Hello all.
I have just serviced my starter motor and in the process, had to remove the heat exchanger. When I did, I inadvertently pulled off a corroded piece of pipe. Unfortunately, this pipe was attached to the oil cooler. Even worse, this is a sod to remove and costs £600 to replace! There is plenty of prior discussion on this apparent design fault on this engine - Yanmar 4JH3E. It doesn't have anodes as it's supposedly a special material that resists corrosion. My photos tend to disagree.
My question is: can this damage be repaired? Attached photos show each side of the unit: where the pipe has broken off and what it should look like.
My next question is: can a cheaper one be fitted? Preferably with anodes that I can check.
Any advice much appeciated!
