I have found that water
has been seeping into the engine
from the exhaust
valves once the engine
has been stopped. The perkins
4108 is low in the boat (Claymore 30 motor
sailor) and I have fitted a non return box in the lowest part of the engine space for the top half of the exhaust water
but the water from the manifold to the non return box runs with a limited gradient. This means that when the engine is stopped the last blow of water and exhaust almost fills the low level pipe and has slopped back up the manifold and into the engine. Does anyone know of a fitting that would easily allow me to drain off this water when I stop the engine which would make sure that I dont have a repeat of the problem.
Any slight continued flow of cooloing water from the outside seacock, through the impellor and across the heat exchanger
will soon fill up the pipe to the non return valve. This means I already have to rremember to turn off the sea cock immediately I stop the engine to prevent the flow back of water. Another jog of puliing some king of drain plug
would not be an extra burden.
