put my turbo back together today and mounted it for the first time (re-clocked- cleaned and painted)
The oil supply line barely fit- (since the turbo is about 4 inches farther back now)
Was looking at the drain tube.
I found a copper pipe the exact same size as the steel one. The steel one has the diamond flange silver soldered into the tube.
I can un-solder it and possibly re silver solder it to the copper tube- which I can either bend to add copper elbows to make it go to the drain snout in block. Any good reason copper wouldn't work ? Only issues I can think of might be corrosion or fatigue resistance..... (can paint the outside- )
Another possibility I remembered was more unusual-
I have a piece of all stainless soft flexible air ( I think) hose. It is composed of 3 layers of stainless steel- inner - middle and outer.
One is a braided mesh, another is interlocking short tubes, and I cant remember what the other layer looks like.
Some how I guess it manages to be airtight. It is very flexible (at least as much as heater hose)
Anyone used this ?????? I believe it was terminated with silver soldered-on ends. (has none now)
I don't even know what this stuff is called ..... never seen a piece this long either......
It is about 3/4 ID and about 1 inch OD and about 5 feet long.....
I think it is like this (http://www.metraflex.com/flexmet_superflex.php )
Also- are there any rubber hoses (oil proof) with external braid that would be reliable enough ?
