Ken, you really should remove the cylinders to replace the 0-ring at 
the bottom of the cylinder barrels.  They are most likely dried up and hard 
and may not reseal therefore causing an oil/coolant leak.  UAP has a tool 
that will make installing the rings into the cylinders easier than with the 
hose clamp.  I have done both and both methods require an ultimate amount of 
patience and perseverance !
