Just a update on this post....I know it's been a while but I am the new owner of this boat.....reasons for diesel in the oil....piston rings knackered,barrel bores at .061,lift pump diaphragm split, injectors assembled incorrectly, fuel lines bodged,steel washers where there should be copper washers, infact so many cowboy bodges too many to list but theres just a few to get on with .....barrels have been replaced back to standard new pistons and rings a complete overall of the diesel fuel system+lift pump....oh not to mention that many cat hairs around the cooling fan and fins I could have built a tiger!!!!!....now alls good?
