Firstly, thank you for the advise received on engine
alignment, particularly to After Hours NLCT for the link he provided.
Attached are a couple of pictures which I hope are self explanatory. The engine
is a Perkins
. The old (blue) raw water
pipe from the heat exchanger
to the exhaust
pipe was made from thin copper and had a bad kink in it so I decided to bend and weld a new one out of a some heavy wall stainless pipe that I had in my workshop. I always like to make things as simple and straightforward as I can so I eliminated the extra forward facing curves in the blue pipe. Now I'm fretting about it. I absolutely cannot see the point of those extra curves, but surely no-one would put themselves to the trouble if they were not necessary? I don't know much about engines, so will my new pipe be O.K, or can anyone enlighten me as to the shape of the old pipe?
