Turbo oil drain
I need to knock up a turbo oil drain from a normal mitsibishi style flange to some form of sump fitting.
My inital thought was to get a threaded fitting with a hose tail for the sump and then run a piece of hose and two crimps but what spec of hose?
The other alternative is to try and modify some OE return pipe by cutting and welding it?
I notice most OE manufacturers use a hard steel pipe, how would one protect a rubber one against the heat from the turbine housing?
Cheers

On mine there is a 100mm fall, sump fitting must be above oil level in sump, use large drain hose (19mm) because of oil froffing.

You might want to check that, constant immersion in hot oil will cause standard silicone hose to swell up. Flouro-lined hose would be a better bet
here.
Normal oil cooler hose will work, but the very high temperature of the oil leaving the turbo will limit it's life.

I wish the one in my car (Fiat Coupe) was above the oil level, I discovered it wasn't when I removed the turbo...
