Morris,
Tank heaters, I was thinking of cold start up, to have warm
oil there straight away, and with the
oil cooler air duct blocked off, would I achieve what the thermostat does?
I am using -12AN for most lines apart from, tank to
oil pump, and scavenge port back to tank, I have thought these lines are monstrous, so I might adjust size, as they are harder to bend, take up more room etc.
Breathing, the oil tank has two 1/2npt ports both going to a separate breather to get rid of oil scavenge air, the penske valley cover has a -12AN fitting which will go to the breather tank, I am hoping that will be enough for a dry sump system!
