[C320-list] Yanmar 3YMG30

[MARSHALL M LUCAS]

I have a 2005 C320 with the Yanmar 3YM engine.  I just had 
the 50 hour checkup done and the mechanic was not able to 
remove the valve cover to adjust the valves.  There is a 
wood bulkhead does not allow sufficient space to remove 
the valve cover.  Has anyone had any experience with this 
situation and if so, how was it resolved?  I have 
contacted my dealer and have left a voice message with 
Catalina.

Thanks!

Marshall
