Oil flow in a factory bypass system?

[gavinnz]

I will do some more re search on this subject tonight. I am not sure if engine oil gets hot enough to ulter the structure of copper. After the pipe is made with the right curves and anti vibration coils it can be annealed again to soften the copper. The coils don't stop the vibration, they deal with it. On a side note the boat motor will be more firmly held on it's bronze marine mounts and old knakered car mounts!

There´s copper lines and there´s coppper lines...the ones alloyed with nickel don´t work harden and are the only ones aproved for brakelines.
And coiling them up in a spiral for allowing movement is a pretty common metod if wanting to avoid hoses.
