Kubota M5700 noise

[Cecil Bearden]

I noticed that the click is easier to hear at idle.  Can you take off 
the valve cover and run it at idle for a bit?  While idling and valve 
cover off, push down on each side of the rocker arms with a hammer 
handle or similar and see if the noise stops.  You could have some worn 
rocker arm bushings.  I had on old ford 292 that did that.  It would 
drop a pushrod sometimes if you over revved it like when it got stuck in 
mud...
