Thanks for that but I have looked there and on my installation
there is no oil in the heat exchanger and the ony way I can see it getting back from there is via the exhaust
which would have hydauliced and bent the con rods which does not appear to be the case.
I thought it may be the oil cooler but in marinising it looks as though they threw it away!!
The heat exchanger is fitted to the head
in such a way I cannot remove it with standard tools. The engineer
who has it now to do a pressure test on the head hopefully has better tools than I do!!!
There are signs a small core plug
may have blown. All sent to try us and get in the way of sailing!!!
