I have 2300 hours on the old Perkins, but no leaks inside the pump. My
problem was solved with a new front gasket and replacement of one of the 6
screws which had the head broken off.
However I recently have been getting a drop or two of oil leakage from the
area behind the raw water pump. My local Perkins dealer has orders some new
seals and gaskets to repair it. The O-ring seal around the throttle linkage
where it enters the engine govenor, is leaking a torepair it they need to
pull off the govenor, replace the O-ring and then 3 gaskets required to
re-install the govenor. Parts are on order from the UK.
