Hi
On our 40 Ocean, D2-55, the pipe that comes out of the heat exchanger to the exhaust elbow has been cut half way along its length and two pipes added into the circuit to install a vented loop.
Is this standard procedure as there is no mention of it in the Volvo schematic and it looks messy and unnecessarily complicated.
Why do you need a vented loop in this part of the chain, the only thing I can think of is to prevent inflow from the exhaust outlet in the hull..
Thanks
